How to choose the material of the reactor and the mixer? Due to different production processes and operating conditions, the reaction kettle is divided into electric heating, steam heating, and thermal oil circulation heating. The shaft sealing device is divided into packing sealing, mechanical sealing, and magnetic sealing. The mixing types include anchor type, slurry type, turbine type, propulsion type, self suction type, and frame type.

Conventional materials for autoclave include: 06Cr18Ni10 (304), 06Cr18Ni11Ti (321), 022Cr17Ni12Mo2 (316L), Q245R, Q345R, 15CrMoR explosive composite plates, etc.

Special materials for autoclave include: 00Cr20Ni25Mo4.5Gu (904L), 2205 dual phase steel, nickel (N6), titanium (TA2), zirconium series, Monel, Hastelloy B/C, tantalum, tetrafluoro lining and other composite plates.

TA2 composite plate reactor (titanium steel composite plate reactor) Industrial pure titanium is divided into three grades based on its impurity content: TA1, TA2, and TA3. The interstitial impurity elements of these three industrial pure titanium gradually increase, so their mechanical strength and hardness also gradually increase, but their plasticity and toughness correspondingly decrease. The commonly used industrial pure titanium in industry is TA2, due to its moderate corrosion resistance and comprehensive mechanical properties. TA3 can be used when there are high requirements for wear resistance and strength. TA1 pure nickel is a silver white metal when good molding performance is required. Due to its excellent corrosion resistance, high electric vacuum performance and electromagnetic control performance, it is widely used in chemical industry, mechanical electronics, food and other aspects. Pure nickel has excellent welding and processing properties.

Nickel and nickel alloys can be processed into tube, rod, wire, plate, and foil products. N6 is the most widely used material in industry, with excellent mechanical properties and excellent corrosion resistance in many corrosive environments, especially in caustic soda corrosion.

Hc276 high-pressure reactor, Hc276 has the following characteristics:

1. It has excellent corrosion resistance to most corrosive media in both oxidation and reduction states.

2. Excellent resistance to spot corrosion, crevice corrosion and stress corrosion cracking. The application field of Hc276 has been widely applied in the chemical and petrochemical fields, such as in components and catalytic systems that come into contact with chloride containing organic compounds. This material is particularly suitable for use in high-temperature, mixed inorganic and organic acids (such as formic acid and acetic acid), and seawater corrosive environments. Hc276 high-pressure reactor, in which Hc276 material is used in other application fields:

3. Pulp and paper industry, such as digester and bleach containers

4. Washing tower, reheater, wet steam fan, etc. in FGD system

5. Equipment and components operating in acidic gas environments

6. Reactors for acetic acid and acidic products

7. Sulfuric acid condenser

8, Methylene diphenyl isocyanate (MDI)

9. Production and processing of impure phosphoric acid
