What is PD CEN/TR 1591-2 about?
PD CEN/TR 1591-2 is the second part of a multi-series of standards which gives details of generic gasket parameters for use in EN 1591-1 during preliminary calculations during which the type of gasket to be used in an application is to be decided. Once the gasket type has been decided the parameters for gaskets of that type from the different potential commercial suppliers should be used in further calculations as within a gasket type there will be differences depending upon the supplier.
Who is PD CEN/TR 1591 for?
PD CEN/TR 1591-2 on gasket parameters is useful for:
- Manufacturers of flanges and their joints
- Manufacturers of gasket
Why should you use PD CEN/TR 1591-2?
A gasket is a mechanical seal that fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.
PD CEN/TR 1591-2 provides the typical gasket parameters for various gasket styles intended to be used in preliminary calculations.
With PD CEN/TR 1591-2 you can obtain measured data for the style and thickness of the gasket intended to be used to ensure that the flanged joint is safe and tight, and also lets you know the relation between the gasket types and the codes used in the tables and gives public sources of reliable data.
Overall, PD CEN/TR 1591-2 helps you in the manufacturing process of gasket circular flange connections in order to provide leak-free flange connection pipes.
What’s changed since the last update?
PD CEN/TR 1591-2:2020 supersedes EN 1591-2:2008.
PD CEN/TR 1591-2:2020 includes some technical changes with respect to EN 1591-2:2008. These include:
- The introduction of the creep parameter ΔeGc
- The introduction of the compressed gasket thickness measured during compression phase eG
- The removal of EG and eG results tables for the gasket codes K04, E02, G02, A02, G01, B01 and F01 showing measurement discrepancies
