On the surface, polyethylene storage tanks can look pretty similar. It isn’t easy to tell a well-designed and constructed tank from a cheap, inferior tank. Many customers don’t realize that there’s a standard for tank construction based on resin properties and testing. Others simply assume all tank manufacturers follow the ASTM D 1998 standards. ASTM standards require that all polyethylene tanks and tank materials go through three tests to determine the strength and structural integrity of the chemical storage tank. There is also an additional test for cross-linked polyethylene tanks to measure the chemical makeup of the tank materials. Together, these standardized tests help ensure that you have the strongest, most durable chemical storage tank available.

For many industries and facilities, oxygen is bad news for some chemicals stored in tank systems. Often, when the storage material comes in contact with oxygen, the substance oxidizes and degrades, or it can dry out. In any scenario, coming into contact with oxygen means you’ve lost product — which translates to less revenue and costs of replacement. Tank blanketing helps prevent contact with oxygen, and Poly Processing is your partner for protecting your stored materials.

Commercial sodium hypochlorite is the product of chlorine and sodium hydroxide. It is typically supplied as a liquid solution with a concentration of about 12%. Although the liquid solution is more expensive than gas, it has a lower health risk, it’s easier and safer to use, and it reduces the risk of releasing chlorine gas — especially in areas that are close to surrounding properties.

PolyGard™ is a seamless, corrosive-resistant polyethylene lining system for steel tanks and vessels. It’s used as a barrier to protect the steel from the aggressive chemicals you’re storing—even in the harshest of conditions. PolyGard lets you combine the chemical resistance of polyethylene with the durability and strength of stainless steel. To truly understand how effective PolyGard is, let’s examine what it is comprised of, how it is made, and how it is commonly used.

One of the most important design considerations of any chemical storage tank system is the use of flexible connectors and isolation valves. When paired correctly, these accessories will not only help ensure your storage tank’s longevity, they can also protect the tank from hinge points that cause dangerous leaks.

When it comes to choosing a chemical storage solution, you won’t find a more aesthetic option than stainless steel tanks. Steel tanks are popular in breweries and other applications where they’re on public display. The tanks look shiny and clean, and they contribute to the interior design of the space. Steel tanks also have a reputation for being one of the most reliable chemical storage systems on the market.
