Computer Aided Design of the Butt Fusion Welding Processes on Polymer Pipes

 

Jointing # 1992 Eindhoven

A computer program for the prediction and optimisation of process parameters for the butt fusion welding of polymer pipes is described. At the core of the program a mathematical model predicts bead size, melt layer thickness,pipe displacement and temperature : time history during each stage of the process for different pipe sizes and environmental conditions. The program includes a database of material properties required for the analysis, and a database of results providing fast access for comparison with empirically derived parameters. Results are presented for three types of polymer pipe material over a range of pipe sizes and environmental conditions.

The erosion of pipe materials in slurry flow streams occurs through a variety of wear processes. As a result, the comparative wear resistance of materials is extremely difficult to predict from a knowledge of basic physical and engineering properties. Design and selection criteria must hence be based on empirical...
