What is PD CEN/TS 14807 – GRP-UP pipe structural analysis about?
Buried piping systems need to remain durable as they withstand constant pressure over time. PD CEN/TS 14807 is a Technical Specification that discusses plastics piping systems.
PD CEN/TS 14807 is a guidance document for use with a structural analysis procedure for below-ground installations. PD CEN/TS 14807 discusses limits applicable to glass-reinforced thermosetting plastics (GRP) pipes based on unsaturated polyester resin (UP), used for the conveyance of liquids under pressure or gravity conditions.
Products complying with the applicable GRP product standards EN 1796 or EN 14364 , which are not subject to internal pressure, are suitable as long as the analysis shows that the long-term deflection of the installed pipes is limited to 6 %, which is the basic assumption of the GRP pipe product standards.
Products complying with the applicable system standards ( EN 1796 or EN 14364 ), which are subject to internal pressure, are suitable as long as the analysis shows that the initial deflection of the installed pipes does not exceed 3 %.
Note: The approach followed when preparing a general structural analysis procedure does not depend on the nominal size(s) of the pipe(s).
Note: PD CEN/TS 14807 does not specify a particular structural analysis procedure but gives guidance o...
