Duplex Steel Pipes & Tubes

Duplex Steel pipe and tubes are meant to outperform typical austenitic stainless steels like Type 304 or 316 in terms of corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, as well as strength. Intergranular and pitting corrosion resistance is enhanced by the chemical composition of Duplex Steel Seamless Pipes, which incorporates significant amounts of Cr and Mo. Nitrogen additions to Duplex Steel Welded Tubes can improve structural hardening through an interstitial solid solution process, increasing yield and ultimate strength without compromising toughness. Duplex Steel Welded Pipes and Tubes are used in a variety of industries, including the chemical, oil, and food industries, paper and pulp industries, pollution control industries, flow line pipe industries, and Christmas tree pipeline industries, and more.Specification of Pipes & TubesSpecification:- ASTM A790, A789 / ASME SA789, SA789Seamless Pipes & Tubes Size:- 1 / 8?
