Welded Pipes Manufacturer
At Steel Icon Stainless Pvt. Ltd., we manufacture and supply high-quality welded pipes engineered for strength, corrosion resistance, and long service life in both high-pressure and low-pressure environments. Our welded pipes are available in ERW (Electric Resistance Welded), EFW (Electric Fusion Welded), and SAW (Submerged Arc Welded) formats, crafted using premium stainless steel, carbon steel, alloy steel, and duplex materials.
Our facilities are equipped to produce welded pipes that meet stringent international standards such as ASTM, ASME, DIN, EN, and ISO, suitable for diverse industries like oil & gas, construction, HVAC, chemical processing, food & beverage, water distribution, and marine engineering.
What Are Welded Pipes?
Welded pipes are manufactured by rolling and welding steel plates or coils into cylindrical shapes. The weld seam can be longitudinal or spiral, depending on the process. These pipes are commonly used in applications that require large diameters, cost-effectiveness, and high mechanical strength.
Welded pipes are available in a variety of types such as ERW, EFW, SAW, and LSAW, depending on the welding process and pressure rating.
