Stainless steel welded pipe production process

Stainless steel welded pipe manufacturers steel plate ultrasonic flaw detection: used to produce large diameter self-seam submerged arc welded steel pipe steel plate into the production line, the first full plate ultrasonic inspection; both sides of the steel plate milling: through the milling machine on both edges of the steel plate double-sided milling, so that it arrives at the required plate width, edge parallelism and bevel shape.

Stainless steel pipe welding: selection of longitudinal multi-wire submerged arc welding (up to four wires) in the stainless steel pipe welding; stainless steel pipe welding: selection of longitudinal multi-wire submerged arc welding in the stainless steel pipe welding outside the submerged arc welding; stainless steel welded steel pipe table inside the weld and weld both sides of the parent material for 100 percent of the review; table inside the weld for 100 percent of the X-ray Industrial TV review, the choice of image processing system to ensure the viability of the flaw detection.

Stainless steel welded pipe manufacturers stainless steel pipe expansion: submerged arc welded stainless steel pipe expansion of the full length of the pipe to advance the precision of the scale of the steel pipe, and improve the distribution of stress in the shape of the steel pipe; in the hydraulic testing machine after the expansion of the steel pipe root by root check to ensure that the steel pipe to reach the standard requirements of the test pressure, the machine has an automatic record and storage function.

Stainless steel stainless steel welded pipe chamfering: the inspection and qualified steel pipe end processing, to reach the required pipe end bevel scale; again root by root ultrasonic inspection to review the stainless steel straight seam welded steel pipe in the expansion, hydraulic pressure can be the onset of the shortcomings; after the expansion and hydrostatic test of the steel pipe for X-ray industrial television review and pipe end weld filming.
