BS EN 1092 is a series of European standards on flanges that specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 400 and nominal sizes from DN 10 to DN 4000.
BS EN 1092‑1 is the first part of the BS EN 1092 series of documents that specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange jointing face surface finish, marking, materials, pressure/ temperature ratings and approximate flange masses.
BS EN 1092‑1 on steel flanges is applicable for:
The flanged joint design means that pipes are secured by external screws, providing additional joint support for the transportation of substances at high pressure.
BS EN 1092‑1 navigates you through the standard designation of flanges and types of flange collars.
BS EN 1092‑1 provides the general requirements and methods to manufacture flanges and collars fulfilling the essential safety requirements of pressure equipment. Determination of p/T ratings for flanges is given in BS EN 1092‑1.
Dimensions of flanges and collars, hubs of the flange, threaded flanges, bolt holes, lapped joints and collar types can be determined with BS EN 1092‑1.
BS EN 1092‑1 specifies the general marking and hard stampings requirements on all flanges, lapped ends and collars, BS EN 1092‑1 provides inspection and testing methods of fusion-welded joints and bent and electric welded flanges or collars from formed bars as well as of close die flanges.
Overall, BS EN 1092‑1 assist you in designing steel flanges to be used in building construction that can be used in the piping connection, valves, and other equipment providing an easy point of access for cleaning, inspection, modification and repairs.
BS EN 1092‑1:2018 supersedes BS EN 1092‑1:2007+A1:2013. BS EN 1092‑1:2018 includes some technical changes with respect to BS EN 1092‑1:2007+A1:2013. These include:
