Stainless steel pipe installation techniques are the following nine considerations:

1, FD-LOK stainless steel tube weld fittings, not in direct contact with other metals, wood or rubber should be padded panels and other non-metallic materials.
2, pipe cutting allowed to use ordinary grinding wheel cutting, should be made of stainless steel special grinding wheel or plasma cutting.
3, the inner side of the weld should be filled with argon protection stainless steel pipe and tube tack welding.
4, arc and ending arc, arc welding method using back, crater should be filled crater. Arcing must be completed within the groove, is prohibited in pipes, fittings base metal surface arcing and arcing. If the arcing found at the crater holes, cracks and other defects should be promptly dealt clean.
5, stainless steel pipes, pipe fittings and FD-LOK stainless steel fittings, pipe fittings to connect with non-stainless steel pipes, pipe fittings, welded butt joint backing tube and the cavity should be filled with argon, in order to carry out TIG welding before.
6, multi-channel multi-arc welding, the arc of the income should be staggered.
7, stainless steel continuous welding, interlayer temperature does not exceed 60 ℃.
8, pipeline welds at weld after welding to pickling and passivation.
9, FD-LOK Stainless steel pipe fitting hydrostatic test water temperature and water quality have certain requirements, which shall not be less than 5 ° C water temperature; chloride ion content in water shall not be greater than 25Pmm.
