ASTM A182 F91 Flanges And SA 182 Grade F91 Weld Neck/ Slip On/ Blind

Specification Chart Of Alloy Steel F91 Blind Flanges And We Keep Bulk Stock Of SA182 F91 Weld Neck Flange In India.

The ASTM A182 specification of the flanges includes alloy steel (manganese, silicon, sulfur, chromium, and molybdenum) and is of the grade F91. The ASTM A182 F91 Flanges are available in different face types, like ring-type joints, flat faces, and raised faces. We are one of the top manufacturers of different kinds of Alloy Steel F91 Pipe Flanges, each of which has different applications in various industries:

Our SA 182 Grade F91 Weld Neck Flange is used in high pressure that either has high or low temperature. To use it, the piping system should have an unrestricted flow of liquid. Here the flange’s bore would match up with the pipe’s bore.

We also produce A182 F91 Type 2 Blind Flanges used for res\tricting the flow to a section of the pipe, not in use.

The Alloy Steel F91 Slip On Flange is like rings placed on the end of the pipes. These are used for fluids at a low pressure that has less risk of leakage.

Our SA182 F91 Type 1 Socket Weld Flanges are widely used in pipes with a smaller diameter, generally in those whose nominal diameter is less than or equal to NPS 2.

We also supply SA182 Gr F91 Plate Flange, which helps in ensuring the perfect seal between two joining pipes.
