Recent Trends in Installation Standards for Plastic Pipe


ASTM Committees are nearing the end of long projects to revise and upgrade Standard Practices D 2321 and D 3839 for the installation of buried thermoplastic and fiberglass pipe, respectively. These revisions include improved and expanded guidance for selection of soils, control of construction procedures and compaction of backfill. The Appendices to D 2321 provide a commentary on installation issues that are critical to the long term performance of flexible pipe and specific guidance to engineers on important topics to be considered in preparing project specifications. The task group working on D 3839 is considering modifications to the deflection prediction equation that will treat flexible pipe deflection in a broader, more rational way than previous versions. This paper highlights the important revisions being addressed in these standard practices and provides background on their development.
