Cathodic Protection-Corrosion resistance and cathodic protection addresses new challenges

Cathodic protection is essential in protecting metal applications in a range of conditions that can lead to corrosion activity. The metal anode used in the process shields the metal from potential corrosion. This particular protective measure is particularly beneficial in environments where pieces are submerged.

What is cathodic protection?

Cathodic protection consists of using a metal anode to eliminate or control corrosion. Cathodic protection involves the use of a sacrificial metal layer or barrier that is exposed to the corrosive environment. In acting as a barrier, the other metal is protected. The goal is to protect the various applications from rust accumulation. The actual anode is dissolved when the application is submerged to eliminate corrosion from happening.

Common scenarios where they are used

Any steel application that is ever submerged in water are treated using this process. Cathodic protection can be used in pipelines, piles, boat hulls, storage tanks, water heaters and oil well. Coatings like zinc are used to prevent the rust activities. Metallic structures can be protected with cathodic protection. In some cases, the protective method can be used in conjunction with a DC electrical power source for additional activity.

Other applications where cathodic protection is used

• Wind turbines
• Generators
• Pontoons
• Dock gates
• Water tanks

As an alternative to other corrosion control methods

Cathodic protection is considered a good alternative to protective coatings. For buried applications and submersion in waterfront structures, the cathodic protection method is the preferred means of controlling corrosion. This is because compliance and regulatory requirements are more easily met using cathodic protection. There are a number of safety and environmental consequences for application failure. Federal, state and government entities continually increase their requirements for general storage and use of metal applications to prevent disastrous or dangerous conditions from happening. Cathodic protection addresses the need for improved corrosion resistance to meet these new challenges.

Using Capac corrosion systems

Capac corrosion protection systems provide an automatic cathodic protection for boats. The boats can be submerged without experiencing corrosion and rust. An automated controller, a control electrode, surface anode and a meter are used as a part of the system. The protective current is released from the anode and flows into the water to submerged metal parts to reduce and eliminate corrosion. Anode currents are increased automatically in the system whenever the electrode potential drops beneath the preset control value.

Advantages of using such a system

The user-friendly systems put protection in complete control of the operator. Overhead associated with labor are reduced because of the automation features and reduced reliance on manual operation. Easier maintenance resulting from cathodic protection reduces cost of ownerhip. Oscillation and overprotection are other problems managed with the system.

Cathode protection is necessary for a variety of applications. Since required in a range of applications, Capac corrosion protection systems make it easier to adhere to compliance standards. Capac systems provide a reduced maintenance, less labor intensive way to prevent corrosion from causing damage to applications vulnerable to the problem.

How Much Should You Pay For Web Hosting?

Your website is the face of your business, so it’s extremely important that you make a good impression with your website. Not only can having a great website make you look more professional, but it can bring in new clients and convey important information to site visitors. Web hosting is an important part of your website, but how much should you pay for it, and is free web hosting ever a good idea?

 

 

 

Free Web Hosting – You Get What You Pay For

Free web hosting companies might seem like a great idea at first. After all, what could be more cost effective than not paying anything? However, free web hosting is rarely a good idea. For one thing, the customer service is usually quite poor at companies that offer free hosting. If there is an issue with your website, you need to know that your web hosting company is doing everything possible to get your website back on its feet so your customers aren’t kept waiting. With free web hosting, you can often be left waiting for up to 48 hours or longer for a response. Not only that, but since nothing is truly free, your website will likely be paid for by advertisements over which you have no control. As a website owner, you need to be able to have control over the content on your site, and not being able to have control over ads on your page is a very concerning situation.

 

How Much is Too Much?

As anyone who has searched for web hosting likely knows, the range of prices is very large. Web hosting can be purchased at prices from 3 dollars a month to several hundred per month, so how can you know the range that is right for you and will afford you the best quality at the same time? If you own a small business, you can usually get away with web hosting in the $7 to $15 per month range. This range should offer you a beautiful website with many features that will make it easy for your customers to use, as well. Additionally, this price range will usually provide you with outstanding customer service, as well. Of course, if you’re looking for extremely customized features or on-call customer support, you can look at higher price ranges, but if you’re just starting out this range should provide you with very adequate features and service.

Which Features Are Essential?

