Flange leakage formula
Thread Content
What is generally the formula used to calculate flange leakage? Where can I find it? Thank you
Haven’t heard of it! It’s related to things like leaks and the size of the leakage points! It seems like there’s no formula! I too am waiting patiently for an expert to appear, just like the original poster
Is it the NC3658 method or the pressure equivalent method?
ASME B31.3 contains some information on this topic
I too look forward to seeing what the original poster wants to see.
Manual for the Installation Design of Process Piping in Petrochemical Plants, Part 1: Design and Calculation of Pipe Stress Analysis – Restrictions imposed by pipes on the forces acting on flanges, pumps, and equipment
Yes, relevant information is provided in Part 1 of the Manual for the Installation and Design of Process Piping in Petrochemical Plants. Additionally, the explanatory notes to Article 7.3.4 of the revised version of SH/T3059-2012 include calculation formulas, namely the verification formulas for the equivalent method.
It is generally done in accordance with ASME B31.3
