The new analytical calculation method for gasketed circular flange connections NF EN1591-1 [3], has been issued in Europe in 2001. It is an alternative to the existing TAYLOR FORGE gasketed flange connections calculation rules. This standard, based on tightness criteria, gives a more detailed analytical modelling of the behaviour of the connection. However, the “full face” gaskets, located on each side of the bolt circle, are out of the scope of NF EN1591-1 [3], whereas a method partly based on the TAYLOR FORGE rules is proposed in the NF EN 13445-3 [6] and CODAP® [10]. A proposal for the calculation of “full face” gasketed joints, based on [3] is presented here.