There are two things you should not, under any circumstances, skimp on: bandwidth and storage space. Bandwidth relates to how much traffic your website can take and how well it will hold up when a lot of people are using it. Also, it relates to how well your videos and other media will play. Storage relates to how much information you can store on your site, like media, text, documents, links, and more. Make sure you have more than enough of each of these. Unlimited options are the best.

You’ll also want to make sure that you can host media, like videos and photos, and if you are going to be keeping a blog, try to find hosting that includes a blog on your site. Having an on-site blog is extremely beneficial because you can send your customers to one place for all the information they need. A shopping cart is also essential for e-commerce sites.

Good to learn different web hosting companies function differently, so you’ll want to make sure that your hosting company is able to keep up with your demands. Whether you need an in-depth e-commerce site, or simply want to run a basic blog or information site, make sure you have control over the options that matter to you.

Marine Growth Prevention Systems and Why Your Ship Should Get One

If you own a private yacht, or a fishing trawler, or any sort of water craft, you ought to be well aware of one of the most prevalent hazards that can befall a seagoing vessel: Biofouling. Biofouling, as its name suggests, is the corrosion and decay that can befall the internal workings of a boat or ship from the unchecked accumulation of such marine organisms as mollusks, sponges, algae and sea slime.

 

What Is A Marine Growth Prevention System?

The purpose of a Marine Growth Prevention System is to prevent biofouling from overtaking and completely ruining the piping system of your vessel. It is used primarily in seawater cooling systems, but has applications all throughout the workings of a boat or ship. It is also frequently used in such stationary systems as oil platforms and power stations that are located directly on the water.

Why Is Biofouling Such A Dangerous Issue?

Piping systems that are of critical importance to the well being of a vessel can be overgrown and completely destroyed by the gradual, unchecked encrustation of marine organisms. They can cause a complete power failure, or wreck the internal piping system of a ship.

Biofouling is such a dangerous issue primarily because the corrosion is caused by live organisms, rather than simple rust or decay due to aging. Because the accumulation of these organisms is guaranteed to proceed apace with no limit besides the one that humans set for them, it is particularly important to be aware of the danger they can cause.

How Does A Marine Growth Prevention System Operate?

A Marine Growth Prevention System will normally be made of copper and aluminum anodes. These anodes will be placed as close as possible to the point where seawater intake occurs. These anodes will be connected to a master control panel. This panel will control the amount of current which is passed to each anode.

Switching on the control panel will produce a steady current of ions, which are then carried through the system by incoming seawater. This stream of ions will carry all through the piping of the vessel and slowly but surely result in an environment which is hostile to the sea creatures which are colonizing there.

The end result is that any organisms that enter into the piping will not wish to stay there. The atmosphere of ions within the piping will be so hostile that these organisms will prefer to pass straight through the piping and out the other side.

 

 

How To Tell If Your Ship Requires This System?

All motor operated vessels that spend a significant amount of time out on the water, especially in salt water, will need to be equipped with a Marine Growth Prevention System. If you have invested in a pleasure yacht or a fishing boat, you will do well to protect that investment. A Marine Growth Prevention System is an excellent way to keep your vessel in optimum condition. Persons interested in more information can learn more here.

The Environmental Dangers of Plastic

There is no escaping the reality that plastic waste is an enormous environmental problem both in the United States and worldwide. The United Nations Environmental Programme estimates that global plastic consumption has increased twenty-fold over the last 60 years, from 5.5 million tons in the 1950s to 110 million tons in 2009. From plastic water bottles to high grade plastic boxes used for packaging, electronics, food and household storage, our collective reliance on plastic has created a disposal problem that is overwhelming the world’s landfills, polluting its oceans, and creating tons of hazardous waste.

 

the_dangers_of_plastic_bags19

 

Although plastic disposal is a global problem, the United States leads the way in generating plastic trash. Americans throw away nearly 35 million tons of plastic every year, including about 29 billion water bottles, only about 13 percent of which makes it into the recycling stream or is burned for electricity or fuel. The rest winds up in landfills, or worse, on the ocean’s floor. The National Defense Resource Council estimates that plastic accounts for 60 to 80 percent of marine litter — about 100 million tons of it — and poisons millions of aquatic animals and birds every year. On Midway Island, 40 percent of the 500,000 albatross chicks that are hatched each year die, largely as a result of being fed plastic by their parents, who mistake it for food. Millions more marine animals die from becoming entangled in six-pack packaging or other plastic debris.

