305/2011/EU Construction Products Regulation (CPR) | Carpenter & Paterson Ltd

Pipe Hangers & Supports as defined by EN 13480-3 section 13 & associated appendices are intended solely for the purpose of supporting & distributing the weight & forces generated by the piping into the primary structure. They also allow for the displacement of the piping during plant operation. The connection point to the steel structure can be by direct bolted or welded attachment or by the placement of secondary steel members to provide a convenient connection point.

All attachments to the primary structure are either pre-fabricated by the structure fabricator or else made at site during the installation of the pipe supporting equipment.

The loads & forces imposed on the primary structure by the pipe hangers & supports are known to & considered by the primary structure designer.

Pipe Hangers & supports are therefore classified as a ‘second-fit’ to the primary structure & as such do not provide or enhance the structural integrity of the primary structure. They are designed in accordance with the requirements of BS EN 13480-3 which is harmonised with the “Pressure Equipment Directive” (“PED” 97/23/EC). CE marking under the PED is limited to parts that are welded to the pressure containment part.

Because of this, Pipe Hangers, Supports & associated secondary structural members do not fall under the requirements of either the CPR or EN 1090 when supplied by the pipe hanger manufacturer.
