Welcome to attent the Tube Fair From 14 to 16 June 2023 and Wish we could meet there, do remember that our booth number is W4E08
  • ERW rectangular tube

    ERW rectangular tube

    Hollow seaction refer to metal materials with a hollow cross-section. Compared with solid profiles, hollow sections are lighter, but have better performance in terms of load-bearing capacity and high strength. Rec-tube and square tube are common HSS. According to the raw materials, it has two different types: carbon and stainless steel.
  • Manufacturing Process of ERW Pipe-China Steel Pipe

    Manufacturing Process of ERW Pipe-China Steel Pipe

    ERW steel pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
  • Breaking Down Common Steel Tube Processes and Finishes- Welded Steel Pipe

    Breaking Down Common Steel Tube Processes and Finishes- Welded Steel Pipe

    Abbreviated ERW, this is a format that signals a specific welding process – actually two processes, spot and seam welding. This process involves several specific steps where the steel is unwound and trimmed, then passed through rollers to cold-form the steel into the proper shape (circular, square or rectangular).From here, the edges are forced together into a butt joint, then welded at a very high temperature to form a flash weld. Once the weld is tested, the tube passes through various sizing rolls to achieve the proper size, and then the length is cut. The materials used here will generally be available in both hot-rolled and cold-rolled formats.
