PPH winding tank is a plastic tank with good development prospects at present. Its advantage is that the change of processing technology makes it outstanding in the tank. PPH storage tank body uses PPH particulate raw materials to melt with a screw extruder, and then the molten extrusion raw materials produce the tank body on the grinding tool. After a certain level of temperature is reduced, the molding can ensure the integrity of the tank body. Internal welding process features: high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product, 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 anti-corrosion means of PPH storage tank are cathodic protection and coating protection. Coating protection can be divided into two ways, namely, internal anti-corrosion treatment and external anti-corrosion treatment of PPH storage tank. For oil storage or product oil storage tanks, the required performance of anti-corrosion coating in the tank is electrostatic conduction. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is to combine the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH tank, the temperature resistance characteristics between anti-corrosion coatings must be considered, which is interchangeable. In the alkyd anti-corrosion coating, direct combination use must be avoided. This is because of chemical reaction with zinc powder. Cathodic corrosion protection of storage tank includes impressed current cathodic protection of storage tank bottom plate and protection treatment of storage tank ponding layer anode. Cathodic corrosion protection of storage tank is divided into impressed current cathodic protection on the outside of the bottom plate of the storage tank, and protective treatment on the anode of the ponding layer in the tank.

The main contents of cleaning the HDPE storage tank are as follows: at the end of each manufacturing, clean the surface of the HDPE container with fingers, and continuously clean the outside of the mechanical equipment with a large amount of water. Damage to the thermal insulation layer is strictly prohibited. According to the processing technology, the solution can be cleaned after a certain period of time. For a long time, more than 72 hours, machines and equipment should be cleaned again before class. It is forbidden to enter acid liquor into the bobbin of this commodity. If the cleaning box requires acid, do not use acid with pH<2. Once the acid enters the casing of this mechanical equipment, hydrogen effect will occur, and the surface will fall like a fish scale on a large scale. The general cleaning cylinder uses 2% of sodium hypochlorite solution and uses tap water to clean the cylinder. The HDPE tank shall be cleaned according to the requirements of Chinese standards. When entering the machine and equipment for cleaning, the water bottle should be padded at the bottom of the sponge pad to prevent special tools from falling in. Wear rubber shoes to prevent damage to the laminated glass. To sort out the actual staff, the records must be sorted out immediately to determine the work experience and the inspection and signature of the project.

Welding technology of PPH storage tank. In terms of automatic welding equipment and welding materials for large storage tanks, the degree of localization is not high enough, especially the automatic welding wire matching the imported high-strength steel plate, which still depends on imports and has high prices. This is a problem that China's PPH storage tank manufacturers must solve in the future; The research and application history of submerged arc automatic transverse welding for flip chip storage tank is not long, and there are still many problems to be solved; There is no doubt that CO2 semi-automatic gas shielded welding technology has obvious advantages over traditional shielded metal arc welding, but there are still many problems to be solved if this method is to be widely popularized and applied outdoors. First, the auxiliary equipment should be portable and flexible, and the wiring should have sufficient length. According to different weldments or parts, corresponding wind proof auxiliary devices shall be developed. It can be predicted that the development trend of welding technology of pph tank manufacturers will have a good application prospect in the welding fields such as petrochemical industry; Gas shielded welding with flux cored wire will be the development direction of large pph tank manufacturers. In the welding of low-temperature storage tank, automatic welding is beneficial to ensure the stability of low-temperature impact performance of heat affected zone.

PPH mixing tank is made by seamless extrusion winding technology. Pipe orifice, inner weld and outer weld are all processed by automatic extrusion unit equipment, which is superior, stronger and lower than plastic tanks made by traditional technology. 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 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. PPH reaction kettle uses PPH spiral extrusion and winding unit to process PPH granules into tank body forming process. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. PPH reaction kettle has the characteristics of good integrity, uniform thickness, corrosion resistance, seamless, aging resistance and good leakage resistance.
