Since the 1930s, with the rapid development of continuous rolling production of excellent strip steel and the progress of welding and inspection technology, the weld quality has been continuously improved, the varieties and specifications of stainless steel welded pipe have increased day by day, and seamless steel pipe has been replaced in more and more fields. The following editor will introduce the specifications and types of stainless steel welded pipes:
Stainless steel welded pipe is divided into straight seam stainless steel welded pipe and spiral stainless steel welded pipe according to the form of weld.
The strength of spiral stainless steel welded pipe is generally higher than that of straight seam stainless steel welded pipe. It can produce stainless steel welded pipe with larger pipe diameter with narrow blank, and stainless steel welded pipe with different pipe diameter with blank of the same width.
However, compared with the straight seam pipe with the same length, the weld length increases by 30 ~ 100%, and the production speed is low.
Small diameter stainless steel welded pipe adopts straight seam welding, while large diameter stainless steel welded pipe mostly adopts spiral welding; According to the shape of the end of the steel pipe, it is divided into circular stainless steel welded pipe and special-shaped (square, rectangular, etc.) stainless steel welded pipe.
Classification by production method: process classification - arc stainless steel welded pipe, resistance stainless steel welded pipe, (high frequency, low frequency) gas stainless steel welded pipe, furnace stainless steel welded pipe. Straight seam stainless steel welded pipe has the advantages of simple production process, high production efficiency, low cost and rapid development.
According to different materials and uses, it is divided into welded steel pipe for mining fluid transportation, galvanized welded steel pipe for low-pressure fluid transportation, electric welded steel pipe for belt conveyor idler, etc.
According to the specification and size table in the current national standard, it is sorted from small to large according to the outer diameter * wall thickness.
The above information is the analysis and introduction of the specifications and types of stainless steel welded pipes. I hope you can have a further understanding of stainless steel welded pipes.
