Stainless steel welded pipe processing technology

welding:
Before the stainless steel welded pipe is processed and welded, the rust, oil, water, paint, etc. that are harmful to welding should be completely removed, and the welding rod suitable for the steel type should be selected. The processing time of stainless steel welded pipe is shorter than that of carbon steel spot welding, and stainless steel welded pipe brush should be used to remove welding slag. After welding, in order to prevent local corrosion or strength reduction, the surface should be ground or cleaned.
Cutting and stamping of stainless steel welded pipe:

Because stainless steel welded pipes are stronger than ordinary materials, higher pressure is required for stamping and shearing, and poor shearing and work hardening will not occur when the gap between the knives and knives is accurate. Cutting with plasma or laser, when you have to use gas cutting or When the arc is cut off, the heat-affected zone is ground and, if necessary, heat-treated.

Processing and bending of stainless steel welded pipe:
The thin plate can be bent to 180, but in order to reduce the cracks on the curved surface, if the radius is 2 times the thickness of the plate, the radius of the stainless steel welded pipe is 2 times the thickness when it is processed along the rolling direction, and it is 4 times the thickness when it is bent perpendicular to the rolling direction. The radius is necessary, especially when welding, and the surface of the welded area should be ground for cracking.
Stainless steel welded pipe processing construction and construction attention points
In order to prevent scratches and pollutants from adhering to stainless steel welded pipes during processing, the construction of stainless steel welded pipes is carried out under the state of film sticking. However, as time goes on, the residue of the paste liquid should be cleaned according to the service life of the film. When removing the film after construction, the surface should be washed, and special stainless steel welded pipe processing tools should be used. When cleaning public tools with general steel, in order to prevent iron filings from sticking Clean up.
Care should be taken not to allow highly corrosive magnetic and stone luxury cleaning drugs to contact the surface of the stainless steel welded pipe, and the stainless steel welded pipe should be washed immediately when processing. After the construction is completed, use neutral detergent and water to wash the cement, powder ash and other objects attached to the surface.
