1.1 This practice describes the procedures for the rehabilitation of sewer lines and conduits for existing pipelines 36 to 120 in. in diameter by the insertion of a machine-made field-fabricated spiral wound liner pipe into the existing pipeline using a winding machine that remains stationary in the insertion pit. The rehabilitation process can be used in a variety of gravity applications such as sanitary sewers, storm sewers, culverts, and process piping. 1.1.1 For existing pipelines 36 to 120 in. in diameter, the spiral wound liner pipe is inserted as a fixed diameter into the existing pipeline and the annular space between the spiral wound liner pipe and the existing pipe is grouted. 1.2 The values in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only. 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. 1.3.1 Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.
There is presently no standard covering rehabilitation with this product. Such a standard is required by municipal water authorities and similar to specify properly the products available.
