DIN EN 1092-1

Flanges and their joints – Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 1: Steel flanges; German version EN 1092-1:2007
This European standard specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 400 and nominal sizes from DN 10 to DN 4000. This standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange face surface finish, marking, materials, pressure / temperature ratings and flange masses.

DIN EN 1092-2

Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 2: Cast iron flanges
The document specifies requirements for circular flanges made from ductile, grey and malleable cast iron for DN 10 to DN 4000 and PN 2,5 to PN 63. It also specifies the types of flanges and their facings, dimensions and tolerances, bolt sizes, surface finish of jointing faces, marking, testing, quality assurance and materials together with associated pressure/temperature (p/T) ratings.

DIN EN 1092-3

Flanges and their joints – Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 3: Copper alloy flanges
This document specifies requirements for circular copper alloy flanges in PN designations from PN 6 to PN 40 and nominal sizes from DN 10 to DN 1800.

DIN EN 1092-4

Flanges and their joints – Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 4: Aluminium alloy flanges
This standard specifies requirements for PN designated circular flanges for pipes, Valves, fittings and accessories made from aluminium alloy in the range of DN 15 to DN 600 and PN 10 to PN 63. This standard specifies the types of flanges and their facings, dimensions and tolerances, bolt sizes, surface finish of faces, marking and materials together with associated P/T ratings. The flanges are intended to be used for pipework as well as for pressure vessels.
