Ramesh Steel Corporation also stocks and supplies a complete range of duplex seamless pipes to complement our existing production range of duplex buttweld fittings and flanges. Duplex pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.

Duplex stainless steel pipes and duplex fittings are generally lower in cost, as lower percentage of alloying element is used in the manufacture of duplex stainless steel. The yield strength of duplex stainless steel products is higher compared to austenitic stainless steel products, as a result of which users can purchase relatively lower thickness duplex pipes and duplex fittings.

Ramesh Steel Corporation is a leading manufacturers, exporters and suppliers of buttweld seamless and welded duplex fittings, duplex flanges and duplex pipes. Ramesh Steel Corporation offers a complete range of duplex stainless steel pipe fittings such as duplex reducer, duplex elbow, duplex tee, duplex cross, duplex stub ends and duplex pipe bends. We are one of the few manufacturers in India who can weld, bend and form duplex stainless steel pipe fittings in various sizes and dimensions.

With a PREN of around 35, duplex stainless steels are generally more corrosion resistant than 304 (PREN: 19) and 316 stainless steels (PREN: 26), particularly stress corrosion cracking.

Duplex flanges can be manufactured and supplied in a variety of sizes and pressure ratings to meet project specific requirements of our customers. Our duplex pipe and fitting products are widely supplied to many industries including boiler manufacturing, brewing tanks and desalination plants.