Unfortunately, the plastic that makes it into landfills is no less hazardous. Since most of the plastic currently in use is photodegradable (versus biodegradable), it never truly disappears. Photodegradation causes the plastic to disintegrate into smaller and smaller particles called nurldes or mermaid tears. Not only do these particles never completely disappear, they have a unique ability to absorb toxins from their environment, turning them into tiny toxic time-machines that can contaminate the soil and groundwater for hundreds of years. Moreover, plastics themselves contain toxic chemicals such as phthalates and BPA, both of which have been shown to cause reproductive harm. These chemicals, too, leach into soil and groundwater as the plastic sits in landfills and slowly breaks down over 100s of years.

 

Polluted with plastic debris

 

So, what is the answer? Obviously, recycling is an easy, but apparently futile solution, since Americans and our neighbors abroad do not seem to care enough about the future of the planet to be bothered rinsing, separating or otherwise properly disposing of recyclable waste. At one time, biodegradable plastic was thought to offer promise. However, according to a recent study by Germany’s Federal Environment Agency, biodegradable plastic is no better than traditional plastic once it makes its way into a landfill. In fact, about 60 percent of so-called biodegradable products undergo very little in the way of decomposition in the air and water-tight environment of landfills, reports Canada’s Environment and Plastics Industry Council. What’s more, according to archeologist William Rathje, author of the book “Rubbish!: The Archaeology of Garbage,” if the millions of tons of plastic currently in landfills around the world were to biodegrade, the resulting release of carbon dioxide and methane gasses into the atmosphere would greatly exacerbate the already catastrophic impact of global climate change.

 

To match feature USA-ENVIRONMENT/PLASTICBAGS

 

 

All this notwithstanding, the problem of plastic waste is not insurmountable. According to a 2011 study conducted by the Earth Institute’s Earth Engineering Center, the energy contained in the plastic waste in U.S. landfills is equivalent to 36.7 million tons of coal, 139 million barrels of oil or 783 billion cubic feet of natural gas. Moreover, the technology exists today to put that latent energy to use. Agilyx, a company based in Oregon, produces systems that convert plastic into synthetic crude oil, which can be refined into gasoline, diesel or jet fuel. A similar company, Pennsylvania based- EcoClean Inc. burns waste plastic to create energy for boilers and other manufacturing processes that use steam. Unlike old-fashioned incinerators, these waste-to-energy plants are designed for complete combustion, which translates into “less environmental impact than almost any other source of electricity,” says the U.S. Environmental Protection Agency. What’s more, the energy produced by burning what is currently in U.S. landfills could potentially create enough electricity to power over 16 million U.S household and reduce coal use by 108 million tons.

 

Plastic Pollution

 

Of course, the most important and most eco-friendly way to manage environmental pollution from plastic is to decrease use, but the American public seems firmly entrenched in its cultural bias towards plastic of all kinds. From water bottles to coffee cups, plastic is as American as mom and apple pie. So, for now, it appears that those who want to protect the environment from plastic pollution must be satisfied with speaking up, speaking out, and doing what they can to minimize the damage caused by those who simply don’t care.

5 Virtual Private Server Money-Saving Tips

A virtual private server allows a business owner to host his or her website. Of course, most people do not use a VPS as they feel it is too expensive for their needs. However, there are several reasons why a person should use a VPS to host their professional website. Here are five tips, for a person looking to get the most out of their hosting package.

 

 

 

$ BEST COMPANY

When choosing a host, a shopper should not choose the first company that offers the needed services. In fact, when choosing a host, one should search around as there are some bad companies and some good ones. To find the best, it is necessary to read the fine print and do research on every business. When one can find the best virtual private server (VPS) company, they will enjoy the best service.

 

$ YEARLY HOST

Most companies will give a serious discount when an individual pays for a year or two in advance. While some do not like the initial cost, it can cut the cost enough to justify the outlay of cash at one time. Most major hosts will offer, at minimum, a ten percent discount for hosting services when the customer pays for a year at a time. This will allow an entrepreneur to spend his or her money wisely and still enjoy a reliable VPS hosting experience.

