Ultra pure water (UPW) is an important resource in several industry sectors. A project in The Netherlands is presented where a pipeline for the transportation of UPW was recently built using PP pipes with a diameter of 280 mm (SDR 17.6). The project was unique in several ways. While typically UPW piping systems are installed indoors, in this project two ~ 7.0 km long pipelines were built outdoor from a water treatment plant which is generating UPW to an oil field. There the purified water is evaporated and pressed down into the oil well. This lowers the viscosity of the crude oil and consequently boost the oil production from the well.
To ensure the purity of the pipeline special measures were taken during the production as well as for the transport and installation at site. Furthermore the welding at site was performed in a specially designed cleanroom container using non-contact heated tool butt welding (IRwelding) to avoid any contamination of the pipes during the installation process. Further criteria at this job have been the pressure test of the 7 km long pipeline and the start up of the system whereby the target was to reach the designated water quality in a very short time frame.
