PPH storage tank The tank body is extruded into a tank body by spiral winding equipment. What are the main winding process?
1. The system adopts the process of hot-melt polypropylene or polyethylene terephthalate particles, extruding them, and then winding them into cans on the steel mold. Advantages: the production efficiency is 5-8 times higher than that of manual production, with no joints and good integrity, corrosion resistance and leakage resistance. It can make the top of the tank body thinner and the bottom thicker, so that its price can be reduced. Product size and shape are not limited. PPH storage tank is made of granular materials with good aging resistance.
2. External welding is a process that uses imported automatic extrusion welding units to realize one-time welding of large welds at the position of high tank stress. Hot melt new PPH granular materials with the same performance as the tank body at the large weld, and integrate them with the bottom and the tank body of the PPH tank.
3. The internal welding of PPH storage tank is an automatic long arm extrusion welding process, which is an important step in all processes. PPH granular material with the same performance as the tank body is hot melted at the internal weld seam and integrated with the tank bottom and tank body. The principle is the same as external welding, but the equipment is different. Internal welding process features: highly mechanized and automated, its quality is very stable. The weld specification can be designed according to the stress characteristics of the product to give full play to the integrity of the weld. The product has good integrity. The weld is integrated with the substrate, and has good corrosion resistance and leakage resistance. It can reduce flash, and the seam is smooth and beautiful.
4. The nozzle installation is the next process, which is equivalent to the bottom welding of the reduced version, that is, use the imported small automatic extrusion welding unit to weld the connecting pipe and flange, then use the hole opener to cut the diameter of the corresponding PPH tank body, and then use the German handheld extrusion welding. Characteristics of nozzle installation process: highly mechanized and automated, product quality is stable. The nozzle weld is integrated with the tank body, and its welding strength is high. It can reduce flash, and the weld is smooth and beautiful. PPH storage tank
