Steel sealed containers for storing liquids or gases is the steel tanks, steel tanks are petroleum, chemicals, grain, food, fire, transportation, metallurgy, defense and other industries essential, vital infrastructure. Category: Because of different storage media, in the form of the tank is varied. By location Category: can be divided into ground storage tanks, underground tanks, semi-underground storage tanks, marine tanks, storage tanks and other seabed. By oil Category: can be divided into crude oil tanks, fuel tanks, lubricating oil tank, oil tank, fire water tanks and so on. By Application: can be divided into the production of tanks, storage tanks, etc. In the form classification: can be divided into vertical tank, horizontal storage tanks. Classification by structure: can be divided into fixed roof tanks, floating roof tanks, spherical storage tanks. Classification by size: 100m3 over large tanks, mostly vertical tank; 100m 3 or less for small tanks, mostly horizontal tank. Material tank: mainly Q345R, S30408 ??(304), S31603 (316L), S32168 (321), and in accordance with the requirements of the different media production of titanium (TA2), nickel material, zirconium, Hastelloy, reactor within Spray PTFE, lined nickel (Ni6) and composite panels. Qingfeng Weihai Chemical Machinery Co., Ltd. (formerly: Weihai Ruifeng Chemical Machinery Factory) is specialized in magnetic and magnetic stirrer reactor manufacturers, strong technical force. Processing equipment testing means perfect. Production reactor and magnetic stirrer using advanced static seal magnetic coupling device, completely solve the mechanical seals and packing seal leakage can not solve the problem. Able to meet the requirements of high temperature, high pressure, hydrogenation, flammable, dry, poisonous occasions. Plant products after ten years of unremitting efforts, the product has been standardized, serialized, but also can produce all kinds of feed tanks, condensers, heat exchangers and various resins devices. In addition, according to the user's requirements, special design and manufacturing. I plant products safe, reliable, easy to use, sold throughout the country, the majority of users trust and support.
