PPH storage tank is also a polypropylene storage tank. Polypropylene can be divided into many types, and PPH is only one of them. PPH storage tank has great advantages in strength, acid and alkali resistance, aging resistance and appearance. The plastic storage tank is made of polypropylene (PP), reinforced polypropylene (PPH) and other raw materials, and is integrally molded by a special rotational molding process. There are no welding, no leakage, light weight, aging resistance, impact resistance, corrosion resistance, and long service life. So there is only one letter difference between PPH storage tank and PP storage tank. Is there any relationship between them? Don't tell me, there are really connections and differences. Let's get to know. PPH storage tank is formed by using alloy polypropylene technology at one time, but PP storage tank is rolled with polypropylene sheet, so its anti-corrosion performance will be much lower. PPH storage tank is more resistant to temperature than ordinary polypropylene, and can resist the erosion of strong chemicals. In addition, the properties of PP material and PPH material are similar, acid and alkali resistant and corrosion resistant. PPH storage tank is more expensive than PP storage tank. The plastic storage tank has great performance in terms of performance and is relatively durable. To some extent, it is a kind of tank that cannot be replaced by ordinary storage tanks.

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 performance characteristics of PPH storage tank are anti-corrosion and free of leakage. Easy to install, maintain and replace. Long service life, good sealing performance. High polymer plastic sliding roller can prevent the strip steel surface from being pulled during pickling. PPH storage tanks are commonly used for the storage and temporary storage of production materials in chemical, petroleum, medicine, food, grease, printing and dyeing, metallurgy, environmental protection, light industry and other industries. Because PPH storage tank has unique advantages over traditional anti-corrosion tank. Next, the advantages of PPH storage tank are introduced in detail. PPH storage tank has good integrity, no welding, no leakage, impact resistance, high tensile strength, good aging resistance, and meets the hygienic food standards. Due to the good performance of LLDPE and the special structure of polypropylene rolling tank, the service life of LLDPE can reach more than 15 years. Good chemical resistance. Except for some solutions that can make it expand, it can bear most of the material solutions. Polypropylene tank has the characteristics of internal and external anti-corrosion, and can be placed in a highly corrosive environment. Generally, the working conditions of storage tanks are atmospheric temperature and pressure; Under special circumstances, the working conditions of the storage tank can be lower than 70 ℃, and the hydraulic pressure can be less than 1 kg/cm2.

Safety method for HDPE storage tank operation: When entering the construction site, workers shall wear safety helmets and fasten safety belts for high-altitude operation. Foam fire extinguishers and other fire-fighting equipment shall be placed separately on site. In case of any abnormal phenomenon during the pressure test of HDPE storage tank, it is strictly prohibited to operate under pressure. If there is abnormal movement of rh during commissioning, it shall be parked for inspection. When installing HDPE storage tanks, special personnel shall be assigned to command the lifting and commissioning, and multiple command is prohibited. When lifting HDPE storage tanks, irrelevant personnel are not allowed to enter the site. When lifting heavy objects, the rh person shall not stand below, and the construction site shall be provided with a protective fence. Construction power needs to be connected by special electricians, and non special electricians are not allowed to connect. The construction site is an extension of the factory area. It is forbidden to hit other equipment and process pipes during construction. The original pipes or equipment shall be drilled and approved before construction. HDPE tanks are widely used because of their superior performance. While focusing on personal safety, everyone can increase efficiency and product value through safety measures. The above is about the safety method of HDPE storage tank operation. You can understand that good results can be achieved only by following the correct operation method in the use process.

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.