 

$ SPEED

While all major VPS hosting companies offer a person plenty of speed, it is necessary to verify before signing any paperwork. While some offer promises, it is wise to search around and verify this information. Remember, with a slow website, one will scare off visitors and lose customers. Furthermore, slow-loading pages will hurt the business in the local SEO results.

 

$ INCLUDED

When paying for a VPS, one should verify what the company includes. Now, most offer free email, support and tools. If this is not the case, a business owner should verify the added costs as it is difficult to host a website without these tools. Ideally, when comparing quotes, one should look at the actual full cost as it can rise quickly when a person must pay for email or other add-ons.

 

$ CONTROL PANEL

When using any host, one will have a control panel where they can log in and make small changes. Most companies offer an easy to use interface and a trained expert should have no problem making minor changes to the website. However, a business owner should ask the Web host if they provide a simple interface to make changes. If this is not the case, a small business owner should consider taking his or her business elsewhere as a control panel will make it easy to conduct small changes.

 

When keeping these five things in mind, one can get the most out of their new VPS host. In fact, if one does not follow these tips, they will spend too much money and not get the best services for their business.

Sacrificial Anodes for Cathodic Protection

Cathodic Protection is a method expended to regulate the erosion of a metal surface by making it the cathode of an electrochemical cell. Sacrificial anodes are exceedingly active metals that are spent to avoid a less active material surface from disintegrating. Sacrificial anodes are made from a metal compound with a more deleterious electrochemical capacity than the other metal it will be used to guard. The sacrificial anode will be expended instead of the metal it is shielding, which is why it is represented as a “sacrificial” anode.

 

The matters utilized for sacrificial anodes are either moderately uncontaminated active metal, for example a ZINC Sacrificial Anode or magnesium, or are magnesium or aluminum composites that have been precisely formed for use as sacrificial anodes. In treatments where the anodes are concealed, a distinct back-fill substance encases the anode so as to certify that the anode will yield the anticipated production.

 

As the sacrificial anode functions by presenting another metal exterior with a more deleterious electronegative and considerably more anodic surface, the flux will stream from the recently presented anode and the sheltered metal becomes cathodic, producing a galvanic cell. The corrosion effects are transported from the metal exterior to the galvanic anode and will be forfeited in support of the sheltered metal construction.

For edifices such as elongated conduits, where inert galvanic cathodic defense is not satisfactory, and outer DC electrical power source is utilized to deliver satisfactory current.

Cathodic defense systems guard an extensive array of metal constructions in numerous settings. Customary uses are:

  • Steel water or fuel conduits
  • Storage tanks, for example domestic water heaters
  • Steel dock piers
  • Ship and boat structures
  • Offshore oil boards
  • Onshore oil well coverings
  • Metal support bars in concrete structures and edifices
  • Galvanized steel, in which a sacrificial covering of zinc on steel parts shields them from corrosion

In certain situations, cathodic defense can avert stress erosion splitting.

Though there are several linear differences on how a cathodic defense system can be connected, there are merely two straightforward approaches to utilizing cathodic defense.

1. Sacrificial anode cathodic fortification (connecting galvanic anodes)
2. Impressed current cathodic defense (connecting repaired anodes)

 

 

Sacrificial Anode Types

Sacrificial Anode Types

 

 

Useful Advantages of Utilizing Cathodic Defense

  • Decrease in the price of set-up erosion
  • Decrease in structure catastrophes
  • Decrease in product loss due to corrosion
  • Reduction in interruption for emergency upkeep
  • Escalated structure service existence
  • Augmented level of substructure service to clients
  • Improved well-being and refuge to submerged substructure

Once assembly of a new submerged or immersed system is being intended, corrosiveness of the atmosphere must be deliberated as one of the issues in the planning of the structure. If understanding with comparable systems in the locality of the construction location has revealed that the site situations are destructive centered on leakage and malfunction accounts, cathodic defense must be deemed as a way to limit rust on the new structure.

Cathodic defense is one of the limited approaches of erosion regulation that can be successfully used to regulate deterioration of current suppressed immersed metal exteriors.

