Using Reinforced Thermoplastic Pipe (RTP) In Natural Gas Distribution Applications



Plastic Pipes Conference Association # 2010 Vancouver

Nathan Lesage, Blaine Weller

Reinforced Thermoplastic Pipe (RTP) combines high performing materials with high strength reinforcements in a unique construction to create a spoolable high pressure pipeline system. This construction is well suited to a variety of applications. The primary use of RTP has been in the upstream oil and gas industry for a range of applications covering oil gathering, gas gathering, water injection and water disposal. RTP has also been installed in eleven gas distribution applications in Canada. This paper is co-authored by the pipeline end user and the RTP manufacturer. It presents an overview of RTP and the experience of the use of RTP in a gas distribution application by AltaGas Utilities Inc. The application is approximately 6.6 km (4.1 miles) in length and has a normal operating pressure of approximately 3.5 MPa (500 psi). It has been in operation since 2007. The advantages and disadvantages of using RTP in this application are discussed taking into account project economics, technical considerations, installation, operation and reliability.

This paper describes falling-weight tests as a first step towards determining the effect of residual stresses on the fracture behaviour of old PVC-U gas pipes at impact. Results showed that the level of surrounding pipe support, the quality of the material and the diameter of the striker had a major effect on the...

More than 75,000 km of PVC pipes are currently in use for the distribution of natural gas in The Netherlands, which make up over 60% of the distribution grid. To gain insight in the factors that influence the quality of those pipes a so called Exit Assessment programme was started in 2004. Part of this programme...
