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 ℃.

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.

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.

For the treatment of corrosive gases (such as acid and alkaline waste gas) in PPH waste gas tower, liquid absorption method is often used. The key to control the waste gas by liquid absorption is the selection of purification equipment. The main development is acid and alkaline waste gas purification process and equipment with high purification efficiency, simple operation and management, and long service life. This process and product are characterized by simple structure, low energy consumption, high purification efficiency and wide application range, and can effectively remove water-soluble gases such as hydrogen chloride (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), cyanuric acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), formalin (HCHO), etc. The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and sodium hydride absorption liquid are fully contacted, absorbed and neutralized by gas-liquid two-phase reaction. After purification, the acid mist waste gas is dewatered and defogged by the demister, and then discharged into the atmosphere by the fan. The absorption liquid is sprayed down from the tower top after being pressurized by the water pump at the tower bottom, and then flows back to the tower bottom for recycling.

PPH storage tank vertical storage tank is a plastic storage tank made of PPH granular materials after processing. The barrel of PPH storage tank is made of PPH granules through extrusion and winding process, and the product is formed at one time without welding. PPH storage tank is made of polypropylene plate by welding. From the perspective of corrosion resistance, the corrosion resistance of PPH vertical storage tank is similar to that of PPH vertical storage tank. From the perspective of safety performance, the PPH tank cylinder is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. And there is a big gap between the other properties of the two, such as anti-aging performance. The nozzle installation is the last process, which is equivalent to the reduced version of bottom welding. That is, the imported small automatic extrusion welding unit is used to weld the connecting pipe and flange into shape, and then the hole opener is used to cut the corresponding caliber on the tank body, and then the domestic portable extrusion welding is used. PPH storage tanks are widely used in chemical, pharmaceutical, dye, chemical fiber, metallurgy, textile and other industries to store various corrosive media. The utility model has the advantages of long service life of corrosion resistance, light self weight, safe transportation, convenient maintenance, etc.
