This specification covers flexible, pre-insulated plastic piping systems commonly used to convey hot and cold fluids, including piping systems that are supplied complete with plastic carrier pipe, thermal insulation, and outer jacket manufactured as an integrated system, and are supplied in a coil or as a straight length. Both bonded and non-bonded insulation types are included. Included are requirements and test methods for material, workmanship, dimensions, and endseal testing. Requirements for markings are also given. The components covered by this specification are intended for use in, but not limited to, residential and commercial, hot- and cold-potable water distribution systems, reclaimed water, fire protection, municipal water service lines, radiant heating and cooling systems, hydronic distribution systems, snow and ice melting systems, geothermal ground loops, district heating, turf conditioning, compressed air distribution and building services pipe, provided that the carrier pipe or tubing covered herein complies with applicable code requirements.
Piping systems may include one or more carrier pipes within a common outer jacket.
The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered part of this standard.
NOTE 1-Pre-insulated pipes covered by this specification are typically installed underground in buried applications.
Units-The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
