Advantages of stainless steel welded steel pipe

Stainless steel welded steel pipe - Stainless steel strip with uniform wall thickness is welded in one roll without added solder under gas protection.

1. Uniform wall thickness -- the base material is molded strip, with good wall thickness consistency and high surface finish, reaching industrial net surface grade 2B.

2. Low residual stress -- after forming the steel pipe, the stainless steel pipe is annealed at a high temperature of higher than 1040 degrees to eliminate stress.

3. High weld strength - by fusion welding, welding material composition is changeless, after high temperature heat treatment between the weld and parent metal with the same crystal structure, the weld flattening, reverse the damage experiments such as bending, flaring, welds will not appear crack or cracks, burrs, etc. In addition to eddy current testing and water pressure or gas testing to ensure the quality of the pipe.
