  • Product Description
    • what is a Welded tube?
    • Shineyond Group produces Welded tube with precision hollow structural components manufactured through high-frequency (HF) or submerged arc welding (SAW) processes, mainly round and square profiles. Round welded steel pipe is a steel pipe welded by crimping and forming a steel plate or steel strip, and the general fixed length is 6 meters. Welded square pipes are square pipes welded from steel plates or steel strips after being crimped. It can also be referred to as welded pipes for short.

      Excellent weld integrity combines for structural frames, mechanical systems, and fluid transfer applications. In addition, we offer value-added services, including custom cutting, bending, and post-weld heat treatment, to make our welding tube suitable for construction, automotive, oil/gas (API certified), and construction applications.

    • Production Process

      Welded pipes are formed by hot-rolled coils through a forming machine, which deform the steel coils into a smooth cylindrical shape. The edge of the tube blank is heated and melted by the collection effect and proximity effect of high-frequency current or the arc burning under the flux layer, and finally cooled and formed. Large-diameter or thicker welded pipes are generally made directly from steel billets, while small welded pipes and thin-walled welded pipes only need to be directly welded through steel strips. Then, after simple polishing and wire drawing, it is done.
