Stainless steel pipe fittings are the collective name of various stainless steel pipe connection workpieces. They have the characteristics of easy installation, high performance and durability, and are widely used in various pipeline construction and installation. So, how to install stainless steel pipe fittings? Let's take a look with the editor.
1. The arc starting of stainless steel pipes adopts the re-welding method, and the arc closing adopts the method of full arc crater. The arc starting should be completed in the slope, not on the surface of the pipe and pipe fitting busbar. In the process of arc starting, cracks, pores, etc. are found, and they must be cleaned up in time.
2. The stainless steel pipe fittings should be separated from other metals when they are hoisted to avoid direct contact. Can be used to padded wood, rubber and other non-metallic materials isolation method.
3. The temperature of stainless steel pipe fittings cannot exceed 60 degrees Celsius during continuous welding. When tack welding, the inside of the weld should be filled with argon for protection. When cutting, you cannot use ordinary grinding wheels to cut, you should use special grinding wheels for stainless steel pipes or plasma cutting. Sharing from Cangzhou Aerospace Pipeline.
4. When connecting stainless steel pipe fittings and non-stainless steel pipes and fittings, the inner and cavity of the pipes and cavities should be filled with argon before the butt joints are welded, and then TIG welding can be carried out. The welding seam at the connecting welding port should be pickled and passivated after welding.
