The anti-corrosion means of PPH storage tank are cathodic protection and coating protection. Coating protection can be divided into two ways, namely, internal anti-corrosion treatment and external anti-corrosion treatment of PPH storage tank. For oil storage or product oil storage tanks, the required performance of anti-corrosion coating in the tank is electrostatic conduction. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is to combine the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH tank, the temperature resistance characteristics between anti-corrosion coatings must be considered, which is interchangeable. In the alkyd anti-corrosion coating, direct combination use must be avoided. This is because of chemical reaction with zinc powder. Cathodic corrosion protection of storage tank includes impressed current cathodic protection of storage tank bottom plate and protection treatment of storage tank ponding layer anode. Cathodic corrosion protection of storage tank is divided into impressed current cathodic protection on the outside of the bottom plate of the storage tank, and protective treatment on the anode of the ponding layer in the tank.

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.

The main purpose of the mixing tank is to mix, mix, blend and homogenize materials. Features: Convenient, convenient, time-saving, effectively shortens the mixing time, saves labor, and speeds up production. It is the main equipment for modern industrial production. PPH mixing tank uses PPH spiral extrusion winding unit to process PPH granules into tank body molding process. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. PPH mixing tank is characterized by good integrity, uniform thickness, corrosion resistance, seam free, aging resistance and good leakage resistance. This product is widely used in chemical industry, metallurgy, rare earth, electronics, dyes, pigments, dyes, environmental protection, pharmaceuticals, power plants, brewing and other industries.

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 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 the process of using PPH spiral extrusion winding unit to process PPH granules into can body molding. 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.

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.
