Information

      Special equipment for reducing three-way pipe fittings: Install an ejector device on the pipeline, which includes metal rods, pushers, commutators, brackets, etc.; when the metal rods are heated, jacks and metal rods are used to push out, The pipe wall materials are naturally turned out to form a reducing tee blank; then a pipe section of a certain length corresponding to the standard is welded on the reducing tee blank formed by the ejector to produce the final product. Make a symbol on the pipe where the reducing tee is to be processed, and punch through the symbol.

      Ordinary rubber gaskets are suitable for occasions where the temperature is lower than 120°C; asbestos rubber gaskets are suitable for occasions where the temperature of water vapor is lower than 450°C, the temperature of oil is lower than 350°C, and the pressure is lower than 5MPa. Regarding general corrosiveness The most commonly used medium is acid-resistant asbestos board. In high-pressure equipment and pipelines, metal gaskets of lens type or other shapes made of copper, aluminum, No. 10 steel, and stainless steel are used. Most of the gaskets are cut from non-metallic plates, or manufactured by professional factories according to regular standards. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc.; thin metal plates (white iron, stainless steel) are also used to remove asbestos A metal-clad gasket made of non-metallic materials.

      The processing method of reducing tee fittings is suitable for the processing of reducing tee fittings on pipes of different standards; its special processing equipment has simple structure and low cost. The manufacture of reducing tee fittings does not require other injection molding machines and injection molds. The production cost of such pipe fittings can be reduced, and the production power can be improved. The parts that connect the pipe and the pipe to each other are connected to the pipe end.

      There is also a wrap-around gasket made of thin steel tape and asbestos tape. The touch width between the high-pressure gasket and the sealing surface is very narrow (line touch), and the processing finish of the sealing surface and the gasket is relatively high. There are three types of flange sealing surface: flat sealing surface, suitable for occasions with low pressure and non-toxic media; concave-convex sealing surface, suitable for occasions with slightly higher pressure; tongue and groove sealing surface, suitable for flammable and explosive , Toxic media and high pressure occasions. A gasket is a circular ring made of materials that can undergo plastic deformation and have a certain strength.
