Wednesday February 4, 2015 Tom Hayes, with Murphy Pipeline Contractors will present on Pre-Chlorinated Pipe Bursting and Swagelining for Watermain Replacement.
All attendees will recieve 1 PDH!!
Pipebursting
Pipebursting allows for the replacement of deteriorated or undersized pressure and non-pressure pipelines. The method consists of insertion of a new pipe of equal or larger diameter into the existing pipeline. The host pipe is fractured by the bursting head and pushed into the adjacent soil by an expander that is 15% larger than the O.D of the new pipe.
The new pipe is then pulled through the annulus space created by the expander. Pipebursting is suitable for both pressure and non-pressure pipelines and can be used to replace all types of existing pipe materials.
In water distribution piping the Pre-Chlorinated Process eliminates the need for temporary services by completing the pressure test and bacteriological disinfection above grade prior to installation. The technology has been used extensively to replace water mains from 2 inch – 16 inch.
Swagelining™
Swagelining uses HDPE pipe with an O.D slightly larger than the I.D of the pipe to be lined. After the pipe string is butt fused together it is pulled through a single reduction die that temporarily reduces the diameter allowing the HDPE to be pulled through the original pipe. After the pipe is pulled through the host pipe the pulling load is released allowing the HDPE pipe to return to its original diameter fitting tightly against the inside wall of the host pipe. The tight fit liner results in a flow capacity equal to if not greater than the original pipe design.
Swagelining is suitable for rehabilitation for a wide range of pressure pipelines as well as larger diameter gravity pipes. Swagelining can be used to install thin wall liners or fully structural pipes.
