Stainless steel welded pipes processing is easy to cause certain changes to the inside or outside of stainless steel welded pipes. As a professional stainless steel welded pipe manufacturer, PMC summarizes some knowledge about stainless steel welded pipe processing for your reference:

Stainless steel welded pipe welding:

Before processing and welding stainless steel welded pipes, rust, oil, water, paint, etc. that are harmful to welding should be thoroughly removed, and an electrode suitable for the steel grade should be selected. 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 stamping:

Because stainless steel welded pipe have higher strength than general materials, higher pressure is required for stamping and cutting. When the gap between the knife and the knife 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 and bending:

The thin plate can be bent to 180 degrees, but in order to reduce the cracks on the curved surface, the stainless steel welded pipe with a radius of 2 times the thickness of the plate is given 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 and cracking of stainless steel welded pipes.

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 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. Clean up.Care should be taken to prevent the highly corrosive magnetism and cleaning agents from contacting the surface of the stainless steel welded pipe. 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, fly ash, etc. attached to the surface.
