Pipe Thrust Restraint Considerations: What You Don't Find in a Textbook

The design of thrust restraint for piping systems, especially of large diameter (greater than 24-inch diameter) gasketed push-on joint piping systems, can become complicated as the forces involved in larger diameters reduce the restraint options available to a designer. This is due to larger thrust forces amplifying the pipeline stresses, movements and corresponding soil reactions. Most thrust restraint publications do not address non-standard environments that commonly occur in design. Some of the scenarios that a designer might encounter that require special consideration are fixed leg-flexible leg alignments, pipe telescoping, in-line valves, and limited joint deflection of restrained joints. The purpose of this paper is to address thrust restraint scenarios which require non-standard design considerations, to present potential solutions for such, and to present various phenomena encountered in large diameter pressure systems operating at 100 psi or more, which is typical of most municipal water and wastewater systems. This paper is not intended to address welded/fused-type joint systems, but to address the unrestrained push-joint and restrained-joint type piping systems.
