Types of Super Duplex S32750 Pipe

Duplex S32750 Seamless Pipe

Super Duplex S32750 Pipe – Seamless Stainless Seamless Pipe

Seamless Steel 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. Seamless Pipe don’t have a weld seam. In 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 through-out 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 seamless pipe manufacturer in India. We are specialized in Seamless Pipe manufacturing. Seamless pipes have better ovality, or roundness, than welded pipes.

Duplex S32750 Welded Pipe

Super Duplex S32750 Pipe – Welded Steel Pipe

Welded Steel Pipe 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.

Welded pipes are typically more cost effective than their seamless equivalents. Welded pipes are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate. The wall thickness of welded pipes is generally more consistent than that of seamless pipes. The internal surface of welded tubes can be checked before manufacturing, which isn’t possible with seamless.

Duplex S32750 ERW Pipe

Super Duplex S32750 Pipe – ERW Steel Pipe (Electric Resistance Welding)

ERW pipe means Electric Resistance Welded Pipes. ERW Steel 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 for high diameter. (cheapest process avaiable).  ERW pipe have a welded joint in its cross-section.

ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
