May I ask whether stress can be calculated using CII for large-diameter thin-walled pipes?
Thread Content
I have a question: I’m dealing with a pipe with a DN400 diameter, a wall thickness of 3 mm, operating under a pressure of 2 kilograms and at a temperature of 135 degrees. Can I use CII to calculate the stress in this case?
Material engineers can assist with internal pressure calculations, and the calculation of C2 for large-diameter thin-walled tubes will provide inaccurate results.
It is also fine to keep the stress level at a relatively low level
Let’s check the wall thickness first; it seems that considering corrosion allowance and other factors, 3mm is too thin
