Welded 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.

  • Stainless Oval Tube

    Because of their propensity to have extremely high ductility, stainless steel is favoured. Any oval stainless steel tubing’s ductility depends on its microstructure, which is a product of the metal’s alloying composition. Consider an alloy grade like 316 Stainless Steel Oval Tube as an example. The metal’s microstructure contains an austenite crystal. Nickel is a component of austenite’s alloy, which contributes to its formation and stability.

    Austenite has a face centre cubic microstructure, also known as an FCC, which makes the alloy of Flat Oval Stainless Steel Tube ductile due to the tightly packed atoms. Due to their ductility, austenitic stainless steels may be formed into a variety of shapes, from simple square, rectangular, and round shapes to more intricate ones like the Flat Sided Oval Stainless Steel Tube. In addition to being produced in a variety of shapes, stainless steel oval tubes can have variable diameters, wall thicknesses, and circumferences.

    The use of an oval tube has a number of advantages for users. For instance, stainless steel elliptical oval tubeshave a stronger construction and, despite being ductile, are more difficult to distort. Additionally, because to its extremely compact design, the majority of Oval Stainless Steel Tube Suppliers advise using these tubes in applications where there are issues with available space or where compact components are required.

  • 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.
