Forged Steel Socket Pipe Fittings Installation Considerations

Forged Steel Socket Pipe Fittings installed mainly in the following nine notes:
1, forged steel pipe fittings material lifting, not in direct contact with other metals, wood or rubber should be padded panels and other non-metallic materials.
2, stand tube cutting is not allowed with ordinary grinding wheel cutting, grinding wheel for stainless steel should be used or plasma cutting.
3, stainless steel pipes and pipe rack positioned inside seam welding should be carried out when the argon protection.
4, with the closing arc arc, arc welding method using the back, closing the arc should be filled crater. Arc must be completed within the groove, banned in pipes, fittings and the base metal surface arcing arcing. If the arc and arc found at the closing holes, cracks and other defects should be promptly dealt clean.
5, forged branch outlet fittings ,forged steel pipe fittings and non-pipe rack pipe connections, welded butt joints before welding primer tube and the cavity should be filled with argon gas to perform TIG welding.
6, multi-channel multi-arc welding, arc at the closing should be staggered.
7, continuous welded stainless steel pipe rack, its interlayer temperature does not exceed 60 ℃.
8, pipe connections at the weld seam after welding to pickling and passivation.
9, forged steel pipe fittings hydrostatic test water temperature and water quality have certain requirements, the water temperature is not less than 5 degrees Celsius; chlorine ion content shall not be greater than 25Pmm.
