How Mechanical Stress Causes Polyethylene Tank Cracks

In addition to chemical stress, mechanical stress can also cause polyethylene chemical storage tanks to crack. Mechanical stress occurs when the tank’s structure is compromised after a physical impact with another object, over pressurization and rigid plumbing that does not allow for natural expansion and contraction of the tank.

In this article, we'll look at factors causing mechanical stress in polyethylene storage tanks, and offer solutions to reduce the impact of mechanical stress.
