What is Carbon Steel Blind Flange

Carbon steel blind flange is a flange without a hole in the middle and used to seal pipeline openings. Carbon steel blind flange are plays the same function as the head and pipe cap. Moreover, blind flange can also called blind plate which sealing is a detachable sealing device.

The blind flange is basically a flange that does not have a hub or a bored center. Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern.

A blind flange may be used for isolating a pipe, valve, or pressure vessel. There are various types of sealing surfaces, including flat, convex, concave convex, tenon groove, and ring connection surfaces. Material of blind flange are plenty, such as carbon steel blind, alloy steel blind flange, low temperature steel blind flange and stainless steel blind flange.

Specification of ASME B16.5 Forged Steel Flanges

ASME B16.5 standard covers pressure temperature ratings, materials, dimensions, tolerances, marking, testing and methods of designating openings for pipe flanges and flanged fittings. Such as weld neck flanges, slip-on flanges, socket weld flanges, threaded flanges, blind flanges, lap joint flanges and flangolets.

ASME B16.5 Standard

This standard covers pressure temperature ratings, materials, dimensions, tolerances, marking, testing and methods of designating openings for pipe flanges and flanged fittings. Such as weld neck flanges, slip-on flanges, socket weld flanges, threaded flanges, blind flanges, lap joint flanges and flangolets.

Heat Treatment

Heat treatment is not a mandatory requirement except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4” NPS and above Class 300. When heat treatment is required, annealing, normalizing, normalize and temper, normalize and quench and tempering shall be the applied methods.

Application Of Carbon Steel Blind Flange

Carbon steel blind flange could be used when testing pipe pressure or to create an access point in a piping system. And to temporarily seal a piping system while modifying or repairing the line, Moreover to create a long-term seal to terminate a piping system.

Blind flange is bolted, rather than welded in place. This allows easier access as needed for pipe system upkeep, inspection, and allow for future expansion. Blind flange’s use and characteristics are very specific and different from those of other flange just as blind flanges and stainless steel blind flanges.

Carbon steel blind flanges are designed to close and seal off the ends of pipes or pressure vessels. Pairing with a gasket creates a tight seal and gasket fills the space between the flange faces, which prevents liquid or gas leaks.
