Description
New Age International (P) Ltd., Publishers Piping Dynamics by A S Rangwala
Fluids are most conveniently transported through pipelines over long distances. At wellheads in a petroleum field, on offshore oil platforms, in petrochemical refinery or in power generation plant, a network of pipelines carries liquids and gases from one location to another. ASME’s Piping Codes provide useful guidelines for configuring tubing, supports and components. But safeguards from dynamic operating conditions are required to avoid catastrophic failure from various sources:
Pulsating pressure waves in resonance with reciprocating machinery speed.
Elevated operating temperatures causing thermal stresses and creep.
Lack of flexibility in piping loop creating failed joints and supports.
Thermal distortion leading to leakage, unstoppable fire and explosions.
Resistance to fracture from pressure and thermal shocks induced by upset operating conditions.
Cyclical and dynamic vibratory loads leading to premature failure from metal fatigue.
This book provides tools to understand and evaluate dynamic conditions, explore methods to attenuate pulsations in acoustic fluid systems, diminish effects of thermal impact and reduce dynamic response in piping systems. A huge array of tubes, connecting elements and supporting structures in complex systems interact with each other when the network is subjected to elevated pressures and temperatures.
Process parameters and operating speeds are ever increasing for new piping installations, and design and fabrication time schedules reducing as total costs keep decreasing. Use of advanced technologies to meet diverse and oftentimes conflicting demands is imperative to obtain reliability and to forestall failure situations. Safety is of primary concern.
