|This Standard applies to underground, thermoplastic pipelines
used in the conveyance of irrigation water to the point of
distribution and may or may not apply to potable water systems.
Polyvinyl chloride (PVC) plastic pipe, standard dimension ratio
- pressure rated (SDR-PR). This Standard applies to underground
thermoplastic PVC (SDR-PR) pipelines 21 to 914 mm (0.5 to 36 in.)
nominal diameter with a pressure rating of 2170 kPa (315 psi) or
NOTE – Nominal pipe size in millimeters is the actual outside
pipe diameter to the nearest millimeter for OD controlled pipe and
the actual inside diameter to the nearest millimeter for ID
Chlorinated poly(vinyl chloride) (CPVC) plastic pipe (SDR-PR).
This Standard applies to underground thermoplastic CPVC (SDR-PR)
pipelines 21 to 394 mm (0.5 to 12 in.) nominal diameter with a
pressure rating of 2170 kPa (315 psi) or less.
Chlorinated poly(vinyl chloride) (CPVC) plastic pipe (SDR-PR),
schedule 40 or 80. This Standard applies to underground
thermoplastic CPVC (schedule 40 or 80) pipelines 21 to 394 mm (0.5
to 12 in.) nominal diameter with pressures ratings determined in
accordance with ASTM F441, schedules 40 and 80.
Polyethylene (PE) plastic pipe, (SDR-PR). This standard applies
to underground thermoplastic PE pipelines 21 to 1600 mm (0.5 to 63
in.) nominal diameter with a pressure rating of 1750 kPa (254 psi)
Purpose. Thermoplastic pipe is manufactured in
several size classifications from different materials of various
grades, types and formulations involving many different
specifications. It is used for applications other than irrigation
where certain requirements often apply to pipe used for a specific
purpose. This Standard pertains to thermoplastic pipe used
underground for irrigation and is intended to:
Provide minimum guidelines for engineers and others in planning,
designing and specifying thermoplastic pipe commonly used for
irrigation. It is not intended as a complete specification nor to
replace the judgment of personnel familiar with site conditions or
other controlling factors.
Consolidate applicable reference information and technical data
in readily available form.
Establish uniform standards for materials used in the
manufacture of thermoplastic irrigation pipe and to promote
uniformity in classifying, pressure rating, testing and marking the
Establish minimum requirements for the design, installation and
testing of pipelines which are necessary for the satisfactory
performance and safe operation of the irrigation system and to
prevent damage to the system.
