ASTM F 2019 : 2011 : REDLINE

CONTAINED IN VOL. 08.04, 2018 Defines the procedures for the reconstruction of pipelines and conduits (4 to 60 in. (100 to 1500 mm) diameter) by the pulled-in place installation of a resinimpregnated, flexible fabric tube into an existing conduit followed by inflation with compressed air.

1.1 This practice covers the procedures for the reconstruction of pipelines and conduits (4 to 60 in. (100 to 1500 mm) diameter) by the pulled-in place installation of a resin-impregnated, flexible fabric tube into an existing conduit followed by inflation with compressed air (see Fig. 1). The resin/fabric tube can be cured by either the flow through the fabric tube of mixed air and steam or hot water or by use of ultraviolet light. When cured, the finished cured-in-place pipe will be continuous and tight fitting. This reconstruction process can be used in a variety of gravity flow applications such as sanitary sewers, storm sewers, process piping, electrical conduits, ventilation systems, and pressure applications.

1.2 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.

1.3 This standard does not purport to address all of 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.
