As a widely used equipment in the chemical industry, the excellent performance and characteristics of the Hastelloy reactor are largely attributed to the outstanding properties of its materials. Hastelloy, as a high-performance nickel based alloy, has been favored in many fields due to its high strength, toughness, and corrosion resistance.
Hastelloy reactor is a device used for catalytic reactions, high-temperature thermal reactions, and high-pressure gas-phase reactions. It mainly consists of a kettle body, a stirrer, a heating system, a cooling system, and a control system. It can apply temperature and pressure to the reaction system through the heating or cooling system, while the stirrer ensures uniform mixing of the reaction, thereby achieving chemical reaction or substance conversion.
1、 Characteristics and Applications:
The main material used for the GSHA/type series Hastelloy alloy reactor body is Hastelloy C-276 alloy (Hastelloy C-276 alloy)
A stirring reaction device for chemical reactions of gas liquid, liquid liquid, liquid solid or gas liquid solid three-phase chemical materials, which can fully stir various chemical materials under high pressure, vacuum, and temperature to enhance mass and heat transfer processes.
The main feature of this device is the use of a static sealing structure, with a magnetic coupling connecting the agitator and motor drive. Due to its non-contact torque transmission, static sealing replaces dynamic sealing, which can solve the leakage problem of agitation and keep the entire medium and agitation components in a sealed state for operation. Therefore, it is more suitable for agitation reactions of various flammable, explosive, highly toxic, valuable media and other permeable chemical media. It is a leak free reaction equipment suitable for sulfurization, fluorination, hydrogenation, oxidation and other reactions in petroleum, chemical, organic synthesis, polymer material polymerization, food and other processes.
2、 Material characteristics
The main material of the Hastelloy reactor, Hastelloy, has a series of remarkable material properties.
Firstly, Hastelloy exhibits mechanical properties. Its high strength and toughness enable it to maintain stable operation even under high pressure and high temperature conditions. However, this high-strength characteristic also brings challenges in machining, as it has a strong strain hardening tendency. When the deformation rate reaches a certain level, its hardening effect will be more significant than that of ordinary stainless steel. Therefore, in design and manufacturing, it is necessary to fully consider the material properties, adopt appropriate processes and tools, and ensure the smooth progress of the processing.
Secondly, Hastelloy alloy also has good corrosion resistance. The resistance to pitting corrosion, crevice corrosion, and stress corrosion of this alloy enables it to resist the erosion of various corrosive media. Its high content of Mo and Cr elements endows it with excellent resistance to chloride ion corrosion, while the addition of W element further enhances its corrosion resistance. Therefore, the Hastelloy reactor can operate stably in various harsh chemical environments, greatly improving the service life and reliability of the equipment.
In addition, Hastelloy alloy also has excellent high-temperature oxidation resistance. In high temperature environments, it can resist the effects of oxidation and thermal stress, maintaining its stable performance. This makes the Hastelloy reactor perform well in chemical reactions that require high-temperature operation, and can meet the needs of various complex processes.
