Proper venting of polyethylene chemical storage tanks is vital for safe operation. It is also critical to 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 chemical tanks. During pneumatic offloading from a tanker truck, offloading pressures can exceed 30 psi, resulting in high ACFM rates. Under this scenario, standard venting designs are inadequate to release the pressure. To protect against an over pressurized chemical storage tank you should consider one of our innovative tank vent lid solutions.
Polyethylene chemical storage tanks require the correct installation for two essential reasons. First, venting ensures the safe operation of the tank and the chemicals stored under pressure within the tank. Secondly, proper installation is vital to maximize the life of the chemical storage tank.
