3” #300 Blind Flange ASME B16.5 Stainless Steel Flange ASTM A182 F304/304L/304H

Product Description:

Blind Flange Definition:

A blind flange looks like a plate with bolts holes around. There is no inner hole on the blind flange comparing to other type flanges, so the blind flange is used to close the end of a vessel or piping system. Blind flange also be used for pressure testing for prevent the liquid or air flow

Connection of Blind Flange:

The blind flange is used together with another flange which could be weld neck flange,slip on flange, thread flange or other type flanges. The other flange should be joint with the pipe or vessel , and bolt connection with the blind flange. The function of a blind flange is like a pipe cap, but it could be assembly easily by the bolts . The blind flange is not connected with any pipe or vessel.

Sealing Face of Blind Flange:

The blind flange could be supplied with flat face (FF), raised face(RF) or ring joint face(RTJ). The RTJ type face blind flange is used for high pressure application, the matched flange also should be RTJ face.

Material of Blind Flange:

Commonly the material of the blind flange should be same with the matched flange for joint. Since the blind flange is not welded with the pipes or vessel , some times the material could be different with the pipe material or the other flange in the joint .

Blind flange:

Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.

From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.

However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
