Design and Stress Analysis of a New Quick-Opening Seal Device Connected by D-Shaped Shearing Bolts
(The American Society of Mechanical Engineers (ASME), 2007)Because of large scale and heavy weight, end closures of high pressure vessels are usually hard to assemble and disassemble. In this paper, a new quick-opening seal device connected by D-shaped ... -
Estimation of Master Curve Based RTTO Reference Temperature From CVN Data
(The American Society of Mechanical Engineers (ASME), 2007)The ASME code cases N-629 and N-631 permit the use of a master curve-based index temperature (RTTo≡T0+19.4°C) as an alternative to traditional RTNDT-based methods of positioning the ASME ... -
Simulation of Structural Deformations of Flexible Piping Systems by Acoustic Excitation
(The American Society of Mechanical Engineers (ASME), 2007)Valve actuation and pump fluctuation in piping systems generate propagating sound waves in the fluid path which in turn can lead to undesired excitation of structural components. This vibro-acoustic ... -
Stresses in a Cylinder Subjected to an Internal Shock
(The American Society of Mechanical Engineers (ASME), 2007)Hoop stresses due to a moving shock front in either a gas or liquid filled cylinder can be approximated using vibration theory. The equation of motion can be combined with hoop stress equations ... -
On the Mechanics of Residual Stresses in Girth Welds
(The American Society of Mechanical Engineers (ASME), 2007)In this paper, some of the important controlling parameters governing weld residual stress distributions are presented for girth welds in pipe and vessel components, based on a large number of ... -
Emergency Assessment and Repairs of a Process Tower Subjected to Corrosion Under Insulation
(The American Society of Mechanical Engineers (ASME), 2007)A large process tower in a petroleum refinery was discovered to have severe corrosion under insulation (CUI) in two areas. The areas were confined to the vicinity of external rings, but spanned ... -
Combination of Longitudinal and Transverse Ultrasonic Waves for In Situ Control of the Tightening of Bolts
(The American Society of Mechanical Engineers (ASME), 2007)The feasibility of an absolute ultrasonic measurement of the tightening force in bolts was investigated. For this purpose, we used both longitudinal and transverse ultrasonic waves (bi-wave method) ... -
Limit Load Analysis of Cracked Components Using the Reference Volume Method
(The American Society of Mechanical Engineers (ASME), 2007)Cracks and flaws occur in mechanical components and structures, and can lead to catastrophic failures. Therefore, integrity assessment of components with defects is carried out. This paper describes ... -
Analysis of Recent Fatigue Data Using the Structural Stress Procedure in ASME Div 2 Rewrite
(The American Society of Mechanical Engineers (ASME), 2007)In support of the ASME Div 2 Rewrite, a master S-N curve approach has been developed using a mesh-insensitive structural stress procedure for fatigue evaluation of welded components. The ... -
Burst Strength Analysis of Casing With Geometrical Imperfections
(The American Society of Mechanical Engineers (ASME), 2007)Accurately predicting the burst strength is very important in the casing design for the oil and gas industry. In this paper, finite element analysis is performed for an infinitely long thick ... -
A Nondestructive Strategy for the Distinction of Natural Fatigue and Stress Corrosion Cracks Based on Signals From Eddy Current Testing
