Types of Super Duplex S32750 Pipe

Super Duplex S32750 Seamless Pipe

Super Duplex S32750 Seamless Pipe 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 S32750 Seamless Pipe don’t have a weld seam. In Super Duplex S32750 Seamless Pipe, there are no welding or joints and is manufactured from solid round billets. Seamless pipe is manufactured by extruding the metal to the desired length and does not have any joint in its cross-section throughout its length.

The seamless pipe is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Oshwin Overaeas is one of the leading Super Duplex S32750 seamless pipe manufacturer in India. We are specialized in Seamless Pipe manufacturing. Seamless pipe has better ovality or roundness than the welded pipe.

Super Duplex S32750 Welded Pipe

Super Duplex S32750 Welded Pipe are typically more cost-effective than their seamless equivalents. Super Duplex S32750 Welded Pipe is usually more readily available than seamless. The longer lead time required for the seamless pipe can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate. The wall thickness of Super Duplex S32750 welded pipe is generally more consistent than that of seamless pipe.

Super Duplex S32750 Welded Pipe 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. It is squeezed together and allowed to solidify, forming a weld bead.

Super Duplex S32750 ERW Pipe (Electric Resistance Welding)

Super Duplex S32750 ERW Pipe means Electric Resistance Welded Pipe. Super Duplex S32750 ERW Pipe is made from HR Coils. Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usually for high diameter. Super Duplex S32750 ERW pipe have a welded joint in its cross-section.

Super Duplex S32750 ERW Pipe is welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW pipe and tubes are used for various engineering purposes, fencing, scaffolding, line pipe etc. ERW steel pipe and tube are available in various qualities, wall thicknesses, and diameters of the finished pipe.
