Significance and Use
This practice is for use by designers, and specifies regulatory agencies, owners, and inspection organizations involved in the rehabilitation of non-pressure sewers and conduits. Modifications may be required, depending on specific job conditions, to establish a project specification. The manufacturer of the product should be consulted for design and installation information. Industrial waste disposal lines should be installed only with the specific approval of the cognizant code authority, since chemicals not commonly found in drains and sewers and temperatures in excess of 140 °F (60 °C) may be encountered.
1.1 This practice covers the procedures for the rehabilitation of sewer lines and conduits 4 in. (102 mm) to 18 in. (457 mm) in diameter by the insertion of a folded/formed PVC pipe that is heated, pressurized, and expanded to conform to the wall of the original conduit forming a new structural pipe-within-a-pipe. This rehabilitation process can be used in a variety of gravity applications such as sanitary sewers, storm sewers, and process piping.
1.2 This practice is to be used with the material specified in Section 6 of Specification F1871.
1.3 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.
1.4 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.
1.5 There is no similar or equivalent ISO Standard.
