Standard Specification Of SS Blind Flanges And ASTM A182 F304 Blind Flange Price List/ Dimensions Class 150 To 2500.
The primary purpose behind using a blind flange is to block off the section of a pipe or nozzle that is not in use. The Stainless Steel Blind Flange helps in terminating the end of a piping system. The SS Blind Flanges consist of holes around its perimeter, and the gasket which seals the rings is machined into the mating surface. We manufacture ASTM A182 F304 Blind Flange, which comes in many shapes and dimensions according to the client’s particular requirements. The ASME B16.5 Blind Flange follows the industrial standard of quality and safety, and these are available in size NPS ½” to NPS 24. It is frequently produced from forged, cast, or plate material.
The ANSI B16.5 Blind (BLRF) Flange we manufacture is well suited for environments with high-temperature pressure. We also specialize in EN 1092-1 Type 05 Blind Flange production, which is widely used in various industries, including gas, oil, petrochemical, etc. One of the best properties of these blind flanges is that they can be assembled and disassembled quite easily. We are one of the top manufacturers and stockists of Stainless Steel 316 Blind Flange, which has austenitic stainless steel along with chromium, nickel, and molybdenum. We also have a huge ASTM A182 SS BLRF Flange stock- these are all made of high-quality raw material using the latest machinery to give our clients the best-finished products.
