SS ERW Pipes & Tubes
Stainless steel is an alloy made of steel with a chromium base. Mixing steel with other components such as chromium, molybdenum, copper, silicon, carbon, and aluminum makes an alloy called stainless steel. Stainless steels are designed materials providing strong resistance to corrosion, power, and properties of production.
Pipes and tubes manufactured from different grades of stainless steel are common on the market and are sold according to use and form of user. In piping, various types of stainless steel are used. Because of its outstanding corrosion resistance properties, Stainless Steel is the most commonly used commodity in Process industries.
ERW Pipes are manufactured by method of electric resistance welding. Though weaker than seamless, ERW pipes are good options for low pressure and civil applications. 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.
A stainless steel welded pipe is cold rolled flat strip or sheet and then made circular using a bending machine. Stainless steel ERW pipe can be welded with or without filler material utilizing a high source of energy. These pipes can be produced in customize sizes without any restrictions. The SS welded pipe can work well in moderate corrosive environments due to the presence of welds. The economically welded stainless steel pipe is simpler to procure and produce. These ERW pipes have a good surface quality and have a consistent wall thickness. Stainless steel welded round pipes are used in the transportation of water, oil, and gas in larger quantities.

Riddhi Siddhi Impex is a leading Stainless Steel Erw Pipe manufacturers, exporter and supplier 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.
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.
