The Steam Permeameter Cell is a laboratory-scale pressure vessel used to perform high pressure, high temperature testing on well cement slurries. Initial sizing of the concentric, two chamber vessel was based on design by rule concepts in the ASME Boiler and Pressure Vessel Code, Section VIII Division 1. However, based on the complex transient loading expected during the specified testing protocol, additional engineering design and analysis was performed to understand the effects of thermal gradients on the overall strength and fatigue performance of the vessel. The objective of the engineering assessment was to show compliance with design margins in the Code when non-listed materials are utilized in the construction.

Using detailed analytical modeling of transient, thermo-mechanical loading, the assessment demonstrated that the Steam Permeameter Cell pressure vessel was safe to operate based on engineering judgement and best practices in vessel design by analysis. Furthermore, several design modifications were identified to improve functionality and overall performance of the test vessel. The final Steam Permeameter Cell design had sufficient static capacity to contain the maximum allowable working pressure (MAWP) of 3,500 psig at a design temperature of 700°F, and fatigue capacity to withstand the intended test protocol over the desired service life.

PVP2020 - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
