Types of Duplex Stainless Steel 2205 Tubes
Duplex 2205 Seamless Tubes is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. 2205 Duplex Seamless Tube don’t have a weld seam. In Duplex Seamless Tube, there are no welding or joints and is manufactured from solid round billets. Duplex Seamless Tube is manufactured by extruding the metal to the desired length and does not have any joint in its cross-section through-out its length.
Duplex Stainless Steel Seamless Tube is finished to dimensional and wall thickness specifications in tube sizes from 1/8 inch to 26 inch OD. Oshwin Overaeas is one of the leading seamless Tube manufacturer in India. Oshwin Overseas are specialized in Duplex 2205 Seamless Tube manufacturing. Seamless Tubes have better joviality, or roundness, than welded Tubes.
Duplex 2205 Welded Tubes is made by forming flat products (strip, sheet or plate) into the desired shape, in this case, normally round. Once the desired shape has been achieved, a high energy source is used to melt the metal locally at the weld joint. It is squeezed together and allowed to solidify, forming a weld bead. The high energy source may be an electric arc, a plasma arc, a laser beam, or even an electron beam.
Duplex Welded Tubes are typically more cost effective than their seamless equivalents. Duplex Stainless Steel Welded Tubes are usually more readily available than seamless. The longer lead time required for seamless Tubes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate. The wall thickness of Duplex 2205 Welded Tubes is generally more consistent than that of seamless Tubes.
