Stainless steel pipe fitting materials can't contact with other metals directly when lifting, non-metallic materials such as wood or rubber sheet should be padded.

Arc striking and arc stopping of stainless steel pipe fittings: back welding method should be adopted for arc striking and must be made within the groove, arc stopping should fill arc crater. Arc striking should be avoided in the pipeline and on the surface of pipe parent metal. If defects such as holes and crack are found when arc starting and arc stopping, they should be cleaned up.

Arc striking and arc stopping of stainless steel pipe fittings of multi-channel multi-layer welding should be staggered.
Argon tungsten-arc welding can be carried out only if the inner of pipes and cavity are protected by filling argon gas before back welding of stainless steel pipe fittings, pipe fittings and stainless steel pipes, pipe fittings and stainless steel pipes, pipe fittings connection and butt joint.

When stainless steel pipe materials are welded continuously, the interlayer temperature should be less than 60 degrees Celsius.

Inner side of the welding should be filled with argon to be protected when tack weld stainless steel pipe fittings, pipes and fittings.

Cutting of stainless steel pipe fittings and pipes is not allowed to adopt common grinding wheel to cut, instead, special grinding wheel or plasma cutting only for stainless steel pipe fittings should be adopted.

Weld joint of stainless steel pipe fittings must be carried out acid pickling and passivation treatment after welding.

Hydraulic test of stainless steel pipes has certain requirements on water temperature and water quality: the water temperature shall not be less than 5 degrees Celsius; the content of chlorine ion in the water shall not be greater than 25 Pmm.
