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.

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.

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. In the actual engineering construction and application, the vertical PPH storage tank usually only considers the static load due to the low application frequency, and the safety performance is slightly increased. For the vertical PPH storage tank with large capacity, the concrete rubber support and the metal rubber support can be considered, but the metal rubber support is too tightly bound, and the plastic has some folding and swelling, It will do harm to the compressive strength of the storage tank, and the appearance is not beautiful. It is proposed to use concrete rubber bearings. Second, for those with small capacity, it is OK to immediately consider plastic rubber bearings.

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.
