  EN 1092-1 – PN Flanges for Industrial Valves and Piping

  Posted in: Technical Standards Library, European EN Standards

  EN 1092-1 is a European standard for circular steel flanges used with pipes, valves, fittings and accessories in PN-designated piping systems. It specifies flange types, dimensions, sealing faces, tolerances, bolting, materials, marking and pressure/temperature ratings. For industrial valves, EN 1092-1 is essential for correct mechanical connection between the valve and the pipeline. Matching only DN or PN is not enough. Bolt hole pattern, sealing face, flange type and compatibility with the...

  EN 558 – Face-to-Face and Centre-to-Face Dimensions of Industrial Valves

  Posted in: Technical Standards Library, European EN Standards

  EN 558 specifies the face-to-face and centre-to-face dimensions of metallic industrial valves installed in flanged piping systems. It is an important standard for valve selection, replacement and installation because it helps confirm that the valve has the correct installation length. EN 558 is used for PN and Class designated valves and is especially useful when a valve must be replaced without modifying the existing pipework.

  EN 10204 – Inspection Documents for Industrial Valves and Process Equipment

  Posted in: Technical Standards Library, European EN Standards

  EN 10204 is the European standard that defines the different types of inspection documents supplied with metallic products, industrial valves, steam traps, piping components, pressure vessels and process equipment. The standard specifies how manufacturers document conformity with applicable material specifications, manufacturing standards and project requirements. EN 10204 does not define material properties. Instead, it defines how inspection and testing results are documented and...
