PPH storage tank It integrates design, manufacturing and installation, and adopts PPH spiral extrusion winding technology.
The forming process of PPH storage tank adopts spiral extrusion winding technology with reliable quality. The main processes include tank extrusion winding, external welding, internal seam welding, pipe orifice installation, etc.
Can body extrusion winding is a process that uses PPH spiral extrusion winding unit to process PPH granules into a can body. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency of this process is about 5-8 times higher than that of manual process, and the product is flat and beautiful, with good integrity, no joints, good corrosion resistance and leakage resistance. The tank body is thin at the top and thick at the bottom, and the size and shape of the product are not limited.
External welding is the process of using the imported automatic extrusion welding unit to make the large weld of the tank with large stress be welded in one time. 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 process features high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld, reduce flash, and make the joint smooth and beautiful. In addition, the ultraviolet absorber is added to PPH granular material to resist aging and extend the service life.
Internal welding is an important step in the process of automatic long arm extrusion welding. The PPH granular material with the same nature as the tank body is hot melted at the internal weld seam, and is integrated with the tank bottom and tank body. The principle is the same as that of external welding, but its equipment is different.
