Stainless steel welded pipe is a tubular product made of stainless steel strips or coils through multi-pass welding. As a professional stainless steel welded pipe manufacturer, Union Steel Industry has summarized some knowledge about stainless steel welded pipe processing for your reference.

 

Stainless Steel Welded Pipe


Welding Process for Stainless Steel Welded Pipes:

Before initiating the processing and welding of stainless steel welded pipes, it is imperative to thoroughly eliminate substances such as rust, oil, water, and paint that could detrimentally affect welding. An electrode appropriate for the steel grade should be carefully chosen. The processing time interval for stainless steel welded pipes is shorter compared to carbon steel spot welding. A stainless steel welded pipe brush is employed to remove welding slag. Post-welding, to forestall localized corrosion or strength reduction, it is essential to either polish or clean the surface.

 

Cutting and Stamping of Stainless Steel Welded Pipes:

Due to the higher strength of stainless steel welded pipes compared to general materials, elevated pressure is required for stamping and cutting. Accurate gap adjustments between blades help prevent poor shearing and work hardening. For precision cutting, plasma or laser methods are recommended. In instances where gas cutting or arc cutting is necessary, subsequent heat-affected zone polishing and heat treatment are vital.

 

Bending of Stainless Steel Welded Pipes:

Thin plates can be bent up to 180 degrees; however, to minimize cracks on the curved surface, it is advisable to provide a radius for the stainless steel welded pipe that is twice the thickness of the plate when bending in the rolling direction and four times the thickness when bending perpendicular to the rolling direction. Special attention is crucial during welding, necessitating the grinding of the welded area for the processing and prevention of cracking in stainless steel welded pipes.

 

Construction and Attention Points during Stainless Steel Welded Pipe Processing:

To prevent scratches and the adhesion of contaminants during the processing of stainless steel welded pipes, construction is carried out in a film state. Over time, residue from the paste may adhere to the film. When removing the film post-construction, it is important to wash the surface using specialized stainless steel welded pipe processing tools. Caution should be exercised to avoid contact between highly corrosive magnetism and cleaning agents with the surface of the stainless steel welded pipe. Immediate washing of the stainless steel welded pipe during processing is recommended. After construction, a neutral detergent and water should be employed to cleanse the surface of cement, fly ash, and other attached materials.
