Duplex Steel Fittings-flanges-ManufacturerVishal Steel India is leading Manufacturer of duplex steel pipe fittings & duplex steel flanges in INDIA since Five Decades,Vishal Steel India ranks in Top Ten company in INDIA engaged in manufacturing of stainless steel buttweld fittings, carbon steel buttweld fittings, alloy steel buttweld fittings, cupro nickel buttweld fittings, nickel alloy buttweld fittings and duplex stainless steel buttweld fittings. While, there are many specialised types of fittings which can be manufactured, the most common types of fittings which we manufacture include duplex pipe elbow, tee, reducers, cap, duplex stub ends and special size duplex pipe bends in both seamless and welded (100% X-Ray Tested/Radiography) form.

Alloys 254 / 254 SMO / 6 Mo is an austenitic stainless steel with a high molybdenum content. Coupled with Nickel and Copper this gives the alloy a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.

254 SMO (UNS S31254) may offer a cost effective solution to Nickel and Titanium alloys in these environments.

Duplex Steel Fittings-flanges-ManufacturerWe design and manufacture a wide array of duplex steel pipe fittings,duplex steel flanges, duplex forged pipe fittings as per our Customer’s requirements. We take Buy-Back Guarantee of Our duplex steel pipe fittings & duplex Steel Flanges If they happen to be flawed. we buy best quality & multi level tested raw materials to manufacture duplex Steel Fittings & duplex Steel Flanges We Are Backed By Technologically Advanced Infrastructure and A Team Of highly Professional engineers having experience in manufacturing of duplex steel pipe fittings & duplex steel flanges, Today, We are exporting duplex steel pipe fittings & duplex steel flanges to more than 40 countries like UAE, EGYPT, TURKEY, Singapore, Malaysia, Iran, Iraq, Saudi Arabia, Bahrain, Qatar, yemen, Kuwait, Argentina, Palestin, Algeria, Italy, Tunisia, Oman, Mauritania, USA, Bangladesh, Lebanon, Canada, Vietnam, INDIA, Sudan, Syria, Morocco, Libya, Jordon,etc. Vishal Steel India is a leading manufacturer, exporter and supplier of buttweld seamless and welded duplex fittings, duplex flanges and duplex Forged. we 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 manufacturer 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.

At Vishal Steel India 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.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.
