Installation of Yichang PPH winding tank
PPH storage tank is resistant to most acids, alkalis, organics, and mixed liquids. As long as the operating temperature is within the limited range, there will be no corrosion. Many media that PPH storage tank can resist will corrode stainless steel (special stainless steel is outside); In terms of protection, PPH storage tank is simple in protection and tools, and the manufacturer can handle it by himself; The operation temperature of dangerous chemicals is generally normal temperature, and the high operation temperature of PPH storage tank can reach 100 ℃. PPH storage tank has become a necessary equipment for chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new data, new energy, biomedicine, and even some professions have changed some stainless steel reaction kettles with normal temperature and pressure into reaction kettles made of PPH raw materials.

The internal welding of PPH storage tank is an automatic long arm extrusion welding process, which is an important step in all processes. The new 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. Internal welding process characteristics of PPH storage tank: high mechanization and automation, stable product quality; The weld specifications can be designed according to the stress characteristics of the products, so as to give full play to the integrity of the weld; The product has good integrity, the weld is integrated with the parent body, and has good corrosion resistance and leakage resistance; It can reduce flash, and the joints are smooth and beautiful. UV absorber is added to PPH granules to prevent aging and prolong service life.

The storage tank is a new spiral wound disposable product with no welding cracks and better sealing performance. The thickness of PPH storage tank is not affected by the manufacturing materials. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to make the large weld of the storage tank with high 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. Welding process characteristics of PPH storage tank bottom: high mechanization and automation, stable product quality; The weld specifications can be designed according to the stress characteristics of the products, so as to give full play to the integrity of the weld; It can reduce flash, and the joints are smooth and beautiful.

The key requirements of PPH tank design are: no danger, reliable: the data of high strength and toughness of materials, and the interchangeability structure of media should have sufficient rigidity and pressure bending performance, and the sealing performance should be good. Meet process request: function request of life request. Good comprehensive economy has high consumption efficiency, low consumption coefficient, reasonable structure, complicated manufacturing, convenient transportation and convenient equipment. Easy to operate, maintain and control: maintain and better control. Good environmental performance of PPH storage tank: At present, great progress has been made in the design scheme, engineering construction and data information of large and medium-sized storage tanks in China. However, our country still lacks experience in the design and construction of high strength data of large storage tanks. In the future, our country should strengthen the development and implementation of large storage tanks to make the production process of large storage tanks more carbon friendly.

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.
