Plastic tank is a molding, advantages of it by itself without welding seam, no leakage, non-toxic, shock resistance, corrosion resistance, to meet the health standards. Although it has many advantages, but in the factory before it needs to be detected.
So when the plastic tank just making HERSHEY'S, how to test non leakage of it? Generally start are first detected by the water injection mode, is divided into three sections namely plastic tank high 1/2, 3/4 and design highest level slow test.
Of course, when the plastic tank water filled tank, the tank bottom to observation of strength and tightness. Finally is the detection of floating roof lifting flexibility, tightness, floating ladder is stuck, and central drainage pipe flexibility and tightness etc..
When everything is examined and qualified plastic tank to the appearance of finish coating and put into use.
