Stainless steel welded pipes are tubular products manufactured by welding multiple stainless steel strips or coils. Union Steel Industry, a professional stainless steel welded pipe manufacturer, has compiled essential information regarding the processing of stainless steel welded pipes for your perusal.
Welding Procedure for Stainless Steel Welded Pipes:
Prior to commencing the processing and welding of stainless steel welded pipes, it is crucial to completely remove substances like rust, oil, water, and paint that could adversely impact welding. An electrode suitable for the grade of steel must be selected with care. The processing time frame for stainless steel welded pipes is shorter compared to carbon steel spot welding. A brush made of stainless steel is used to eliminate welding slag. After welding, it is crucial to either polish or clean the surface to prevent localized corrosion or strength reduction.
When cutting and stamping stainless steel welded pipes, higher pressure is required due to its superior strength compared to other materials. Precise gap adjustments between blades prevent subpar shearing and work hardening. For precise cutting, it is recommended to use plasma or laser methods. In cases where gas cutting or arc cutting is necessary, it is vital to perform subsequent heat-affected zone polishing and heat treatment.
Additionally, when bending stainless steel welded pipes, the appropriate techniques should be employed.
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 tube that is double 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 essential during welding, requiring the grinding of the welded area to prevent cracking in stainless steel welded tubes.
During the processing of stainless steel welded pipes, it is important to prevent scratches and contaminants from adhering.

During the processing of stainless steel welded pipes, it is important to prevent scratches and contaminants from adhering. To achieve this, construction is carried out in a film state. However, residues from the paste may adhere to the film over time. Thus, when removing the film after construction, it is necessary to wash the surface with specialized stainless steel welded pipe processing tools. Take care to avoid any contact between highly corrosive magnetic materials and cleaning agents with the surface of the welded stainless steel pipe. It is advisable to immediately wash the stainless steel welded pipe during the processing stage. After the construction phase, it is recommended that a neutral detergent and water be used to clean the surface of any cement, fly ash, or other materials that may be attached.
