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 ℃.

Comparison of PPH mixing tank price and PP mixing tank and maintenance measures. It is necessary to use electric heating to melt and extrude the particles onto the steel mold, which consumes a lot of power. The PP storage tank only has the power of the welding gun, so it consumes less power; The raw material of PPH mixing tank is PPH granular material, and the raw material of PP storage tank is polypropylene plate. The price of PPH granular material is more expensive than polypropylene plate; Cooling and demoulding are required, which are performed by electric device, but not for PP storage tank; Steel molds are required for processing, and natural gas is required for preheating before processing. The startup cost is high, and PP storage tank is directly rolled into a tank with polypropylene plates, so the cost is low; The PPH mixing tank is welded with a large extrusion electric heating drag gun, which consumes a lot of power. The PP storage tank uses a small manual drag gun, which consumes less power.

The key manufacturing method used in the production of PPH storage tank is one-time forming coiling manufacturing method, so it is simple in structure. The application of PPH storage tank is relatively convenient due to its simple construction. When the rubber bearing is a plastic rubber bearing, the compressive strength, stiffness, service life and total number of manufacturing shall be considered. When the rubber bearing is a metal rubber bearing, the other standards shall be the same as 1. In addition, the surface of metal rubber bearing shall be corrosion resistant. When the rubber bearing is a concrete rubber bearing, the concrete rubber bearing of the first horizontal tank shall consider the compression strength provisions, and the total number of rubber bearings shall be 2. When there are several rubber bearings, their design elevation shall be the same, and there is no need for uneven ground settlement, and the bottom shall be basically flat.

The raw material of PPH mixing tank is PPH granular material, and the raw material of PP storage tank is polypropylene plate. The price of PPH granular material is more expensive than polypropylene plate; The processing of PPH mixing tank requires the use of steel molds.

The PP storage tank is directly rolled into a tank with polypropylene plates, which costs little; The PPH mixing tank needs to use electric heating to melt and extrude the particles onto the steel mold, which consumes a lot of power. The PP storage tank only has the power of the welding gun, which consumes less power; The PPH mixing tank needs to be cooled and then demoulded, which are all performed by electric devices, but not the PP storage tank; The PPH mixing tank is welded with a large extrusion electric heating gun, which consumes a lot of power. The PP storage tank is welded with a small manual gun, which consumes less power; Others, such as steel mold replacement, equipment land occupation and equipment maintenance, are not required for PP storage tanks.

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 the process of using PPH spiral extrusion winding unit to process PPH granules into can 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 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.
