Buried Fiberglass Pipe Response to Field Installation Methods

In 1970 near Yuma, Arizona, a field test installation of 30 inch diameter fiberglass pipe was constructed. Twelve years later the pipeline was remeasured. Measurements of pipe profile, deflection and strain which result from specific installation conditions provide for characterization of buried pipe response. Analysis of the measured data is presented and correlated to construction technique for each installation condition. Specific field parameters which strongly influence buried pipe response and performance are identified. The importance of these parameters on the behavior of buried pipe are discussed and the effectiveness of various installation methods are evaluated.
