1.1 General
This Standard covers polyethylene (PE) pipe and tubing, and plastic and metal fittings for use in gas mains and services, including gathering, transmission, and distribution of fuel gases containing not more than 1% aromatic hydrocarbons.
1.2 Fittings and connections
This Standard covers all types of fittings and connections used in PE gas pipelines, including
plastic-to-metal transition fittings;
plastic component fittings (e.g., elbows, tees, end caps, and valves); and
clamps and couplings.
Notes:
In this Standard, “pipe” refers to pipe having IPS outside diameters and “tubing” refers to pipe having copper tube size outside diameters.
In this Standard, test requirements for pipe apply to both pipe and tubing.
1.3 Applicability to gas distribution systems
This Standard specifies the manufacturing and testing requirements necessary to ensure that the PE compound, pipe, and fittings are of a quality acceptable for use in gas distribution systems. This Standard specifies requirements for
primary properties of the compound;
physical properties of the finished product;
on-line monitoring during production;
shipping and storage; and
markings.
Note: The user of the pipe, tubing, or fittings should refer to CSA Z662 for design and installation limitations of products covered by this Standard.
