Seamless Stainless Tubes & Pipes

  • Electro Polished Stainless Steel Tube

    Electro Polished is a “reverse plating” process that uses an electrochemical solution to remove the outer layer of stainless steel pipe. By stripping away a uniform layer of stainless steel tube, the electropolishing process also removes embedded contaminants, heat tint and oxide scale, micro cracks, burrs, pits, and other surface defect that can compromise the performance and durability of a part

     

    Electropolished Stainless Steel Tubing is especially done on 300 and 400 series stainless steel that improves a part’s corrosion resistance which leaves a lasting bright finish. Unlike passivation electropolishing can be performed on all varieties of stainless steel which gives its parts of all kinds corrosion resistance superiorto passivation alone—electropolished parts are 30 times more corrosion resistant than those that are passivated. The process of dissolving a uniform layer of surface metal is more effective and aggressive, because it is highly controlled and it can be used to remove as little as .02″ of surface material.

  • Small Rectangular Stainless Tube

  • Small Square Stainless Tube

    Stainless steel square tube and rectangular tube is commonly referred to as tube steel or structural tubing. These are also referenced as a hollow structural section or HSS for short. Used for structural purposes, square tube, rectangular tube, I beams, etc., can be purchased in many different types of steel and alloys. Manufacturing of square tube is the same as the manufacturing process of pipe but the product goes through a series of shaping stands, meeting its final square specifications.

  • 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.

  • High Precision Stainless Tube

    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.
