Pipeline stress Analysis Conservative method - 01/31/17 08:09 AM

Hi All,

I am doing the pipeline stress Analysis as per B31.4 CODE by using Caesar II Basic model in which the stress failure in OPERATING CASE is 114 % but if I do the same system using ALI the stress Ratio is 76 %..... This shows that Caesar II Basic model is conservative. Can you suggest whether my point of view is correct? and which method is good to adopt (ALI OR Caesar 11 Basic model)

Best Regards

The ALA procedure is a published standard. The c2 Basic method is based on the two papers published by LC Peng.

(Personally, I would use the ALA method.)
