Jyoti Steels is a well-known producer and exporter of Duplex Tube Fittings located in Mumbai, India. We provide high-quality, precision-made fittings that have superior corrosion resistance, high mechanical strength, and consistent performance under harsh conditions. Our Duplex tube fittings are produced to international standards and find application in high-pressure and corrosive conditions. With a high emphasis on quality assurance, on-time delivery, and customer satisfaction, Jyoti Steels caters to a vast array of industries such as oil & gas, petrochemicals, marine, and chemical processing in India and worldwide.
Duplex Tube Fittings generally comprise approximately 22% Chromium, 5–6.5% Nickel, 3–3.5% Molybdenum, and 0.14–0.2% Nitrogen with other elements such as Manganese (≤2%), Silicon (≤1%), and Carbon (≤0.03%). They have very good mechanical properties with tensile strength varying between 620–880 MPa and yield strength of about 450 MPa. Their density is about 7.8 g/cm³ and melting point is about 1350°C. Due to their two-phase (ferritic-austenitic) microstructure, Duplex tube fittings have superior resistance towards pitting, crevice corrosion, and stress corrosion cracking, which qualifies them for aggressive and corrosive industrial applications.

Duplex Tube Fittings are extensively applied in industries where corrosion resistance and high strength are paramount. Typical applications range from offshore platforms, chemical processing plants, and oil refineries to desalination units. They find application in joining pipes and tubes in high-pressure systems for leak-proof and long-lasting connections. Duplex Tube Fittings are also suitable for marine environments because of resistance to chloride-induced corrosion. They are also used in the generation of power, pulp and paper plants, and pharmaceutical processes. Their high mechanical performance and extended service life make them a choice for mission-critical fluid and gas conveyance systems.
