ASTM A182 Grade 347H Forged Flange

Stainless Steel 347 Flanges And ASTM A182 Grade 347H Forged Flange

ISO Approved SS 347H Blind Flanges Manufacturer In India And Check ASME SA182 347H Slip On Flange Bolt Size/ Length Chart/ Equivalent Chart.


We are one of the top PDO-approved manufacturers of stainless steel flanges in India. Our flanges are made of high-grade stainless steel and capable of withstanding critical environments. The Stainless Steel 347 Flanges we manufacture can be used at cryogenic temperature, high temperature, and high wear and tear applications. In addition, our SS 347 Flanges can be used in boilers and other heavy exhaust systems due to their excellent mechanical properties. We manufacture ASTM A182 F347 Flanges along with flanges of different specifications, such as A240. These flanges are forged, rolled, and can be used in high-pressure service applications.

We are a professional manufacturer and exporter of SS 347H Blind Flanges with precision machining facilities. According to the industrial standard, we produce these flanges in size range of 1/2 “ to 60” NPS. Apart from that, we also specialize in:

    • ASME SA182 347H Slip On Flange is mostly used in cooling water lines, firefighting water lines, low-pressure compressed airlines, etc.

    • Stainless Steel 347 Weld Neck Flanges are normally used in high and high/low-temperature environments. It is for application in those pipelines which require unrestricted fluid flow    in the piping system.

    • UNS S34700 Spectacle Blind Flange, a solid flange and used for blocking off a section of the pipe or nozzle on a vessel that is not used.

    • Werkstoff Nr. 1.4550 Large Diameter Flanges used to connect or block two pipes of large diameters.
