SS ERW Tube and Stainless Steel EFW Pipe Supplier in India

Stainless Steel Welded Pipe

ASME SA312 ERW Pipe comes under the specification and it cannot be made up of diffrent grade of materials. The most common elements are manganese, carbon, silicon, phosphorus, sulfur, chromium, molybdenum, nickel and nitrogen. The grades used can be 304, 309, 310, 316 and so on with their different carbon variations. The Laser Welded Stainless Steel Tubes  have higher outer diameters in comparison to the seamless pipes made through cold drawing or hot rolling. The pipes can also be made from alloy steels and duplex steel grades. We are Stainless Steel Welded Pipe Supplier in India from last 15 Years. The diameter of the pipes ranges from 1/8 inches to 36 inches. These pipes are specified for high temperature, high pressure services. The stainless steel grades and others can be used as the ASTM A213 Heat Exchanger Tube as well.

The heat exchanger tubes are specifically made for the heat transfer purpose and there are certain specific types such as the U tubes which are used exclusively with heat exchangers. The Stainless Steel Welded Pipes are used in high strength applications due to the ease of welding. The low carbon content in these pipes make it easier for welding and eliminate the chromium carbide precipitation during welding. The ASTM A249 Stainless Steel High Pressure Tube is used in applications such as pressure vessels, power generation plants, heat exchangers, boilers and in some oil and gas industrial applications as well. The strength of the pipes varies from grade to grade. The minimum yield strength of the pipes range from 205 MPa and above.

ERW vs EFW Stainless Steel Pipe

Characteristic EFW ERW
Manufacturing Method Welded using electric arc Welded using resistance heat
Diameter Range Larger Smaller
Wall Thickness Range Thicker walls thinner walls
Cost High Low
Disadvantages Slower production for large sizes Limited to smaller thickness and diameter
Advantages Suitable for high pressure uses Suitable for small to medium sizes and cost-effective
Suitable Applications Higher pressure and temperature Lower pressure and temperature
