The autoclave is a horizontal cylindrical device made of steel. The autoclave is a horizontal and cylindrical device made of steel. The shell and lid are welded with 16MnR steel plates. The neck and lid flanges are integrally forged with 16Mn. The welds are subject to strict X-ray inspection according to specifications. Movable quick opening kettle doors are set at both ends, and door opening safety interlock device is set. The kettle door is sealed well with nitrile rubber double sealing ring. A movable support is arranged under the kettle body to adapt to the thermal expansion and cold contraction of the kettle body.

Autoclave It is a large pressure vessel for steam curing of aerated concrete blocks, lime sand bricks and coal ash bricks, and the hot water reaction of CaO+SiO2+H2O is completed in the kettle. At the same time, it is also widely used in production projects requiring pressure steam curing production process, such as high-strength gypsum, thermal insulation materials, rubber products, high-strength glass, cement pipe piles, wood, medicine, chemical and other industries.

Autoclaves belong to special equipment and pressure vessels, so once an accident occurs, it will bring serious consequences. We need to know what the hidden security risks are, and avoid and prevent them.

1. Overload: pressure vessels such as autoclaves are vulnerable to sudden changes in chemical reaction and instrument failure, resulting in overload. Once the equipment is overloaded, if the safety device fails or fails, it may quickly cause an accident.

2. Complex service conditions: the working conditions of pressure vessels are variable (from high temperature to deep cold), and the pressure is also variable. Therefore, any minor defects left in the manufacturing process may expand rapidly under appropriate conditions, resulting in accidents. Therefore, enterprises need to purchase pressure vessel products with reliable quality.

3. Complex stress conditions: pressure vessels such as autoclaves are generally simple in structure, but their stress conditions are complex, including both primary stress and secondary stress, as well as peak, temperature stress and residual stress. Especially, stress concentration is easy to occur at openings and geometric mutations. In addition, they are also subject to cyclic stress, resulting in low cycle fatigue.

4. Corrosion: due to the corrosion of the working medium during the production process, the vessel wall becomes thinner and the material deforms, and the pressure accelerates this corrosion, such as intergranular corrosion and stress corrosion of pressure vessels.

For these situations, we need to Autoclave The operators should do a good job of pre job training, be familiar with the reaction of autoclaves in various situations, and deal with it in a timely manner. Establish and improve the use and maintenance rules of autoclaves, and clarify the responsibility system. Maintain the autoclave regularly.
