Various Types Of Super Duplex S32760 Tube

Super Duplex 2507 Seamless tubing

Super Duplex S32760 Seamless Tube

Super Duplex S32760 Seamless Tube 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. Super Duplex S32760 Seamless Tubes don’t have a weld seam. In Super Duplex S32760 Seamless Tube, there are no welding or joints and is manufactured from solid round billets. Super Duplex S32760 Seamless Tube is manufactured by extruding the metal to the desired length and does not have any joint in its cross-section throughout its length.
Super Duplex S32760 Seamless Tube is finished to dimensional and wall thickness specifications in tube sizes from 1/8 inch to 26 inch OD. Oshwin Overseas is one of the leading seamless Tube manufacturer in India. We are specialized in Seamless Tube manufacturing. Seamless Tubes have better ovality, or roundness than welded Tubes.

Super Duplex 2507 Welded Tube

Super Duplex S32760 Welded Tube

Super Duplex S32760 Welded Tube is made of 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.
Super Duplex S32760 Welded Tube is typically more cost-effective than their Super Duplex S32760 Seamless equivalents. Super Duplex S32760 Welded Tube is usually more readily available than Super Duplex S32760 Seamless. The longer lead time required for Super Duplex S32760 Seamless Tube can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate. The internal surface of Super Duplex S32760 Welded Tube can be checked before manufacturing, which isn’t possible with Super Duplex S32760 Seamless Tube.
