Standard Practice for Design and Installation of Thermoplastic Irrigation Systems with Maximum Working Pressure of 63 psi
|Publication Date:||1 January 1993|
|ICS Code (Irrigation and drainage equipment):||65.060.35|
1.1 This practice covers general and basic procedures related to the design and installation of thermoplastic flexible piping systems, with maximum pressures of 63 psi in nominal size diameters 14 in. (355.6 mm) through 42 in. (1066.8 mm), for underground irrigation systems. Because there is considerable variability in end-use requirements, soil conditions, and thermoplastic piping characteristics, the intent of this practice is to outline general objectives and basics of systems design, proper installation procedures, and to provide pertinent references.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
