In the use of PPH storage tank, the process of reaction material mainly depends on the change of storage tank temperature to realize the reaction. When designing PPH storage tank, its pressure and temperature should be standardized. The pressure here refers to the gauge pressure unless otherwise specified. Working pressure refers to the possible high pressure at the top of the container during normal operation. Design pressure: the pressure used to determine the shell thickness at the corresponding design temperature. 1.05 times the high working pressure shall be taken for the internal pressure vessel, and the static pressure of the liquid shall be included. The design pressure of external pressure vessel shall not be less than the possible large internal and external pressure difference under normal operation; Test pressure: refers to the pressure at the top of the vessel under pressure test; The vacuum vessel is designed according to the external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is taken as the smaller value of 1.25 times the internal and external pressure difference or 0.1MPa, or 0.1MPa if there is no safety control device.

PPH mixing tank can be divided into two forms: sloping bottom and flat bottom. The corrosion resistant container with full plastic structure is made of modified polypropylene laminate, pure polypropylene or glass fiber reinforced pure polypropylene through secondary processing. Select and configure motors, reducers, mixing paddles, heating devices, etc. according to the actual situation of customers. This product is corrosion resistant, scientific in design, reasonable in structure, excellent in performance, complete in specifications and patterns, safe and reliable in use. It is mainly applicable to the reaction kettle, which is widely used in the material reaction in the production of petroleum, chemical industry, rubber, pesticide, dye, medicine, food and other industries. PPH mixing tank product description: production process: PPH reaction kettle uses PPH spiral extrusion 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. Application field: It is used in chemical industry, metallurgy, rare earth, electronics, dyes, pigments, dyes, environmental protection, pharmaceuticals, power plants, brewing and other industries.

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.

HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

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.
