Titel

PED – piping class ECS__B. Pipelines for ISO dimension series, material P235GH, z=1,0

Orientering

This standard provides recommendations on pipe components with ISO dimensions in pressure classes PN10, PN16, PN25, and PN40.
The standard is a merger of the previous standards SSG 7850E, SSG 7851E and SSG 7852E.
The standard follows the values for maximum permissible pressures (Pc) and temperatures (Tc) for each pressure class according to the European Harmonised Flange Standard SS-EN 1092-1:2018, tables G.4-PN10 through G.7-PN40 and the materials listed therein.
This standard for piping class has been verified and approved against the requirements of SS-EN 13480-3:2017, by notified body (AO) 0409 Kiwa Inspecta AB, certificate no. 20-1013779-100. SS-EN 13480 is a standard that meets the requirements of the EU Directive PED 2014/68/EU.
The Pressure Equipment Directive – PED, was adopted by the European Parliament in May 2014. The Swedish Work Environment Authority implemented the EU-Directive in Sweden on 19 July 2016 in accordance with the regulation [AFS 2016:1].
This standard may also be applied to other materials in material group 1.1 according to SIS-CEN ISO/TR 15608:2017 that have equal or higher strength values. If a material with lower strength values is selected, the components can NOT be used according to the standard.
At fluid temperatures higher than 200 °C, hot dip galvanizing is not recommended as the properties of the zinc deteriorate significantly and the surface layer becomes brittle (it crackles).
