Submerged arc steel pipe welding control measures:Submerged arc steel pipe has become the steel pipe for large-scale oil and gas transportation projects at home and abroad due to its large wall thickness, good material, and stable processing technology. In large-diameter submerged arc steel pipe wel

Pre-welding of straight seam steel pipes: Pre-welding includes joints and welds.1. There is no wrong edge or the wrong edge is smaller than the specified value. Generally, the amount of the wrong edge is ≤8% of the plate thickness, and the maximum is not more than 1.5mm.2. It is necessary to ensure

Straight seam steel pipes need to be matched with a product in the production process, that is, glass lubricant. Before using glass lubricant, it was produced with graphite, because there was no such product on the market at that time. Therefore, graphite can only be used as a lubricant, but after l
