Scope

This document specifies the material requirements and inspection report requirements
for buried polyethylene (PE) piping systems for the supply of gaseous fuels; describes
the corresponding test methods.
This document, together with other parts of GB/T 15558, is applicable to buried
polyethylene (PE) piping systems for the supply of gaseous fuels, which have an
operating temperature of -20 °C ~ 40 °C and a maximum operating pressure (MOP) not
exceeding 1.0 MPa.
Note 1: The maximum operating pressure of the pipeline system is related to the operating
temperature and the critical pressure of the material's resistance to rapid crack propagation
(RCP), see Appendix C. The reference operating temperature is 20 °C.
Note 2: The MOP of polyethylene pipes is determined based on the design stress σD, the
influence of RCP performance is considered; the MOP depends on the minimum required
strength (MRS) of the material type, the standard dimension ratio (SDR), the overall service
(design) factor (C ≥ 2), etc.
Note 3: The relevant parties are responsible for appropriately selecting the products specified
in GB/T 15558 (all parts) according to specific application requirements and in combination
with relevant regulations, standards or specifications.
