Product: PPH spiral wound storage tank

PPH storage tank External welding is the process of using the imported automatic extrusion welding unit to realize the one-time welding molding of large welds at the stress parts of the storage tank. The new PPH granular material with the same property as the tank body is hot melted at the large weld seam, and is integrated with the tank bottom and tank body. The bottom process characteristics of PPH storage tank are introduced below.

Welding process characteristics of PPH storage tank bottom:

High mechanization and automation, stable product quality

The weld specifications can be designed according to the stress characteristics of the products, and the anti-corrosion storage tank can give full play to the integrity of the weld

The product has good integrity, storage tank, welding seam and parent body are integrated, corrosion resistance and leakage resistance are good

It can reduce flash, and the joints are smooth and beautiful

UV absorber is added to PPH granular materials to prevent aging. Chemical storage tanks and tanks extend the service life.
