Standard Practice for Rehabilitation of Existing Pipelines and Conduits by Pulledin- Place Installation of Cured-in-Place Thermosetting Resin Pipe (CIPP)
|Publication Date:||1 February 2017|
|ICS Code (Plastics pipes):||23.040.20|
This practice describes the procedures for the reconstruction of pipelines and conduits (2 to 96 in. (5 to 244 cm) diameter) by the pulled-in-place installation of a resinimpregnated, flexible fabric tube into an existing conduit and secondarily inflated through the inversion of a calibration hose by the use of a hydrostatic head or air pressure (see Fig. 1). The resin is cured by circulating hot water or by the introduction of controlled steam into the tube. When cured, the finished cured-in-place pipe will be continuous and tight fitting. This reconstruction process may be used in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
