Stainless steel welded pipe processing is easy to cause certain changes to the inside or outside of stainless steel welded pipes. As a professional manufacturer of stainless steel welded pipes for 10 years, New Gapower Steel summarized some knowledge about stainless steel welded pipe processing for your reference:

Welding:

Stainless steel welded pipe processing and welding should be thoroughly removed before welding rust, oil, moisture, paint, etc., which are harmful to welding, and select an electrode suitable for the steel type. The processing time interval of stainless steel welded pipe is shorter than that of carbon steel spot welding. 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 polished or cleaned.

Stainless steel welded pipe processing, cutting and punching:

Because stainless steel welded pipes have higher strength than general materials, higher pressure is required for stamping and cutting. When the knife-to-knife gap is accurate, poor shearing and work hardening will not occur. Plasma or laser cutting is used. When gas cutting or gas cutting is necessary When the arc is cut off, the heat-affected zone is polished and heat treatment is necessary.

Stainless steel welded pipe processing equipment

Stainless steel welded pipe processing and bending:

The thin plate can be bent to 180, but in order to reduce the cracks on the curved surface that is twice the thickness of the plate with the same radius, the stainless steel welded pipe is processed with 2 times the thickness of the plate in the rolling direction, and 4 times the thickness of the plate when bent in the direction perpendicular to the rolling. The radius is necessary, especially when welding, the surface of the welded area should be ground for the processing of stainless steel welded pipe cracks.

Stainless steel welded pipe processing construction and construction attention points

In order to prevent scratches and adhesion of contaminants during the processing of stainless steel welded pipes, the construction of stainless steel welded pipes is carried out in the film state. However, as time goes by, the residue of the paste is in accordance with 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 with general steel tools, in order to prevent iron filings from sticking Clean up.

Care should be taken to prevent the highly corrosive magnetism and stone luxury cleaning chemicals from contacting the surface of the stainless steel welded pipe, and the stainless steel welded pipe should be washed immediately during processing. After the construction is completed, neutral detergent and water should be used to wash the cement and fly ash attached to the surface.
