The connection method of the overall jacket and the cylinder

glass lined reactor,There are two types of connection between the integral jacket and the cylinder, detachable and non-detachable. The non-removable jacket has a simple structure and reliable sealing. "Carbon steel" jacket can be directly combined with "carbon steel" (carbon steel is the most common type of material in steel, mainly composed of iron and a small amount of carbon, the full name of carbon structural steel, commonly used in general engineering structures) The kettle body is welded; the connection structure between the two when the kettle body is equipped with a carbon steel jacket is made of "stainless steel" (steel that can resist the corrosion of the atmosphere and general acid, alkali, and salt), which is characterized by avoiding the direct contact between the stainless steel kettle body and the carbon steel. Steel parts are welded to prevent the loss of alloying elements in stainless steel during welding. If the kettle body and the jacket are made of different materials, and the two materials are not suitable for welding connection, or if the reaction operating conditions are bad and require regular inspection of the kettle body surface, a detachable connection should be used. The medium pressure in the overall jacket generally cannot exceed 1MPa. Otherwise, the wall thickness of the kettle body is too large, which increases the difficulty of manufacturing. When the medium pressure in the jacket is large, the welded semi-circular pipe jacket and "section steel" (referring to the steel rolled by the rolling mill and sold in the market with a fixed cross-section, such as angle steel, round steel, flat steel, etc.) The jacket and the honeycomb jacket can not only increase the flow rate of the heat transfer medium, improve the heat transfer effect, but also improve the ability of the cylinder to withstand external pressure, but the welding workload of the above structure is too large, which brings great trouble to the manufacturing.
