Vibration Excitation Force Measurements in a Rotated Triangular Tube Bundle Subjected to Two-Phase Cross Flow
(The American Society of Mechanical Engineers (ASME), 2007)Two-phase cross flow exists in many shell-and-tube heat exchangers. Flow-induced vibration excitation forces can cause tube motion that will result in long-term fretting-wear or fatigue. Detailed ... -
Considerations in the Design and Analysis of an ASME Section VIII, Div. 2 Reactor Support Skirt
(The American Society of Mechanical Engineers (ASME), 2007)This paper describes the considerations employed in the finite element analysis of a relatively “short” support skirt on a hydrocarbon reactor vessel. The analysis is accomplished in accordance ... -
Note on Shear Load-Testing Feedwater Heater Tube Joints
(The American Society of Mechanical Engineers (ASME), 2007)This paper describes some results of shear load testing of welded and hybrid expanded tube–to–tube-sheet joints. The construction consisted of strength welding SA-688-TP 304N tubes to SA350LF-2 ... -
Effects of Simulated Seismic Loading on LBB Assessment of High Energy Piping
(The American Society of Mechanical Engineers (ASME), 2007)The current Leak Before Break (LBB) assessment is based primarily on the monotonic fracture tearing instability. In it the maximum design accident load is compared with the fracture-tearing ... -
Vibration Excitation Forces Due to Two-Phase Flow in Piping Elements
(The American Society of Mechanical Engineers (ASME), 2007)Severe vibrations were observed in a small piping system comprising two elbows and straight sections configured in the form of a U and subjected to air-water internal two-phase flow. An ... -
Destruction of Cryogenic Pressure Vessel and Piping by Shock Wave
