  1. Stainless Steel Tees can not be directly contacted with other metals during transportation, and need to be padded with non-metallic materials such as wood or rubber plates.

  2. The arc-starting and arc-closing and arc-starting of Stainless Steel Tees shall be done by back-welding method, and the arc-closing shall be filled with arc pits. The Stainless Steel Tee shall be completed in the groove, and arc-striking and arc-starting shall be prohibited on the surface of pipes and pipe base materials. If defects such as blowhole and crack are found at arc initiation and arc closure, they should be dealt with in time.

  3. The arc-starting and arc-closing points of multi-pass and multi-layer welding of Stainless Steel Tees should be staggered.

  4. The connection of Stainless Steel Tees, fittings, stainless steel pipes and fittings with non-Stainless Steel Tees and fittings. Before welding butt joint, the pipe and cavity should be filled with argon gas protection before bottom welding.

  5. When ASTM A403 WP904L Stainless Steel Pipe Fitting Tee are welded continuously, the interlayer temperature should not exceed 60 C.

  6. Argon filling protection should be applied to the inner weld of Stainless Steel Tees and fittings during positioning welding.

  7. General grinding wheel is not allowed to cut Stainless Steel Tees. Special grinding wheel or plasma cutting should be used for Stainless Steel Tees cutting.

  8. The weld seam of Stainless Steel Tees joints shall be pickled and passivated after welding.
