Polyethylene (PE) Pipe for the Transport of Fluids Under Pressure

PURPOSE

This standard specifies the characteristics and test methods relating to solid-wall high-density polyethylene (HDPE) pipe having a hydrostatic design basis greater than or equal to 11 MPa. 

NOTE — The designer may apply one or the other of the service coefficients in Table 2 for different working pressures.

SCOPE

This standard applies to pipe designated by outside diameters belonging to three dimension ranges: CTS (copper tube size), IPS (iron pipe size) and DIPS (ductile iron pipe size) [see Table 1].

This standard applies to pipe designed for the transport of fluids under pressure, whether or not the fluids are loaded with solid particles. Such pipe is used specifically for raw water, drinking water and wastewater pipelines, for industrial and mining piping and for geothermal needs.

This standard does not apply to pipe intended for the transport and distribution of gas or to pipelines whose working temperature exceeds 60°C.

ATTENTION — Pipe defined in this standard is designed according to nominal pressures established at 23°C (see Table 2). The maximum allowable pressure MAP for a pipe component is in function of the temperature t, as the figure to the right illustrates. It follows that any mention of MAP shall be completed by the mention of the corresponding temperature. The thermal factors to use when calculating working pressure at temperatures exceeding 23°C shall be subject to a recommendation by the manufacturer.

This document was developed to serve as a reference document for conformity assessment activities of specific products.

NOTE — Conformity assessment is defined as the systematic examination of the extent to which a product fulfils specified requirements.
