The recently concluded 5th annual Connected Plant Conference (CPC COVER STORY Monitoring Ammonia and Other Toxic Gas Hazards Equivalent static analysis can be used when just the ground movements are available, based on ASCE 7-10.× COMMENTARY EDITOR'S PAGE Implementing digital transformation.If not, we can even provide the floor response spectrum too, based on the ground motion at the site location. Response spectrum analysisis used in the assessment of structural integrity, if the loads are given in terms of the floor response spectrum.Transient dynamic analysis yields the response of the piping system, if the dynamic excitations are known in terms of time histories of support movements.We perform Finite Element Analysis for the following occasional loading conditions (earthquake, water hammer, etc.). This is constituted by the dynamic pipe support movements, during a seismic event, and the response to these movements depends on the dynamic characteristics of the considered piping systems and their attachments in relation to the characteristics of the loading. Seismic (Earthquake) and Other Building Induced Loads:.Induced by pipe breaks in pressure vessels, pumps, and valves. Such events result in pressure waves which travel through the piping systems in a complicated manner including reflected waves, etc. These events may be due to valve opening/closure, pump start-up or a pump trip. This loading condition occurs as a result of events that trigger hydraulic transients (like as operational changes). Water Hammer/Steam Hammer Loads (Transient slug analysis) :.This loading condition causes the movement of pipes due to thermal movement of the equipment or pressure vessels and the movement of the pipe supports due to seismic loads.ĭynamic analyses are performed for the following occasional loading conditions: Pressurizers’ surge lines are one of the places where thermal stratification occurs. This initiates an extra bending stress and creates local stresses in the pipe cross section due to a nonlinear circumferential metal temperature distribution. This loading condition occurs in the connecting pipes in a horizontal plane between two reservoirs with fluid at different temperatures with small flow rates. This loading condition is induced by different thermal transients. This loading condition is a dynamic condition but normally analyzed as an equivalent static condition. This loading condition consists of the weight of pipe, medium, insulation and any attachment to the pipelines. Operating pressure or upset condition pressures. We perform static analyses for the following loading conditions: We follow ASME B31 standard in the piping design and engineering for the power and process plants and industrial and commercial facilities under various loading conditions such as the weight, thermal, seismic, wind and other dynamic loads. We follow ASME B31 and section III codes and NRC regulations in the piping design of the power plants. We perform pipe stress analyses for the various loading conditions such as: It represents a complete set of rules for the analysis of the mechanical components too. ASME codes cover the design, analysis, manufacturing and inspection of pressure vessels, piping and supporting structures. CAE Piping performs Pipe Stress Analysis based on ASME codes (American Boiler and Pressure vessel).
