Steel Sales Company is one of the biggest supplier, manufacturer, exporter of Duplex Steel Threaded Flanges, with different grades such as Duplex Steel Werkstoff No 1.4462 Threaded Flanges, Duplex 2205 Threaded Flanges, Duplex UNS S32205 Threaded Flanges, Duplex Steel S31803 Threaded Flanges, Duplex Steel ASTM A182 Threaded Flanges, Duplex Steel ASME SA182 Threaded Flanges, ANSI/ ASME B16.5 B16.5 Duplex Steel Threaded Flanges and other Duplex Steel Threaded Flanges in India. Duplex Steel Threaded Flanges that give a driving force to organizations working in various verticals, and helping them venture into different zones.The most essential element of these ribs is that they can be joined to a channel without welding. The drag of Nickel Threaded Flanges have strings and can be fitted to pipes that have outside strings. The addition of molybdenum and slightly higher nickel content make Duplex Steel S31803 Blind Flanges suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures. Duplex Steel UNS SS3180300 Socket Weld Flanges also offer higher creep, stress – to – rupture and tensile strength at elevated temperatures, excellent corrosion resistance, and strength properties, and they are well suited for fabricated or formed applications. Duplex Steel Threaded Flanges are low valued, fit best for little funnels, and can be utilized in low-pressure applications. They are advantageous in exceptionally burnable enterprises where welding is risky. Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. Female Threaded Flange might be welded around the joint after get together, however, it isn’t viewed as an agreeable strategy for expanding its applications. Duplex steel Threaded pipe flanges dimensions are usually used with pipes that have external threads. ASTM A182 duplex steel Threaded Flange are stocked or available in the following range of sizes and materials for the petrochemical, oil, gas, and allied industries. These Duplex Steel Werkstoff No 1.4462 Threaded Flanges can be obtained by us in customized sizes and dimensions with respect to national and international standards.
Flanges:
Flanges are connection bolsters utilized in a pipeline to attach two significant pipelines. With the mechanical help of the flanges, a consistent equipment design can be provided to the pipeline. For supporting a more prominent mass, a heavier rib body is required. The basic quality given by the flanges is an incredible architectural strength required in the pipeline structure.

- Raised Face: The concept of raised face is to establish more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.
- Ring Type Joint: They are applied for high pressure, high-temperature application with an “initial line contact” mechanism served by the metallic ring gaskets.
- Flat Face: Mostly flat facing is applied on flanged ends, which are produced from castings or fiberglass. Flat Face flanges are never to be bolted against a raised face or any other.
- Male Female Joint: They are commonly used for high pressure and high-temperature services
- Tongue and Groove: Prominently found on flanged pump covers and valve bonnets. Also used for high temperature and high-pressure applications

Production Of Flanges
We have world-class machinery for flanges manufacturers. We have CNC, Lathe Machines as well as punch dyes required for manufacturing of flanges. The forgings are outsourced. We have in house testing facilities like Spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge. Our product range also includes pipe fittings and fasteners which are considered piping accessories for a pipeline set up. The production Raw material is subject to heat-treatment for optimum use of a dye for processes ahead. Then the flanges are made as per dimensions specified in the ANSI Standards with a hub or without the addition of the hub. Then the flanges are machined and finished and then the marking process of the flanges is done.
Quality Control:
Steel sales Co is certified by all the renowned certificates including ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 & CE-PED 97/23/EC. We guarantee the best quality for all the fittings manufactured as they are checked in the workshop for defects in quality and technique. Our quality program is a 3 step independent department check for various factors, including Dimensional Check, Visual Inspection, and Finishing, Burr level, Leakage Test, Pressure Rating test, Chemical inspection, and Mechanical properties verification.
