Poly Processing's SAFE-Surge Manway Provides Greater Level of Safety

Proper venting of polyethylene chemical storage tanks is vital for safe operation — it’s also critical for maximizing a polyethylene storage tank's effective lifecycle. 

Poly Processing's chemical storage tanks are designed to function at atmospheric pressure per ASTM-D 1998, the industry standard for producing vertical polyethylene tanks. During pneumatic offloading from a tanker truck, offloading pressures can exceed 30 psi, resulting in high ACFM rates.

How to Choose the Right Manway Cover for Storage Tanks

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.

Managing Harmful Chemical Fumes

 

All chemicals stored in polyethylene tanks require some form of venting in order to keep them safely stored. However, in some cases, the harmful fumes emitted from the chemicals cannot be released directly into the atmosphere. Fuming chemicals require special considerations to reduce harmful vapors before they are evacuated. There are many important things to consider when managing harmful chemical fumes and controlling air pollution.

When You Should Choose an F.S. 2650 Manway Cover

Pneumatically-filled tanks must be properly vented to avoid offloading pressures, which increase the tank interior pressure beyond the ASTM-D 1998 regulation allowances. The right manway cover can provide the venting required to avoid this situation, but it can be difficult to know exactly which type to choose.

Handle Storage Tank Over-Pressurization: Choose the Right Manway Cover

Pneumatically filled chemical storage tanks have the potential for becoming over-pressurized. Over-pressurizing a storage tank through repeated fill cycles can damage and weaken the tank sidewalls, resulting in stress cracks and premature tank failure. Proper tank venting is needed to prevent over-pressurization.
