It is widely used in many industries like petrochemical, oil, liquid and gas to check the flow by testing process. Blind flange dimensions are covered in ASME B 16.5 which also covers Pipe Flanges and Flanges size NP 1/2” to 24” for above NPS” to 60”. The specification for Stainless Steel is as ASMT A 182, A 240 with grades F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H and 904L. ASTM A 105, ASTM A 181 are the grades for carbon steel. ASTM A 182, GR F1, F11, F22, F5, F9, and F91 are grade for Alloy Steel. These products also come in Copper, Brass and Gunmetal. The class is differentiated by 150#, 300#,400 #,600#,900#, 1500# & 2500 #.

Pipe Fittings Supplier is a leading manufacturer, exporter and supplier of seamless and welded duplex fittings, duplex flangesand duplex pipes. Pipe Fittings Supplier 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. Our inventory for duplex seamless and welded pipes is one of the most extensive in the world. 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. Duplex & Super Duplex Fittings& Duplex Pipe provide very efficient corrosion control in the most demanding environments.
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.
Duplex stainless steel pipes and duplex fittingsare 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.
Pipe Fittings Supplier 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.
