  • Welded & Cold Rolled Stainless Tube

    Welded & Redrawn/Rerolled Stainless Tubes

    Our weldrawn tube manufacturing process begins with cold rolled strip of metal, roll formed into tubular shape and seam welded without the use of any filler material. The as-welded tube is then reduced in size a number of times through various cold working techniques until reaching the exact size, tolerances, and temper our customers require.

    After each cold working cycle the tubes are cut, cleaned and heat treated in preparation for the next cold working step. Before reaching final size, our weldrawn products will undergo a minimum of two draw cycles reducing their cross-sectional area by at least 40% after welding.

    Our manufacturing process employs a combination of value-added steps to produce the highest quality tubing that meets the exact specifications supplied by our customer. Tubes can be created in a variety of different sizes and shapes from a wide range of alloys. A brief description of the operations we use during production can be found below.

  • Super Long Seamless Stainless Coil Tube

    The seamless stainless steel coil tubes are used for a variety of circulation systems for different gases and fluids, coil tubes provide the ability for long length tube installations without the need for joining fittings. Baosheng offeres both welded and seamless coil tubes and can provide them in long mill lengths or cut-to-length in sections as short as fifty feet. These products have industry applicability for petrochemical, oil production heat tracing, geothermal and flow measurement applications.

    Oil & Gas – Chemical injection and hydraulic control lines in downhole and subsea applications. Our tubing has helped some of the most well-known oilfield service companies reduce operating costs and improve efficiencies.

    Chemical Processing – When critical fluids are transferred in a chemical process environment our seamless tube eliminates the potential of a filler material to flake off and get trapped, resulting in inaccurate measurements or an overall system breakdown.

    Alternative Energy – Coiled tubing for Hydrogen Refueling Stations, CNG Transfer, LNG Transfer, Geothermal and Solar Dishes.

    Aerospace & Defense – We provide high grade MIL-Spec seamless stainless steel tube for applications such as Airframes, Fuel Lines, Gas Return Tubes for Automatic Weapons and Hydraulic Lines.
