PRESSURE PIPE

WEDNESDAY, JAN. 31

 

 Track IX = PRESSURE PIPE: WHAT WORKS? CASE STUDIES ON REHABILITATION OF PRESSURE PIPE

Presented by the Pressure Pipe Committee of NASSCO

Moderator: Jennifer Steffens, Market Sector Leader, Pure Technologies, US Inc.

 

This track includes several case studies on successful and not-so-successful pressure pipe rehabilitation projects, and provides the contractor, engineer and owner perspectives.

 

8:30 – 9:10 a.m.

CIPP For Large Diameter Pressure Pipes

Speaker: Frank Kendrix, Senior Project Manager, Infrastructure Solutions

 

Rehabilitation of large-diameter pipe poses unique challenges to owners, as there are few proven technologies available within the industry. CIPP, while used in small-diameter applications for over 20 years, has only been available in fully structural large-diameter applications for the past five years. This presentation will review the challenges and successes of rehabilitating 5,700’ of 48-inch diameter PCCP.

 

9:15 – 9:55 a.m.

Navigating Bends In Pressure Pipe Rehab

Speaker: John Moody, Director of Sales, Primus Line Inc.

 

Identifying a suitable rehabilitation method for critical pressure pipelines is challenging, to say the least. When the need arose to rehabilitate a twin 12”-diameter industrial water line under a busy highway with four 45-degree bends, the solution required the least amount of trench work. This presentation will review the challenges and successes met in this installation.

 

10:00 – 10:40 a.m.

Guidelines For Developing Pressure Pipe Rehabilitation Specifications

Speaker: John Schroeder, P.E., BCEE, Vice President, CDM Smith

 

As the demand for trenchless rehabilitation of pressure pipe grows, so does the need to standardize the design and installation methods and specifications. This presentation will provide owners with the knowledge to properly specify these technologies, including structural design, host pipe preparation, installation, and post installation testing and inspections.

 

10:45 – 11:25 a.m.
