Welded steel pipe

Also called a welded pipe, it is cut into narrow steel bars by steel strips, and then cold-wrapped into a tubular shape by a mold. The special welder then welds a pipe joint. The outer weld is polished and bright. The inner burr of a general welded pipe is not hit. Only the precision welded pipe is used to make internal burrs.
Anti-corrosion: The welded steel pipe refers to a steel pipe with a seam on the surface and a steel or steel plate that is bent and deformed into a circular shape or a square shape. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe and so on. According to the shape of the weld, it can be divided into a straight welded pipe and a spiral welded pipe. Electric welded steel pipes are used in oil drilling, machinery, and manufacturing. The furnace welded pipe can be used as a water gas pipe, etc., the large diameter straight seam welded pipe is used for high pressure oil and gas transportation, etc.; the spiral welded pipe is used for oil and gas transportation, pipe piles, piers and the like. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes.
high-frequency resistance seam of the junction box. Just OK. The bend can be used to bend the corresponding curvature in the pipeline.
