  Blind Flanges ( BLRF Flanges )
 
 

Kalikund Steel & Engg Co manufacture Blind Raised Face (BLRF) Flanges. Blind flange without bore i.e. no centre hole but with all the proper bolt holes. Blind Flanges are used to close the piping system or valves or vessel opening. Its also permits easy access to vessels or pipping systems for inspection purposes. It can be supplied with or without hub as per the manufacture options. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types; however, since the maximum stresses in a blind flange are bending stresses at the centre, they can safely be permitted to be higher than in other types of flanges.

Our blind flanges are available with raised or RTJ faces and also with female threads as sometimes clients want with inside NPT/BSP threaded to allow pressure test connection to be fitted. This blind flanges are sometimes custom made or machined to accept a NB sized pipe to whick reduction is being made. This reduction can be a threaded or welded reduction. 

Blind flanges are available in all of our stainless steel from ½” to 36” and beyond, class 150 to 2500. We Keep stock for the same to meet your most demanding schedules and most rigid technical requirements.
