... 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...

... 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...

... with an optimized assembly procedure, which is enabled with advanced numerical modeling. A significantly improved uniform distribution of bolt preloads is achieved by optimizing the makeup torques, which is implemented by using physical test data as input and uniformly distributed preloads as the target function...

... standards 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...

.... The experimentation has been carried out by a purposely developed specimen, consisting of two parts: an instrumented sleeve, with a double array of strain gauges capable of sampling both the axial preload and the underhead torque, and interchangeable underhead washers. The testing apparatus is provided with a device...
