1.1 This practice describes the procedures for the rehabilitation or reconstruction of pressure pipelines and conduits with 4 to 144 in. (101.6 to 3657.6 mm) diameter or greater constructed of steel, ductile iron, cast iron, asbestos, cement, concrete iron, PVC, CVPC, and HDPE using spray-applied thermosetting polymeric linings that have been certified by the material manufacturer for spray in place pipe (SIPP) lining of pressure pipelines. This rehabilitation/reconstruction process can be used in a variety of pressure applications such as potable water, gas, and petroleum pipelines. 1.2 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This practice applies SIPP to requiring structurally interactive and structurally independent linings. 1.4 This standard does not purport to address all the safety concerns, 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.
Standard is needed as currently there is no ASTM standard for structurally independent SIPP linings. The standard will afford the user a standard for the proper installation methods, quality control, and calculus for determining liner thickness. Municipal, industrial, and governmental agencies are in need of this standard.
