Product Description
Stainless Steel Electric Resistance Welded (ERW) pipes are a popular choice across industries due to their cost-effectiveness, strength, and versatility. These pipes are manufactured by rolling stainless steel plates or sheets and welding the seam using an electric resistance welding process, resulting in a strong and uniform joint. Stainless Steel ERW pipe are widely used in industries like oil and gas, petrochemical, water treatment, power generation, and construction. Their excellent corrosion resistance makes them ideal for transporting liquids and gases in both corrosive and non-corrosive environments. Additionally, their lightweight construction and smooth surface finish ensure efficient flow and easy installation.
One of the most commonly used grades for Stainless Steel ERW pipes is 304. Known for its excellent corrosion resistance and mechanical properties, 304 stainless steel is suitable for applications in mild environments as well as moderately aggressive conditions. For enhanced resistance to pitting and chloride-induced corrosion, 316 stainless steel is often used, especially in marine and chemical processing industries.
These pipes are available in a variety of sizes, wall thicknesses (schedules), and lengths to meet diverse application requirements. They conform to international standards such as ASTM A312, ensuring precise dimensions and consistent quality. Stainless Steel ERW pipes undergo rigorous testing, including hydrostatic testing, ultrasonic testing, and chemical analysis, to meet safety and performance standards.
The advantages of Stainless Steel ERW pipes include high strength, excellent weldability, and low maintenance. They offer a cost-effective solution without compromising on quality, making them a preferred choice for structural and fluid transport applications.
