Stainless steel threaded pipe fittings are the collective name for various stainless steel pipe connection workpieces. They have the characteristics of easy installation, high performance, and durability. They are widely used in various pipeline construction and installation. So, how to install stainless steel threaded pipe fittings? Let's take a look with the editor.
1. The arc starting of stainless steel threaded pipe fittings 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, and the arcing and starting of the arc on the surface of the pipe and the pipe fitting bus bar should not be completed. In the process of arc starting, cracks, pores, etc. are found, and they must be cleaned up in time.
2. When the stainless steel threaded pipe fittings are hoisted, they should be separated from other metals to avoid direct contact. Can be used to padded wood, rubber and other non-metallic materials to isolate the method.
3. The temperature of stainless steel threaded 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 can't use ordinary grinding wheel to cut, you should use Cangzhou stainless steel threaded pipe special grinding wheel or plasma cutting. Sharing from Cangzhou Aerospace Pipeline.
4. When connecting stainless steel threaded pipe fittings and non-stainless steel pipes and fittings, the inner and cavity of the welded butt joints should be filled with argon before the bottom welding, and then argon tungsten arc welding can be carried out. The welding seam at the connecting welding port should be pickled and passivated after welding.
