There are many connection methods of stainless steel pipe, but there are more commonly used or compression type, pressing type, live connection type, propulsion type, push thread type, bearing welding type, live connection type flange connection, welding type and welding and traditional connection of the derived series of connection mode and so on. These connection methods are simple to operate, firm and reliable.
(1) Threaded connection pipe fittings threaded connection pipe fittings are galvanized and non-galvanized, which are generally made of malleable cast iron. There are pipe joints for the connection of two pipes and other pipes; different diameter pipe (size head) for connecting two pipes with different diameter; equal diameter and different diameter for the connection of two pipes in vertical crossing; live joints for pipes that need to be removed frequently.
(2) Flange, bolt and gasket flange connection includes three parts: upper and lower flange, gasket and bolt nut. Flat welding flange is suitable for the nominal pressure not exceeding 2.5MPa. Its strength, not easy to deformation, sealing performance is good. Rubber asbestos mat is the largest amount of flange joint pad, can be applied to many media, such as steam, gas, air, brine, acid and alkali. It is widely used in petrochemical process pipelines. The tooth pad is made of ordinary carbon steel, low alloy steel and stainless steel.
