Pipelines perform an important infrastructure role, transporting water for irrigation as well as everyday drinking water. To accommodate natural terrain, irrigation pipelines tend to have many bends and branches. Current design parameters focus specifically on the stability of pressure-pipe bends by evaluating the equilibrium between the thrust and resistance forces. Researchers Yoko Ohta, Yutaka Sawada, Megumi Kitada, and Toshinori Kawabata wanted to study the performance of ordinary pipe joints and pipe bends using different thrust restraints. In their paper, "Improved Thrust Restraint Design Considering Displacement of Pipe Bend and Joint Separation," in the Journal of Pipeline Systems Engineering and Practice, the authors propose a new design method for buried pipe bends with thrust restraints that incorporates pipe displacement. |
