Main Objective

The project will advance a broad understanding of cured-in-place pipe (CIPP) liners as they interact with host steel or cast iron pipe. CIPP lined pipe will be removed after years of gas service and tested using a solid foundation of protocols by Cornell University; an independent expert with a long history in testing of infrastructure. Also, a live gas company demonstration of re-conditioning job using CIPP liners will be performed and added to past test and usage information.

Public Abstract

Cured-in-Place Pipe (CIPP) liners have been considered a rehabilitation option and have been shown by earlier studies and experience to be a ‘suitable material' to recondition steel or cast iron pipe. However, more overall industry and government/regulatory acceptance of CIPP lined pipe is necessary for the gas industry to take better advantage of a technology option that would greatly enhance applicable replacement and rehabilitation efforts. The overall objective of the project is to compile and develop information to advance a broad understanding of the potential for using CIPP lined pipe as a safe and practical rehabilitation or reconditioning option in the gas industry. The CIPP lined pipe system is a composite pipe structure that incorporates the strength of the existing pipe material with the impermeability and flexibility of the resin/polyester fabric. Working together with NYSEARCH/NGA members and with independent experts at Cornell University, NYSEARCH will work to collect past information as well as to test with Cornell extracted field-aged CIPP lined pipe to extremes. NYSEARCH and its members will also conduct a demonstration project of the full CIPP planning, installation and post-installation process that can be evaluated by present-day standards and concerns.
