METLINE Industries is a leading manufacturer, exporter, and supplier of buttweld seamless and welded Duplex fittings, Duplex flanges, and Duplex pipes in Agra. We provide a complete range of Duplex stainless steel pipe fittings, including reducers, elbows, tees, crosses, stub ends, and pipe bends. As one of the few Indian manufacturers with in-house welding, bending, and forming capabilities, we can produce Duplex pipe fittings in a wide variety of sizes and dimensions.
Duplex stainless steels, with a Pitting Resistance Equivalent Number (PREN) of ~35, offer superior corrosion resistance compared to 304 (PREN 19) and 316 stainless steels (PREN 26), particularly against stress corrosion cracking.
Our Duplex flanges are available in a broad range of sizes and pressure ratings, designed to meet project-specific requirements. Duplex pipes and fittings from METLINE are widely used in industries such as boiler manufacturing, brewing tanks, and desalination plants.
Duplex stainless steel products are generally more cost-effective due to their lower alloy content while providing higher yield strength than austenitic stainless steels. This allows the same performance with thinner Duplex pipes and fittings, resulting in material and cost savings.
In addition to fittings and flanges, METLINE stocks and supplies a full range of Duplex seamless pipes, available in cut-to-length sizes, and can be machined or fabricated to meet specific customer piping requirements.
