Ultrasonic Inspection of Butt-Fused PE-Joints [PE]


Plastic Pipes Conference Association # 1998 Gothenburg

Horst, Weyn, Hermkens

For a long time the energy distribution companies in the Netherlands have expressed their need for ways of effectively assessing the quality of field-installed PE-pipe systems to prove integrity and reduce maintenance and repair costs. This becomes especially important with the increased use of these PE-systems for higher pressures. (In these higher pressure systems, xrays inspections are done as quality control on the steel pipe welds.)

In order to address this need, some preliminary tests with ultrasonic inspections on buttfused joints were done at GASTEC using a commercial US testing device, after which it was decided to start a demonstration project for this technique. This demonstration project is funded by EnergieNed, the Dutch branche organisation for the energy distribution companies.

More than 20,000 km of rigid PVC (or PVC-U) pipes are currently in use for the distribution of natural gas in the Netherlands. In this decade, the majority of these pipes will reach their initially specified lifespan of 50 years. In the light of a possible replacement surge, it is increasingly important to identify...

To investigate the suitability of PE pipes for the transport of hydrogen on a specific industrial site, three topics were investigated. These topics are: the chemical resistance of PE to hydrogen, the permeation rate of hydrogen through PE and the electrofusion of PE pipes exposed to hydrogen. It can be concluded that...

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...

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...

One of the options for a low-pressure gas distribution system is the use of ductile PVC pipes and joints. The long-term performance of ductile PVC pipes has been reported in a number of previous studies. In this paper the long-term performance of the socket joints, in which elastomeric (NBR) sealing rings are used, is...
