ERW(Electric Resistance Welding)
ERW welded pipes are divided into ordinary welded steel pipes and low pressure flow welded steel pipes. The latter has an additional hydraulic test, and the price is also about 80 per ton higher than that of ordinary welded pipes. Mainly used for low-pressure fluid transmission pipelines such as steel structure engineering, machinery manufacturing, construction water and oil pipelines
Spiral welded pipe
Spiral welded pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into pipe blank according to a certain helix angle (called forming angle), and then welding the pipe seam. It can produce large-diameter steel pipe with narrow strip steel.
