Material Properties Affecting the Butt Fusion of HDPE Pipe
In 2014, the Electric Power Research Institute (EPRI) published a paper authored by Dr. Bryan Hauger and titled "Material Properties Affecting the Butt Fusion of HDPE Pipe" . To quote from the report - "Significant efforts have been expended on several fronts to develop an understanding of butt fusion, which is the most commonly used method to assemble high-density polyethylene (HDPE) pipe. Variables that can affect the quality of the fusion joint are called essential variables. A fusion procedure specification currently needs to be developed and qualified by each organization, then re-qualified whenever an essential variable changes. This poses a very high burden on plant owners and may not be necessary for limited changes to at least some of the essential variables. Several essential variables for butt fusion must be controlled within acceptable ranges to provide reasonable assurance of strong and durable joints. This report provides detailed consideration of HDPE material properties in order to create a deeper understanding of the scientific principles that explain the fusion process".
