Polypropylene storage tank PPH storage tank forming process using spiral extrusion winding technology, the main processes are tank extrusion winding, external welding, internal seam welding, pipe mouth installation.


First, tank extrusion winding production


Polypropylene storage tank body collision welding is a process in which PPH particles are processed into tank body by PPH spiral extrusion winding unit. The system adopts the process of hot melting and extruding PPH particles and then winding them into tanks on steel molds.


PPH winding storage tank, polypropylene storage tank extrusion winding advantages:


◆ Production efficiency is 5-8 times higher than manual


◆ Good integrity, no seams, corrosion resistance, leakage resistance


◆ The product is smooth and beautiful, and the tank body is thin on the top and thick on the bottom, reducing the price


◆ Product size, shape is not limited


◆ The product is made of granular material and has good anti-aging performance

Second, external welding production

The external welding of polypropylene storage tank is a process in which the imported automatic extrusion welding unit is used to make the large weld forming at the most stressed part of the storage tank. The new PPH particles with the same properties as the tank are hot melted in the large weld, and the tank bottom and tank body are integrated.

Process features:

◆ High degree of mechanization and automation, stable product quality


◆ Weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld


◆ Good product integrity, weld and matrix integration, corrosion resistance, leakage resistance


◆ Can reduce flash, smooth and beautiful joints


◆ Add UV absorbent to PPH granules to prevent aging and extend service life.

Third, internal welding production


The internal welding of polypropylene storage tank is an automatic long arm extrusion welding process, which is a key step in all processes. The new PPH particle material with the same nature as the tank is hot melted in the internal weld, and the bottom of the tank and the tank are integrated, the principle is the same as the external welding, but the equipment is different.


Process features:


◆ High degree of mechanization and automation, stable product quality


◆ Weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld


◆ Good product integrity, weld and matrix integration, corrosion resistance, leakage resistance


◆ Can reduce flash, smooth and beautiful joints


◆ Add UV absorbent to PPH granules to prevent aging and extend service life.

Four, pipe mouth installation and production


The installation of the pipe opening of the polypropylene storage tank is the last process, which is equivalent to the reduced version of the bottom welding, which is to use the imported small automatic extrusion welding unit, weld the nozzle and flange, and then use the hole opener to open the diameter of the corresponding size on the tank, and finally use the German MUNSCH portable extrusion welding.


Process features:


◆ High degree of mechanization and automation, stable product quality


◆ Pipe weld and tank body integrated, high welding strength


◆ Can reduce flash, smooth and beautiful weld


◆ Adding ultraviolet absorbent to polypropylene granules prolongs service life.
