Traditional butt fusion technology relies upon high power electrical sources such as power grids or site generators to provide the power for facing operations, heating operations, and the required machine movements. Some jobsites, however, pose special challenges, such as remote location and the lack or unreliability of available power. Additionally, individual fusion joint records may be required for completed joints for evidence compliance with industry specifications or other recordkeeping purposes. The following case study examines the unique challenges that come with power challenged jobsites and describes a battery powered approach which enables the installer to apply butt fusion while producing detailed joining records for long term traceability and vastly simplifying jobsite logistics.

When butt fusion welding polyethylene (PE) pipes in the field, it is often specified that the pipes must undergo fusibility testing in all combinations of suppliers, diameters and thicknesses before being fused in production. This is a very onerous and expensive task, but must be carried out to ensure that the PE...

Unplasticized polyamide 12 (PA-U12) is increasingly being used in pipe applications, especially in the gas sector. However, the material behavior in the usual quality tests for pipe welds has not yet been thoroughly investigated. For this reason, two research institutes, worked in cooperation with a manufacturer of...

Our research shows that in a torque rheometer test the greater the fusion degree of PVC-U is, the higher the minimum torque of the torque curve is, and the smaller the difference between the maximum torque and the minimum torque of the torque curve. According to the relationship, the method of evaluating the fusion...

More and more a strong desire is noticeable for Non Destructive Testing (NDT) of welded PEjoints. The objective is to determine the long term performance of plastic piping systems made from PE100. To assess the impact of “mostly known defects“ on the long term performance of a welding, well-defined flaws have to be...

The urgent diversion of a river through a rapidly constructed pipeline was required to avert a power supply crisis to the state of Victoria. In early June 2012, the Morwell River surged and a levee collapsed allowing the river to flow directly into the open cut coal mine which supplies the Yallourn power station. The...
