PED – piping class ESS__A. Pipelines for ISO dimension series, material 1.4307, z = 0,7
This standard provides recommendations on pipe components with ISO-dimensions, pressure classes PN3, PN10, PN16, PN25 and PN40.
The standard is a merger of the previous standards SSG 7840E, SSG 7841E, SSG 7842E, SSG 7843E and SSG 7844E.
PN3 applies to simpler piping systems with simpler pressures and loads, for example degassing. Additional loads are calculated on a case-by-case basis. The dimensioning criterion is max. calculation pressure 3 bar at a temperature of 100 °C. The PN3 standard is only intended for pipelines belonging to Section 8 of [AFS 2016:1] according to PED 2014/68/EU.
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.17-PN10 through G.20-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 8.1 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.
