Neijiang PPH storage tank manufacturing
The key manufacturing method used in the production of PPH storage tank is one-time forming coiling manufacturing method, so it is simple in structure. The application of PPH storage tank is relatively convenient due to its simple construction. When the rubber bearing is a plastic rubber bearing, the compressive strength, stiffness, service life and total number of manufacturing shall be considered. When the rubber bearing is a metal rubber bearing, the other standards shall be the same as 1. In addition, the surface of metal rubber bearing shall be corrosion resistant. When the rubber bearing is a concrete rubber bearing, the concrete rubber bearing of the first horizontal tank shall consider the compression strength provisions, and the total number of rubber bearings shall be 2. When there are several rubber bearings, their design elevation shall be the same, and there is no need for uneven ground settlement, and the bottom shall be basically flat.

Pph storage tank is a kind of plastic container made by rotational molding process. it has become the equipment needed for chemical industry, smelting, mining and new materials. Do you know what problems should be paid attention to during the installation and use of pph storage tank? The platform for installing pph storage tank shall be able to bear the weight of storage tank and solution. The platform shall be flat and smooth to prevent some sharp objects from damaging the storage tank. If heavy additional equipment is installed on the tank, or if a person needs to work on the top of the tank but the tank cannot bear the weight of a person, support or related equipment should be used to assist in the operation. When the liquid inlet is higher than the tank bottom, the liquid inlet shall bend towards the tank wall to let the incoming liquid flow along the tank wall, so as to reduce the direct impact of liquid on the tank bottom. When storing chemical liquids, first communicate with the manufacturer to determine the specifications of storage tanks, such as thickened storage tanks. In use, if pph storage tank needs to be monitored, it can be monitored by level gauge or induction device. When it has been used for a long time, please refer to the storage requirements of pph storage tank and clean the residual liquid in the tank in time. If a large amount of liquid is sucked in and discharged from the pph storage tank, special technicians need to be arranged to install the corresponding exhaust pipe.

The key requirements of PPH tank design are: no danger, reliable: the data of high strength and toughness of materials, and the interchangeability structure of media should have sufficient rigidity and pressure bending performance, and the sealing performance should be good. Meet process request: function request of life request. Good comprehensive economy has high consumption efficiency, low consumption coefficient, reasonable structure, complicated manufacturing, convenient transportation and convenient equipment. Easy to operate, maintain and control: maintain and better control. Good environmental performance of PPH storage tank: At present, great progress has been made in the design scheme, engineering construction and data information of large and medium-sized storage tanks in China. However, our country still lacks experience in the design and construction of high strength data of large storage tanks. In the future, our country should strengthen the development and implementation of large storage tanks to make the production process of large storage tanks more carbon friendly.

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.
