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

 

Papers

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.

The replacement of fossil fuels like natural gas by sustainable gases such as biogas and hydrogen can mitigate global warming. There has been some debate about the impact of sustainable gases on the materials used in the gas grid. An extensive study of the behaviour of PE, PVC, POM and rubber materials was therefore...

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...

To prevent an enormous surge in the replacement costs of the Dutch PVC gas distribution grid a so-called Exit Assessment programme was started in 2004. This programme determines the actual quality of old excavated PVC-U and PVC-Hi pipes using a tensile-impact test at temperatures varying from -25°C to +47,5°C, whereby...

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...
