Stainless Steel Welded Pipe – The seamless stainless steel strip is fused into a single rolled shape under gas protection without the addition of filler material, ensuring uniform wall thickness.
Advantages of stainless steel welded pipe:
1. Uniform Wall Thickness - Made from formed strip material, boasting consistent wall thickness and a high degree of surface smoothness, reaching industrial clean finish level 2B.
2. Low residual stress - The formed steel pipes are subjected to a bright annealing process at a high temperature exceeding 1040 degrees Celsius to relieve stress in the stainless steel pipes.
3. High Weld Strength - Utilizing fusion welding, the material composition remains unchanged. After high-temperature heat treatment, the weld and base material possess the same intergranular structure. During destructive tests such as flattening, reverse bending, and expanding, no cracking or cracks, burrs, etc., will appear at the weld. Furthermore, eddy current testing and hydrostatic or pneumatic testing are conducted to ensure tube quality.
4. Consistency - The consistency of the pipe's outer diameter, wall thickness, length, and straightness is excellent, with high processing accuracy.
