The thickness requirements for the bottom plate and top plate of PPH storage tank, the previous welding process is to use a portable welding gun to melt the welding rod, and then weld the tank body and bottom plate together. Since the welding rod is an external accessory, it cannot guarantee the consistency of the material with the bottom plate and tank body, which has a certain impact on the quality of equipment. Using a portable welding gun to weld, it cannot achieve the same welding strength, and the weld surface is uneven, There are many hidden dangers for equipment leakage. The bottom plate and can body are welded by mechanical welding process, which can be divided into external welding and internal welding. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to realize the one-time welding molding of large welds at the stressed parts of the storage tank. 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. Internal welding is an automatic long arm extrusion welding process, which is an important step in all processes. Its principle is the same as external welding, but its equipment is different.

HDPE storage tank is used as a sealed vessel for storing liquid or gas, which is called storage tank. The construction of HDPE storage tank project is an indispensable and vital infrastructure construction for oil and gas, chemical industry, grain, oil and food, food factory, fire safety, transportation, metallurgy industry, national defense safety and other professions. Because the area and environment of use are different, the intensity of sunlight is also different. The intensity of sunlight will have a certain impact on the service life of HDPE storage tanks, so sunscreen is also part of daily maintenance, which can extend the service life and reduce daily wear and tear. In the application process of HDPE storage tank, if conditions permit, it can be placed indoors, which can effectively avoid the problem of sunscreen. However, if the HDPE storage tank is placed outdoors, it must be maintained if it is exposed to wind and rain. Make a sunshade to prevent direct sunlight. The other way is to apply a light color coating on the surface of HDPE storage tank to reduce heat absorption and resist ultraviolet rays, and also improve the aging resistance of HDPE storage tank. In use, factors that can cause certain damage should be avoided, especially the sunscreen problem of polypropylene storage tank.

Physical anti-corrosion of PPH winding tank: during processing, appropriate oily film-forming agent is used in the mesh, so that the anti-corrosion effect of the produced equipment will be much better when it is used. For example, the use of some lead containing pigments and oil together can make the anti-corrosion coating more compact, which will also reduce the penetration of substances to the equipment. Phosphate pigments are basic acid salts that are difficult to dissolve after hydrolysis, which can effectively block the pinholes in the coating. The oxide produced by iron or the flake mica powder and other pigments can reduce the permeability of the anti-corrosion coating when filling, so the PPH winding tank can play a good role in anti-corrosion physically.

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 storage tank has good temperature resistance, acid and alkali resistance, high strength and impact resistance, longer service life, and no environmental stress fracture damage. At present, the tank has become a necessary equipment for chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new materials, new energy, and biomedicine. In the next few years, PPH storage tanks will be widely used. Manufacturing process of PPH storage tank: extruding and winding PPH granular materials. The product is formed at one time without welding. PPH tank is welded by polypropylene plate. In terms of corrosion resistance, PPH vertical storage tank and PH vertical storage tank have similar corrosion resistance. From the perspective of safety performance, the PPH tank shell is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. There is a big gap between the other two properties, such as aging resistance.

PPH storage tank mainly includes core processes such as tank body fabrication, bottom, top, manhole, internal and external welding of inlet and outlet flange interface, which will directly affect the integrity, aging resistance, leakage prevention, service life and mechanical strength of the entire PPH storage tank. PPH storage tank body is manufactured by spiral extrusion winding technology. PPH particles are melted on the spiral extrusion winding machine, and then the molten extrusion materials form a can body on the mold. When the temperature is reduced to a certain extent, the tank can be demoulded to ensure the integrity of the tank. However, in the traditional processing form of polypropylene tank, the plate is welded into the tank. Since the very wide plate is 2000 mm, the height of the tank body is generally more than 2000 mm. In actual processing, the tank bodies are welded one by one and then formed manually. Then, for safety reasons, a stiffening ring is added at the connection of the tank.
