The construction of thin-walled stainless steel pipes should comply with relevant national standards such as 10S407-2 "Installation of thin-walled stainless steel pipes for building water supply".

1、 Construction steps

1Before welding: The ends of pipes and fittings must not have traces of grease, paint, ink lead, sand particles, or dirt sticking;

2Piping: Use a pipe cutter or grinding wheel cutting machine (the cutting blade should be dedicated) to vertically cut the steel pipe, and clean the end burrs and round them;

3Assembly: When inserting the stainless steel pipe into the socket of the pipe fitting, press against the bottom of the socket;

4Welding: Tungsten argon arc welding (abbreviated as TIG welding)TIG welding), weld the socket end in a circular shape, with a smooth and fully fused weld seam, without defects such as pores, cracks, or weld penetration;

5. Weld treatment: Use mechanical polishing or use a special cleaning agent to remove the weld reflow color.

2、 Welding process characteristics

1Tungsten argon arc welding has the characteristics of low heat input and excellent welding quality, making it particularly suitable for welding thin plates and thin-walled pipe fittings;

2The socket welding connection method is simple in welding, and there is no need to add welding wires during welding, which not only saves welding consumables, improves welding speed, but also ensures thatThe high-quality TIG welding of thin-walled parts avoids the complexity of using electrode arc welding;

3. Tungsten argon arc welding does not produce flames or splashes when welding stainless steel materials.
