..., operators and regulators could benefit greatly from a more accurate comparison and estimate of expected flange tightness level, based on design calculations only. This paper will propose a new methodology for sealing effectiveness estimation of bolted connections based on leak rate calculations...

... manufacturers. In order to clarify the validity of the testing procedure, measurements of leak rates of compressed fiber sheet gaskets were carried out and also experiments to check a detectable leak rate by the soapy bubble test were carried out separately. It has shown that the fundamental sealing behavior...
