What is Precision Stainless Steel Welded Pipe?

Precision stainless steel welded pipe is a type of straight-seam welded pipe known for its precise surface or dimensions. It is made by extruding steel strips through molds and then welding them automatically or manually. This pipe is simple to size, highly efficient to produce, and comes in various specifications, making it commonly used in machinery, furniture, sanitary ware, appliances, and engineering components. Different applications require varying degrees of precision.

Key Features of Precision Stainless Steel Welded Pipes:

1. Smooth Surface: For applications such as furniture and sanitary ware, a high surface smoothness is required. Methods like mechanical or electrochemical polishing can achieve a mirror effect with a Ra value of around 0.8μm, ensuring minimal scratches, rust, and pitting.

2. Perpendicularity: For electronic and electrical housings, the perpendicularity of the weld pipe is crucial. A computer-controlled process detects and corrects any bending, ensuring accurate straightening through hydraulic pressure.

3. Ovality: Mechanical components may require precision drilling or slotting on the pipe body, which can deform the pipe. Laser technology prevents deformation during these processes, ensuring high conformity between the stainless steel pipe and molds.

Precision stainless steel welded pipes are characterized by their high surface smoothness, precise perpendicularity, and minimal ovality. They are manufactured through processes like welding, polishing, cutting, and drilling, combined with material selection and precision molds, resulting in pipes with uniform wall thickness and accurate dimensions.
