When the storage tank made of polyethylene is produced and processed again, it does not need to use traditional welding, so its volume will be larger when it carries liquid. Because the HDPE storage tank does not need to be welded, so there is no weld. When it is used again, it does not need to worry about instability due to too much carrying liquid. Generally speaking, most storage tanks have a stability coefficient. The reason why the stability performance of storage tanks is different is that the performance of raw materials used is different. If the materials used are poor, even if the process is good, the stability performance is not guaranteed. When selecting raw materials for storage tanks, the first thing we should do is to check the quality certificate and inspection report of the raw materials. After checking, all data can be put into production only if they meet the standards. Besides, plates are used at the top and bottom of the tank, so there are requirements for plates.

PPH storage tank has the advantages of corrosion resistance, corrosion prevention, long service life, light self weight, high strength, safe transportation, convenient maintenance, etc. The working pressure of PPH storage tank is normal pressure, and the working temperature is PPH-10 ℃~120 ℃, and PVC-40 ℃~60 ℃. PPH storage tank has the advantages of one-step forming without welding joint, impact resistance, aging resistance, light weight, no leakage, acid and alkali resistance, long service life, and compliance with health standards. PPH storage tank has excellent chemical corrosion resistance, and has good corrosion resistance to inorganic acid, alkali and salt (except oxidizing media). Common PPH tank solutions include dilute sulfuric acid, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, phosphoric acid, ammonia, etc. Rotational plastic anti-corrosion PP storage tank has great advantages in large size, large capacity and large volume products. Although the volume is large, it only maintains the characteristics of one-time molding integrity, which is beyond the reach of other storage tank processes. Compared with the traditional anti-corrosion storage tank, the price is low and the performance price ratio is high.

The small softening point of PPH storage tank is 108 ℃, and the large fragmentation point is - 70 ℃, so PP storage tank can generally be used to hold liquid with temperature ranging from - 40 ℃ to 60 ℃. The feed inlet, discharge outlet, liquid level gauge outlet, flange, etc. on the PPH storage tank body are all integrally formed and welded at one time, without additional feed inlet and outlet. When containing acid-base substances, acid-base resistant gaskets shall be provided. When organic substances (especially organic solvents) are contained, insoluble rubber gaskets shall be provided. PPH storage tank is made of polypropylene, which can contain inorganic acids, malic acid, salts, ammonium, alkalis, oils and most gaseous organic substances at normal temperature and pressure. PPH storage tank cannot be used to contain strong oxidants, such as concentrated sulfuric acid, concentrated nitric acid, etc. When using PPH storage tank, we should not forget that it is just a tool we use. If the tool is not used properly, it will also break down. Therefore, why we use PPH storage tank with different life depends on how we treat them.

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.

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 ℃.

PPH waste gas purification tower is also called PPH waste gas treatment tower. In industrial production, with the chemical processes such as pickling and electroplating, different concentrations of acid and alkali containing gases are generated, causing serious environmental pollution. PPH waste gas treatment tower is an ideal equipment for purifying gas containing acid and alkali. It was successfully developed after digestion, transplantation, test and continuous improvement of imported equipment. Function: Mainly used for environmental protection equipment for acid/alkali waste gas treatment such as sulfuric acid, nitric acid, hydrofluoric acid and hydrochloric acid during operation. The acid mist purification tower has high purification efficiency, compact structure, small floor area, good corrosion resistance, aging resistance, light weight, easy installation, transportation, maintenance and management, etc.
