The reason why the price of PPH storage tank is higher than that of PP storage tank. The production process is different. PP storage tank is a kind of storage tank made by welding polypropylene plates, while PPH storage tank is made by processing PPH particles after physical treatment. The raw materials are different. The raw material of PPH storage tank is PPH granular material, and the raw material of PP storage tank is polypropylene plate. The cost of PPH granular material is higher than that of polypropylene plate; Due to different processing equipment, PPH storage tank needs to use steel mold for processing, and it needs to use natural gas for preheating before processing. The startup cost is high, and PP storage tank directly uses polypropylene plate to enter the tank, so the cost is low; The power consumption is different. The PPH storage tank needs to use electric heating to melt the granular materials out of the steel mold. The power consumption is large. The PP storage tank is only the welding gun of the electric welding point, and the power consumption is small; PPH storage tank needs to be cooled and then demoulded, which is carried out through electrical equipment rather than PP storage tank; PPH storage tank is welded with extrusion type large electric heating traction gun, which has high power consumption. PP storage tank is welded with manual small traction gun, which has low power consumption; The labor cost is different. PPH storage tank has less labor than PP storage tank, which is why many plastic storage tank manufacturers hope to develop PPH storage tank.

PPH tank body extrusion winding production tank body butt welding is the process of using PPH spiral extrusion winding unit to process PPH particles into tank body molding. 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 is 5-8 times higher than that of manual production. The product has good integrity, no seams, good corrosion resistance, good leakage resistance, flat and beautiful product, thin tank body and thick tank body, low price, unlimited product size and shape, and the product is processed with granular materials, with good anti-aging performance. Polypropylene tank itself has the advantage of internal and external anti-corrosion, so it can be stored in some highly corrosive environments. Because linear polyethylene is used, it has good service performance, and the special structure of polypropylene rolling tank is used, so the service life can basically reach more than 15 years. In addition, it can be used under normal atmospheric temperature and pressure when it is stored.

Why can PPH storage tank replace stainless steel? The comparison of two kinds of dangerous chemical storage tanks is made from the aspects of mechanical strength, service life, corrosion parameters, maintenance, service temperature, etc. The service life of PPH storage tank is usually 8-10 years, while that of stainless steel storage tank is 10-13 years more; The mechanical strength of stainless steel storage tank is higher than that of PPH storage tank, but hazardous chemicals storage tank is generally placed statically, instead of storage tank with high mechanical strength; PPH storage tank is resistant to most acids, alkalis, organics and mixed liquids. As long as the service temperature is within the limited range, there will be no corrosion. Many media that PPH storage tank can resist will corrode stainless steel (except special stainless steel); In terms of maintenance, PPH storage tank is simple in maintenance and tools, which can be handled by the manufacturer; The service temperature of dangerous chemicals is generally normal temperature, and the high service temperature of PPH storage tank z can reach 100 ℃.

When the storage tank made of polyethylene is produced and processed again, it does not need to use traditional welding, so its volume will be larger when it carries liquid. Because the HDPE storage tank does not need to be welded, so there is no weld. When it is used again, it does not need to worry about instability due to too much carrying liquid. Generally speaking, most storage tanks have a stability coefficient. The reason why the stability performance of storage tanks is different is that the performance of raw materials used is different. If the materials used are poor, even if the process is good, the stability performance is not guaranteed. When selecting raw materials for storage tanks, the first thing we should do is to check the quality certificate and inspection report of the raw materials. After checking, all data can be put into production only if they meet the standards. Besides, plates are used at the top and bottom of the tank, so there are requirements for plates.