Singapore: The Pacific’s Cloud Host

The cloud storage and computing age has only recently begun to rise to acknowledgment. It was over the last 5 years the cloud storage has become popular. Cloud storage allows you to hold an indefinite amount of files in a server that specializes in storing data. The data can then be accessed from any computer as long as you have log in credentials and an Internet connection. It only makes sense to use a local server due to the possibility of slower download speed from farther servers.

Choosing a server that is near the destination where you will be primarily is important, therefore you should choose the closest available server to you. Cloud hosting in Singapore is among the fastest in the pacific. They have a great Internet infrastructure that allows you to quickly transfer your files. In the pacific region, cloud in Asia is relatively sparsely populated compared to the rest of the world. It is hard to find good a good cloud service in the area.

By using Singapore servers, you will have a good median travel route when abroad. If you frequently visit the Pacific regions, Cloud Hosting in Singapore is a great median server. It will serve you well in the majority of areas in the pacific that you may travel to. This is the primary objective of cloud hosting. The goal is to have access to server that will be the shortest among all of your destinations. Cloud in Asia’s mainland may not be the most productive server as compared to Singapore. For example, if you visit the western coast of the United States for business, you would not have an optimal route as opposed to Singapore. Therefore, you would be waiting longer to download your files to your personal computer.

Asia’s Cloud service has come a long way over the recent years. It is now as fast as other cloud services, and will provide better service than others provided that you are a resident of the Pacific.

Arabic Content a Key Growth Segment in the Middle East

There is a consensus among experts working in the information and communications technology (ICT) industry that the strong latent demand for Arabic content in the Middle East will create new business opportunities for digital entrepreneurs in the coming years. Overall, Arabic content (e.g., text, audio, video, images) is estimated to account for less than one percent of total content on the internet; yet, Arabic speaking people currently represent more than five percent of the world’s total population.

According to figures from Oxford Business Group, in 2010 about 75 percent of all Arabic content was hosted by three major portals: Maktoob, d1g and Jeeran. Although these major players still dominate the market, a number of Arabic-content startups have been sprouting up in countries like Jordan, where the ICT sector has grown by around 25 percent per year over the past decade. In addition, the country’s capital, Amman, was recently named one of the world’s top ten cities for internet startups, as determined by the availability of skilled human resources, the strength of ICT infrastructure, the incidence of entrepreneurship and the efficiency of the regulatory environment for businesses. Indeed, Maktoob itself was born in Jordan’s hospitable ICT business climate, though the company was acquired by Yahoo! In 2009 at a cost of 164 million dollars.

Despite positive indicators, the overall outlook for Arabic content in the Middle East is mixed because, at the regional level, the ICT sector suffers from a number of weaknesses. As noted by Ari Kesisoglu, the Managing Director of Google Middle East and North Africa in an interview with regional press, “There are three main challenges we face in the region. First, in some countries the cost of getting access to the internet is high. Second, we need more content in Arabic. And the third challenge is that e-commerce in the region has not realised its potential. SMEs need to create websites and we need more businesses in the Arab world to realise the economic impact of the internet.”

As reflected in such statements, the issues affecting Arabic content also affect the region’s entire digital ecosystem. This means that development planners must take a multi-pronged approach to promoting Arabic content growth, one that not only focuses on reducing costs and increasing the use of e-commerce, but also on areas like education, where more should be done to create new workers with strong ICT skills.

What is more, both governments and private investors in the region must ensure that creators of Arabic content have the venture capital funding they need to start new enterprises. In this respect, Jordan is once again a strong performer, particularly in light of the activities of Oasis 500 – an angel investment outfit based in Amman that supports new digital companies. Over the past few years, Oasis 500 has supported countless ICT firms in the country focused specifically on high quality content in the Arabic language.

Ultimately, if the Middle East can produce more Arabic-language content creators, it will see an increase in the use of social media sites like Facebook and Twitter. In turn, this will further empower the public, and present local businesses with more opportunities to target customers in the digital space. Growth in Arabic content would also have profound implications for the region’s media and advertising sector.

Stay updated with more recognised and respected source of business intelligence in many parts of the world from the Oxford Business Group Twitter.

While Arabic content quality is improving, says Najeeb Jarrar, the MENA Product Marketing Manager at Google, the difficulty now is that several content silos are occurring in the Arab World, by country. Watch this video about the Mobile vs. Internet vs. TV: Who Wins in the Arab World?
