Shandong Q235B small diameter oxygen blowing tube

WeldingSteel pipeAlso known as welding pipes, it is made fromSteel plateOrCoil SteelAfter being curled and shaped, the steel pipes are usually cut to a standard length of 6 meters.Welded Steel PipeThe production process is simple, with high efficiency, a wide variety of specifications, and low equipment investment, but generally lower strength than expected.Seamless steel tube。

Since the 1930s, withSteel StripThe rapid development of continuous rolling production and advancements in welding and inspection technologies have led to continuous improvement in weld quality. The variety and specifications of welded steel pipes are increasingly diverse, and they are replacing them in an ever-growing number of fields.Seamless Steel PipeWelded steel pipes are classified according to the type of weld.Seam Welded PipeAndSpiral Welded Pipe.Categorized by production method: Process Classification - Arc Welded Pipe, Resistance Welded Pipe, (High Frequency, Low Frequency) Gas Welded Pipe, Furnace Welded Pipe.

Small-diameter welded pipes are typically made using straight seam welding, while large-diameter welded pipes usually employ spiral welding; pipes are categorized by the shape of their ends into round welded pipes and non-standard (square, rectangular, etc.) welded pipes; and they are further divided by material and application into mining fluid transportation weldingSteel pipeGalvanized welded steel pipes for low-pressure fluid conveyance, belt conveyor roller electric welded steel pipes, etc. Sorted by outer diameter * wall thickness, as per the specifications and dimensions table in the current national standards.
