New Practice for Sectional Repair of Existing Gravity Flow, Non-Pressure Pipelines and Conduits by Pushed or Pulled-In-Place Installation of Cured-In-Place Thermosetting Resin Pipe (CIPP)

1. Scope

This practice describes the procedures for the sectional repair of gravity flow, non-pressure pipelines and conduits 3 to 60-in (75 to 1500 mm) diameter by the installation of a resin-saturated liner which is placed onto or wrapped around an inflatable carrier device, pushed or pulled into an existing pipeline or conduit and expanded against the interior of the host pipe or conduit with air pressure. The resin is cured under ambient conditions, by photoinitiated reaction or with the application of heat. When cured, the finished sectional repair will be tight-fitting across its installed length. This repair process can be used in a variety of gravity flow applications such as sanitary sewers, storm sewers, electrical conduits and ventilation systems.

Keywords

ambient cure; binding material; CIPP; cured-in-place pipe; fiberglass matting; photoinitiated reaction; protective membrane; reinforced composite; release agent; sectional repair; silicate resin

Rationale

Sectional CIPP systems have been utilized extensively to repair or seal gravity flow pipelines worldwide for about 30 years. These technologies are commonly specified by municipalities, design engineers and private owners and installed by licensed contractors and municipalities.

The title and scope are in draft form and are under development within this ASTM Committee.
