1.1 This practice describes the procedures for the rehabilitation of sewer lines and conduits by the insertion of a machine-made field-fabricated spiral wound liner pipe into an existing pipeline. 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. This rehabilitation process can be used in a variety of gravity applications such as sanitary sewers, storm sewers, culverts, and process piping.
