Duplex Steel Pipes

Midland Alloys is a trusted duplex stainless steel pipe manufacturer in India, known for high quality and consistent supply worldwide. Our duplex steel stainless pipes are made of Fe-Ni-Cr alloy with a ferritic-austenitic structure, which provides strength and corrosion resistance for demanding applications. Lower nickel content makes these pipes a cost-effective choice. Seamless pipes range in size from 4 mm to 219 mm, while duplex steel welded pipes range in size from 5 mm to 1219.2 mm. These pipes work well in high-pressure, high-temperature systems such as oil and gas, petrochemicals, and power generation. We offer duplex stainless steel pipe grades UNS S31803 and UNS S32205, which are designed for long-term performance.
