Installation of stainless steel pipe

The installation method of stainless steel pipe is basically the same as plain carbon steel, and it has the following technological requirements in some process.

1. The hoisting of stainless steel pipe shall not be in direct contact with other metals, and shall be added with planks or rubber plates and other non-metallic materials.

2 pipe cutting shall not be cut with ordinary grinding wheel. It shall be made of stainless steel special grinding wheel or plasma cutting.

3 stainless steel pipe and fittings shall be protected by argon during position welding.

The arc must be filled in the arc crater. The arc must be finished within the groove, and the arc and arc of the pipe and the pipe are forbidden. If the arc and arc are found, the holes and cracks should be cleaned in time.

5 stainless steel pipe, pipe fittings and stainless steel pipes, pipe fittings and stainless steel pipes, pipe fittings connection, before backing welding butt joint welding pipe and cavity should be filled with argon gas protection, to tungsten argon arc welding.

The arc and arc of the six multi - channel welding shall be staggered.

7 continuous welding stainless steel material, its interlayer temperature less than 60 ℃.

The welded seam of the stainless steel pipe shall be treated with acid and passivation after welding.

The water pressure test of stainless steel pipe has certain requirements for water temperature and water quality. The chloride content in water should not be greater than 25Pmm.
