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.

What are the anti-corrosion treatment of PPH storage tank? For PPH storage tanks storing oil and product oil, since the performance required by the anti-corrosion materials in PPH storage tanks is electrostatic conduction, all PPH storage tanks shall be subject to anti-corrosion treatment with electrostatic conduction coating. The treatment of the external anti-corrosion coating of the tank is a comprehensive treatment that takes into account the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH storage tank, it is necessary to consider that each anti-corrosion coating has temperature resistance and compatibility. If the alkyd anti-corrosion coating is used, it is necessary to avoid direct matching, because it will react with zinc powder. The cathodic corrosion protection of the tank is divided into impressed current cathodic protection on the outside of the bottom plate of the tank, and protective treatment on the anode of the ponding layer in the tank.

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.

The forming process of PPH storage tank adopts spiral extrusion winding technology with reliable quality. The main processes include tank extrusion winding, external welding, internal seam welding, pipe orifice installation, etc. Can body extrusion winding is a process that uses PPH spiral extrusion winding unit to process PPH granules into a can body. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency of this process is about 5-8 times higher than that of manual process, and the product is flat and beautiful, with good integrity, no joints, good corrosion resistance and leakage resistance. The tank body is thin at the top and thick at the bottom, and the size and shape of the product are not limited. External welding is the process of using the imported automatic extrusion welding unit to make the large weld of the tank with large stress be welded in one time. 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. The process features high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld, reduce flash, and make the joint smooth and beautiful. In addition, the ultraviolet absorber is added to PPH granular material to resist aging and extend the service life.

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.
