subject: Stainless Steel Pipe Fittings Installation Knowledge [print this page] stainless steel pipe fittings installation method is basically the same with ordinary carbon steel, in some process on the following process requirements.
A stainless steel lifting, not direct contact with other metals, wood or rubber pad should be added non-metallic materials board.
2 pipe cutting wheel does not allow ordinary film with cutting, should adopt special stainless steel cutting wheel tablets or plasma.
Location welding stainless steel pipe fittings should be sufficient when the argon inside weld protection.
4 from the arc and the ending arc, starting with back-arc welding method, revenues arc should be filled crater. From the arc to be completed in the groove, to prohibit the piping and fittings of base metal surface arcing and sparking. If the income from the arc and arc
Discovered holes, cracks and other defects should be clean and timely manner.
5 stainless steel pipes, pipe fittings and stainless steel pipes, fittings and non-stainless steel pipe, tube connections, welded butt joints before backing weld pipe and the cavity should be filled with argon gas protection
Protection is required for TIG welding.
More than 6 from the arc Road Multi-storey Welding, Arc income should be staggered.
7 continuous welded stainless steel, its temperature does not exceed between layers 60 .
8 Department of weld pipe connections welded joint after welding to acid pickling and passivation.
9 stainless steel pipe pressure test on water temperature and water quality have certain requirements, the water temperature of not less than C 5; water chloride content may not be greater than 25Pmm.
