Dear expats,

I am doing a stress analysis of a carbon steel pipe of material API 5L GR B. The ambient temperature of the model is -3 deg Celsius and the design temperature of the line is 93 deg Celsius. The service of the pipe is crude oil and size is 16”. After doing the analysis the maximum displacement of my pipe is 60 mm. The stress acting on my file is very well within the allowable limit. Please advice me is the displacement is within the permissible limit.
