Draft Details

1.1 General

This Standard covers polyamide (PA) pipe, tubing, and fittings for use in gas mains and services, including the gathering, transmission, and distribution of gases that can contain aromatic hydrocarbons.

1.2 Fittings and connections

This Standard covers all types of fittings and connections used in PA piping systems for gas services, 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 NPS outside diameters and “tubing“ refers to pipe having NTS outside diameters.

In this Standard, test requirements for pipe apply to both pipe and tubing.

1.3 Requirements

This Standard specifies the manufacturing and testing requirements necessary to ensure that the PA compound, pipe, and fittings are of a quality acceptable for use in gas distribution systems. This Standard specifies requirements for

a) primary properties of the compound;

b) physical properties of the finished product;

c) on-line monitoring during production;

d) shipping and storage; and

e) 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.
