Title: What is EN 1090-1:2009/A1:2011/A2:2016? A Technical Overview

EN 1090-1:2009+A1:2011+A1:2016 is a widely recognized technical standard that outlines the requirements for circular steel flanges and their joint connections. This standard is developed by the European Committee for Standardization (CEN) and provides specifications for various types of flanges, including those used in pressure vessel applications, plumbing, and industrial piping systems.

EN 1090-1:2009+A1:2011+A1:2016 classifies flanges according to their pressure ratings, providing a range of pressure classes from PN 5 to PN 400, indicating the maximum allowable operating pressure at a given temperature. This allows engineers to select the appropriate flange based on the specific requirements of the application.
