Description of the relevant knowledge of the transportation and processing of stainless steel pipe fittings

1: Stainless steel pipe fittings are lifted and cannot be in direct contact with other metals. Non-metallic materials such as wood or rubber sheets should be added.
    2: Stainless steel pipe fittings are used for arcing and arcing, arcing is by reflow method, and arcing should be filled with arc pits. Arcing must be completed in the groove. It is forbidden to arc and arc on the surface of pipes and pipe fittings. If the arcing and arcing are found, defects such as pores and cracks should be cleaned in time.
    3: The arcing and arcing of multi-layer multi-layer welding of stainless steel pipe fittings should be staggered from each other.
    4: Stainless steel pipe fittings, pipe fittings and stainless steel pipes, pipe fittings and non-stainless steel pipes, pipe fittings, welded butt joints before welding, the inside of the pipe and the cavity should be filled with argon gas protection, in order to carry out tungsten argon arc welding.
    5: When the stainless steel pipe material is continuously welded, the interlayer temperature does not exceed 60 °C.
    6: When the stainless steel pipe fittings and pipe fittings are positioned, the inside of the weld should be filled with argon.
    7: Stainless steel pipe cutting is not allowed to be cut with ordinary grinding wheel. It should be made of stainless steel pipe special grinding wheel or plasma cutting.
    8: Stainless steel pipe fittings are connected to the welds at the welds, which are pickled and passivated after welding.
    9: Stainless steel pipeline hydraulic pressure test has certain requirements on water temperature and water quality. The water temperature should not be less than 5 degrees Celsius; the chloride ion content in water should not exceed 25Pmm.
