AUSTENITIC STAINLESS STEEL WELDED PIPES
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.

stainless steel WELDED PIPES MANUFACTURER, STOCKHOLDER AND SUPPLIER

Stainless Steel is often Referred to as Corrosion-Resistant Steel – it does not stain, Corrode or Rust as easily as Normal Carbon Steel. It would however be misleading to say it is Corrosion-Proof. It differs significantly from standard Carbon Steel due to the amount of Chromium present, which limits surface Corrosion unlike Carbon Steel which will Rust when exposed to air and any moisture in the Atmosphere. Due to its Anti-Oxidation Qualities, Stainless Steel is often a Popular Solution.
Where low maintenance and corrosion resistance is required, stainless steel plates are a natural choice and are used in a diverse range of applications from modern Architecture for cladding or fascia’s, to the food hygiene industry due to its Anti-Bacterial Qualities. MAH Metal Inc., Supplies Stainless Steel in a wide variety of Grades and Aesthetic Finishes. There are many options available - for example adding carbon during the forming process will make the stainless steel more durable and stronger too.

At the start of the welded pipe manufacturing process so called slabs or billets are cast in a steel mill. Dependent on the external dimensions and wall thickness there are different methods of producing welded pipes and tubes: Electric Resistance Welding (ERW), Fusion Welding (EFW) and Double Submerged Arc Welding (DSAW). In the ERW and EFW manufacturing process welded pipes are formed by hot or cold rolling plate and welding the seam. In order to keep the outside (O.D.) surface of a welded pipe smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Scarfing from the inside (I.D.) welded flash is also possible. With a heat treating at the end of the manufacturing process the weld zone of the steel pipe can be made less visible. Due to the weld seam lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general welded tubes possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities

ERW pipes means Electric Resistance Welded Pipe. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usully for for high diameter. (cheapest process avaiable) ERW pipes means Electric Resistance Welded Pipes. 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.
