Control Pipeline Pressure Surges


Book Description

Pipeline pressure surges, those sudden spikes, can wreak havoc. But fear not, engineers have tools to control this beast. One approach is designing the system itself. Using larger diameter pipes allows fluid to flow at a slower pace, reducing pressure buildup. Additionally, strategically placed surge tanks act as buffers, absorbing excess pressure during surges. For existing pipelines, pressure relief valves become the heroes. These fast-acting valves open when pressure exceeds a set limit, diverting excess fluid and preventing pipe damage. They then reseal when pressure normalizes. By implementing these strategies, engineers can ensure pipelines operate smoothly, safeguarding them from damaging pressure surges

Flow Modelling and Control in Pipeline Systems


Book Description

This book introduces novel methods for leak and blockage detection in pipelines. The leak happens as a result of ageing pipelines or extreme pressure forced by operational error or valve rapid variation. Many factors influence blockage formation in pipes like wax deposition that leads to the formation and eventual growth of solid layers and deposition of suspended solid particles in the fluids. In this book, initially, different categories of leak detection are overviewed. Afterwards, the observability and controllability of pipeline systems are analysed. Control variables can be usually presented by pressure and flow rates at the start and end points of the pipe. Different cases are considered based on the selection of control variables to model the system. Several theorems are presented to test the observability and controllability of the system. In this book, the leakage flow in the pipelines is studied numerically to find the relationship between leakage flow and pressure difference. Removing leakage completely is almost impossible; hence, the development of a formal systematic leakage control policy is the most reliable approach to reducing leakage rates.
