Method for welding stainless steel pipe fittings common thread

　　Method for welding stainless steel pipe fittings common thread:

　　Stainless steel threaded pipe fittings stainless steel tube is inserted tube bearing part of the mouth and then along the edge of the fitting a circle of argon arc welding pipe fittings is all connected in the most reliable connection. The diameter of pipe fittings is equal to the outer diameter of the pipe. The stainless steel screw thread pipe fittings manufacturers tell you.

　　1, butt welding type

　　Butt welded stainless steel screw thread pipe fittings is the stainless steel tube and pipe fittings counterparts along the seam do a circle of argon arc welding pipe fittings, and welding. The diameter of pipe fittings is equal to the outer diameter of the pipe. Butt welding is generally used for the specification of large stainless steel piping systems.

　　2, press fitting

　　Clamping pipe fittings with safe and reliable connection, construction is convenient, suitable for embedded installation, free maintenance update, economy relatively superior characteristics. Card the working principle of pressure pipe is thin wall stainless steel pipe is inserted into a card type pipe fittings socket, using special card pressing tools will be stainless steel pipe die in the tube, the entrapment section shape is hexagonal, coupled with stainless steel tubes and fittings between have O-ring seal the with check leakage, anti pull, anti vibration and high pressure etc. characteristics.

　　The correct method, 3 stainless steel pipe welding thread:

　　] the correct selection of welding materials and use with low carbon and water stabilizing elements of welding material, containing a moderate amount of iron ferrite promote elements (Cr, Mo, Si, etc.) of welding consumables and restricted.

　　The impurity content in the weld

　　The rear gas protection

　　The cleaning using austenitic stainless steel wire brush

　　The processing facilities, materials and tools to clean up and stored separately with other materials

　　A color processing and pickling after welding

　　] but this is the welding process of austenitic stainless steel, if iron ferrite, martensite or double phase so much the same can be said for, the election to electrode.
