Some companies need to place their chemical storage tanks underground because of space limitations, or for aesthetic reasons. Steel tanks and reinforced tanks are built to withstand the external pressure that is applied underground, but what about lightweight plastic tanks? While plastic storage tanks have many advantages over other tank materials, polyethylene is not the solution for underground storage. Here’s why.

Various types of chemical storage systems have handrails along the top of the tank, but Poly Processing tanks don’t. Polyethylene tanks can’t support handrails, and the tanks shouldn’t be walked on. The domed surface can be very slippery, and the plastic can become brittle over time and possibly crack under a person’s weight. So how do you safely inspect manways, check gauges, and service level sensors or mixers?

When building your storage tank system, it’s important to not only carefully consider the tank itself, but also the fittings and accessories. An important part of your tank is your manway cover. Failing to understand the purpose and function of the manway can threaten the safety of your employees and result in leaks, tank damage, and environmental hazards. Let’s look at three things you should consider when choosing a manway cover. We’ll also introduce the best options for each consideration.

There are several types of chlorine sources that water treatment plants can use: chlorine gas, liquid sodium hypochlorite, or onsite production. Chlorine gas can be more cost effective, but a growing number of states are converting to bulk sodium hypochlorite or bleach. If chlorine gas is more economical, why would water treatment plants convert to sodium hypochlorite?

Proper chemical storage is an important aspect of operating a plant or facility. In order to ensure that your chemicals are stored safely in polyethylene tanks, you need to choose a tank with the correct wall thickness. A fraction of an inch can make the difference between a tank that lasts for decades and one that fails early. Here’s what you need to know about determining the correct wall thickness for your chemical storage tank.
