Design Guide for Polyethylene Gas Pipes Across Bridges

This project gathered information from these utilities that had experience with plastic pipe on bridges in order to develop design and installation guidelines. These guidelines can also assist utilities in obtaining waivers and will help other utilities when anticipated changes are made in DOT regulations.

Summary:
U.S. Department of Transportation (DOT) regulations currently permit the use of plastic gas pipelines only where they can be buried. Prior research has shown that plastic pipes can be safely and reliably used across bridges to transport natural gas, and that these installations are more economical than steel pipe. Several utilities have obtained waivers and have installed polyethylene (PE) gas pipe on bridges. This project gathered information from these utilities that had experience with plastic pipe on bridges in order to develop design and installation guidelines. These guidelines can also assist utilities in obtaining waivers and will help other utilities when anticipated changes are made in DOT regulations. This guide discusses bridge crossing categories, methods used to install gas pipe on various types of bridges, design loads, other design considerations, and possible problems. Extensive appendixes contain state guidelines for gas pipelines on bridges for five states, waivers granted for plastic gas pipe on bridges in three states, and data on the calculation of temperature-induced axial stress in an above ground PE gas pipe. A companion report, GRI-00/0155, provides brief design considerations for PE gas pipes across bridges.
