Pipes, pipe couplings, valves and access on the device takes over the join method, by the nature of the fluid, pressure and temperature as well as the pipe material, size and installation location and other factors, mainly thread connection, flange connection, socket connections and welded 4 different methods:
① threaded connection: mainly suitable for small diameter pipe. When you join, generally to fluoroplastic seals on the screw connection parts around or coated with thick paint, round sealing materials such as hemp thread to prevent leakage. More than 1.6 MPa pressure, usually do many Beveling and gasket seal. This connection method is simple, and can be removed to reinstall, Union subject to the proper space in the pipeline to facilitate disassembly.
② flange connection: for larger diameter range. Join, according to the nature of the fluid, pressure and temperature with different flange and gasket, bolt clamping the gasket seal. In need of frequent disassembly of pipe and tube is connected with the equipment used in flange joint.
③ socket connection: for cast iron pipe, concrete pipes, vitrified clay pipe and joints between pieces join, only applies to low-voltage ambient temperature conditions of water supply, drainage and gas pipelines. Join, fill in the grooves of the socket into silk, cotton, or asbestos rope, then use materials such as asbestos-cement or lead filled, can also fill rubber sealing ring in the socket so that it has good flexibility, allowed to tubes with a small amount of movement.
④ welded joints: the strength and tightness of the connection the best, suitable for various piping, saving labor and materials, but removal should be shut off, pipes and pipe couplings.
