Standard Practice for Rehabilitation of Existing Pipelines and Conduits by the Pulled in Place Installation of Glass Reinforced Plastic Cured-in-Place (GRP-CIPP) Using the UV-Light Curing Method

Significance and Use

4.1 This practice is for use by designers and specifiers, regulatory agencies, owners and inspection organizations who are involved in the rehabilitation of conduits through the use of a resin-impregnated glass fiber tube, pulled in place through an existing pipe or conduit, subsequently inflated and then cured by a designed exposure to UV-light. As for any standard practice, modifications may be required for specific job conditions.


1.1 This practice covers the procedures for the reconstruction of pipelines and conduits (4 to 72 in. (100 to 1830 mm) diameter) by the pulled-in place installation of a resin-impregnated, glass fiber tube into an existing pipe or conduit followed by its inflation with compressed air pressure (see Fig. 1) to expand it firmly against the wall surface of the host structure. The photo-initiated resin system in the tube is then cured by exposure to ultraviolet (UV) light. When cured, the finished cured-in-place pipe will be a continuous and tight fitting pipe within a pipe. This type of reconstruction process can be used in a variety of gravity flow applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems.
