SS 304 Welded Pipe, ASTM A312 316 Stainless Steel ERW Pipe manufacturer India
Oshwin Overseas is a leading Stainless Steel Erw Pipe manufacturer in India and we produce and sell different grades, types and sizes of the pipes. Our product range includes the most used SS 304 Erw Pipe products as well as the second most used SS 316 Erw Pipe products. The erw pipes are electric resistant welded from either strips or coils in a longitudinal direction to add strength to the pipe. There are different dimensions and standards of these pipes. The Erw Schedule 40 Pipe is one of the medium range schedules that allows medium range pressure containment of the pipes. The schedules govern the wall thickness for different outer diameter sizes of the pipes.
The Erw Stainless Steel Pipe can range from smaller sizes up to 24 inches outer diameter. Our Erw SS Pipes are manufactured according to international standards and are tested for quality. We also supply Erw Stainless Steel Tube & Stainless Steel Electric Resistance Welding Pipes in other material grades than the 304 and 316 grades of stainless steel. These pipes are mostly used in water, oil and other low pressure transportation of liquids. The advantage is the strength along the length of the pipes. For higher strength, the Stainless Steel Erw Square Pipe is used in some applications. Our Erw SS Pipe Standard is in accordance with the ASTM A312 Erw international standards. You can purchase ASTM A312 Tp304 Erw from us at competitive prices. Contact us for further information on Schedule 40 Erw Pipe or any other variations.

What will happen if you use a defected strip to produce an ERW pipe?
Electric resistance welding is a process of welding metal parts together by getting them to contact and heating them with electric current. This is one of the most widely used processes in making stainless steel pipes. In this method, the pipe is made from a strip of stainless steel material. The strip is curved into the pipe shape and the ends are touched where the electric current is passed to produce heat.
The both ends melt to form the joint. In case the strip used is defected, the contact might not be perfect when curving the strip to form the pipe. If the contact is not perfect, the pipe produced might have additional wall thickness as a result of improper alignment of the strip. Another possibility of defect strip usage is that it could leave space between joints where the ends do not touch each other properly and make a perfect contact.
These will result in a substandard pipe with enormous absolute roughness values and leakages. To avoid defect strips, the strips are stored and transported carefully prior to the electric resistance welding. The defects could also bring failure in strength, hardness and corrosion resistance calculations as well.
