Poly Processing works diligently to produce each and every chemical storage tank built to spec. But if a tank isn’t installed correctly it could lead to damage, leaks, safety issues for personnel, and a shorter tank life. Everyone should take chemical tank installation seriously.

Before you purchase a chemical storage tank, it’s important to know what kind of service you can expect from the manufacturer — immediately and for years to come. You might have installation and startup needs, but you may also have questions about retrofitting a tank or installing new tanks. 

Many tank manufacturers don’t have a field service team or service department. They may hire a local fix-it professional who isn’t familiar with their storage systems, or you may have to find a service technician yourself. Poly Processing has our own nationwide field service team that can service your PPC chemical storage tank at your facility.

Whether you're storing dangerous chemicals or common food-grade materials, reliability is one of the most important factors to consider when purchasing a tank. 

How do you know when it’s time to replace your polyethylene storage tank, instead of repairing it? No matter what chemical tank manufacturer you use, there are hidden costs to replacing a damaged tank. At some point, it’s less expensive to replace the tank — but that could be years later than you might think.

Many companies only calculate the tank purchase cost and shipping costs when deciding whether to repair or replace a chemical storage tank, but there are several additional factors to consider as well. Let’s look at these overlooked factors that contribute to your total cost.

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.

Poly Processing is a leader in building innovative solutions to complex chemical storage challenges. Far beyond simple plastic tanks, we have developed a fleet of products that address specific needs of chemical storage. The result for your business is ensured safety, easy tank maintenance, and extended tank longevity.

We get a lot of questions about the standard testing on chemical storage tanks that we do at our facility. Vertical tanks larger than 500 gallons are extensively tested to ensure that they meet ASTM standards. Depending on customers’ needs, we also offer additional testing on our chemical storage tank systems.

Environmental stress cracking occurs when microscopic cracks form in polyethylene tanks as a result of storing aggressive chemicals. Over time, these imperceptible cracks combine to form larger cracks, which can lead to leaks or even tank failure. If cracks occur, it’s recommended that you replace the polyethylene tank.

Not all high-density polyethylene tanks are created equal. Although they sound nearly identical, linear polyethylene and cross-linked polyethylene (XLPE) chemical storage tanks have significant differences. Those differences could impact your organization’s bottom line, your people’s safety, and the operations of your facility.

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.
