This practice describes the procedures for the rehabilitation of sewer lines and conduits for existing pipelines 6 to 108 in. in diameter by the insertion of a machine-made field-fabricated spiral wound liner pipe into the existing pipeline using a winding machine which remains stationary in the insertion pit or, alternatively, which travels along the interior of the existing pipeline. These rehabilitation processes can be used in a variety of gravity applications such as sanitary sewers, storm sewers, culverts, and process piping.
When using stationary installation equipment for existing pipelines 6 to 48 in., after insertion, the spiral wound liner pipe is expanded until it presses against the interior surface of the existing pipeline. Alternatively, for existing pipelines 6 to 108 in. in diameter, the spiral wound liner pipe is inserted as a fixed diameter into the existing pipeline and is not expanded, and the annular space between the spiral wound liner pipe and the existing pipe is grouted.
When using the traveling installation equipment for existing pipelines 6 to 108 in. the spiral wound liner pipe is pressed against the interior surface of the existing pipeline. Alternatively, the spiral wound liner pipe is inserted as a fixed diameter into the existing pipeline, and the annular space between the fixed diameter spiral wound liner pipe and the existing pipe is grouted.

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.
Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.
