... of windings. To validate those selections, the gaskets must pass a leakage and compression criteria set by ASME. For this paper, we will focus on the compression test as required in B16.20 and using criterion values supplied in section SW-2.2 Construction. Testing of smaller gaskets is a relatively...

..., which brings into focus bolted flange connections among other joints. The most common leakage tests for bolted flange connections use media such as helium (EN13555), methane (ASME B16.20) or nitrogen (DIN 3535), but not hydrogen. There are good reasons for choosing these gases, particularly helium...

... is a discrete-time plant with one input and one output, with the command displacement amplitude of one sine wave as the input and the measured acceleration amplitude as the output. This method was tested on an actual Stewart platform-type hydraulic shaking table. Compensation calculations were performed...

... standards and methodologies that provide a basis for practical testing activities. Other methodologies, such as FEA and hand calculations, are available to evaluate the seal tightness on a theoretical basis during the design stage and predict fugitive emissions values. Test measurement for fugitive...

... are available in the market that offers viable sealing methods, but there is no test method to classify them. This work proposes a soot blower test protocol to evaluate the sealing solutions available. Comparative results for the different seal types are presented. mechanical properties testing...

... stages of crack nucleation, short crack growth and long crack growth. Hence, there is a requirement to undertake testing within the short crack growth regime that would bridge the gap between fatigue nucleation and long crack growth (Paris Law) enabling better prediction of total life measured by fatigue...

... which can adversely impact plant operations and personnel safety. The loss of valve supplier credibility is a concern that rarely occurs in mature economies but seem to be more prevalent in countries where design and testing standards are either relatively new or non-existent. To address this issue...

The washer material and surface treatment change among the different specimen sets. The tightening torque is applied by means...

Hence, there is a requirement to undertake testing within the short crack growth regime that would bridge the gap between fatigue nucleation and long crack growth (Paris Law) enabling better prediction of total life measured by fatigue endurance. A test methodology has been developed by Wood to enable...
