Seismic analysis of piping systems can protect them from the seismic events. Let us look at the list of curated links that signifies its importance.
In petroleum industries, especially in refineries installations, hundreds of miles of
pipes are installed to transfer row and refined material (fluid and gas) from a point to another
of the plant, connecting all the components involved in the transformation process (tanks,
distillations columns, furnaces, etc..).
An attempt to explain process piping engineering basics in detail to help all the process piping engineering professionals around the world.
Piping seismic analysis and design is a critical aspect in piping system engineering. Read the blog to take a look at the benefits of seismic design of piping system for any plant
Full-Text Paper (PDF): Seismic Design Criteria of Refinery Piping Systems
A significant number of damages in piping systems and components during recent seismic events have been reported in literature which calls for a proper seismic design of these structures. Nevertheless, there exists an inadequacy of proper seismic analysis and design rules for a piping system and its components. Current seismic design Codes are found to be over conservative and some components, e.g., bolted flange joints, do not have guidelines for their seismic design. Along this line, this paper discusses about the main issues on the seismic analysis and design of industrial piping systems and components. Initially, seismic analysis and component design of refinery piping systems are described. A review of current design approaches suggested by European (EN13480:3) and American (ASME B31.3) Codes is performed through a Case Study on a piping system. Some limits of available Codes are identified and a number of critical aspects of the problem e.g., dynamic interaction between pipes and rack, correct definition of the response factor and strain versus stress approach, are illustrated. Finally, seismic performance of bolted flange joints based on the results of experimental investigations carried out by the University of Trento, Italy, will be discussed.
