When we use the stainless steel pipe fittings, in many cases, the need for the installation of a special process, such as need some welding, etc., according to different requirements, the possible connection methods are also different, so that more conducive to the use of stainless steel pipe fittings, the following yaang common connection methods according to share information about stainless steel pipe fittings.
1, stainless steel pipe fittings used ignition welding, arc extinguishing the full arc pit method. In striking had said should be made within the slope, not in the pipes and pipe fittings since arc and arc generatrix surface. In the process of striking find the phenomenon such as crack, air hole, clean to handle in time.
2, stainless steel pipe fittings at the time of lifting, should be separated with other metals, avoid direct contact. You can use the non-metallic materials such as padded board, rubber isolation method.
3, stainless steel pipe fittings in continuous welding, the temperature is not more than 60 degrees Celsius. Tack welding, weld the inside should be filled argon protection. Did not use common grinding wheel cutting cutting, should use the special grinding wheel piece of stainless steel pipe fittings or plasma cutting.
4, stainless steel pipe fittings and stainless steel pipes, pipe fittings of connection, welding butt joint of backing welding and before the pipe cavity should be filled with argon, can only be carried out after the tungsten electrode argon arc welding. In the connection of weld joint, after welding for pickling and passivation.
