The can body is extruded into the forming process of the can body by the spiral winding device. In this system, PP or PPH particles are extruded after hot melting, and then wrapped in the tank on the steel mold. PPH winding tank

Advantages of extrusion winding:

The production efficiency is generally 5-8 times higher than manual work.

Good integrity, no joints, corrosion resistance and leakage resistance.

Smooth and beautiful, the tank is thin and thick, and the price is friendly to people.

The size and shape are not limited.

It is made of granular materials and has good aging resistance.

External welding production

External welding is the welding process of large welding seam by using imported automatic extrusion welding machine to make the part of storage tank with high stress. The new PPH particles with the same performance as the tank body are hot melted at the large weld, and the tank bottom is integrated with the tank body.

Backwelding process characteristics:

High degree of mechanization and automation, and stable product quality.

The weld specifications can be designed according to the mechanical characteristics of the product, so as to give play to the integrity of the weld.

The product has good integrity, the weld is integrated with the base metal, and has good corrosion resistance and leakage resistance.

It can reduce wrinkles, and the joints are smooth and beautiful.

Internal welding production

Internal welding is an important step in all processes, and automatic long arm extrusion welding process is adopted. A new type of PPH particles with the same performance are hot-melt welded inside the tank body and integrated with the tank bottom and tank body. The principle is the same as that of external welding, but the equipment is different. PPH storage tank

Internal welding process characteristics:

High degree of mechanization and automation, and stable product quality.

The weld specifications can be designed according to the mechanical characteristics of the product, so as to give play to the integrity of the weld.

The product has good integrity, the weld is integrated with the base metal, and has good corrosion resistance and leakage resistance.

It can reduce wrinkles, and the joints are smooth and beautiful.

Installation and fabrication of nozzle

The nozzle installation is a process before the end, which is equivalent to the bottom welding of the shrink version. It uses the imported small automatic extrusion welding machine to weld the pipe and flange, then use the hole opener to open the corresponding diameter on the tank body, and then use the hand-held extrusion welding.
