USA Industries is a specialized manufacturer of high quality industrial blind flanges. We offer immediate delivery for in-stock products, and we stock a large variety of standard sizes in carbon and stainless steel. Plate blind flanges manufactured in special stainless steel grades, nickel alloy and alloy steel can be custom made by request.
Blind flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel. Blind flanges also allow for easy access to the pipe in case work must be done inside the line. They are oftentimes used for high pressure applications.
USA Industries provide these types of flanges in all material grades, specifications, in sizes that range from 1/2" thru 96", and ASME ratings from 150# to 2500#. Because USA Industries is the manufacturer and distributor of our blind flanges, we're able to fulfill your custom requests while staying within your desired timeframe.
Blind flanges are typically provided with raised face or Ring Type Joint (RTJ) facing. When a raised face is necessary for your blind flange, our standard height is 1/16" for flanges under 400#. For flanges of 400# and up, the standard raised face height is 1/4". Vents are available in the middle, top, or bottom of your flange and with socketweld or NPT vent connections.
USA Industries manufactures blind flanges in all steel material grades, including carbon, stainless steel, nickel alloy and alloy steel. USA Industries also has many different blinds in stock and ready to ship 24/7. Blinds are provided for either Series A (MSS SP44) or Series B (API 605) flanges, meeting ASME B16.47 & B16.48/ANSI B16.5 and B16.2 specifications. All other Blind Specifications A182, A350, B160, etc. can be provided upon request for purchase.
Yes, just let us know if you want the lifting lug on the flat face of the blind flange (typically used when the flange is in a horizontal plane) or on the outer edge (typically used when installing in a vertical plane).
