pipeline for transportation of supercritical co2

(OP)
Hi Guys, I'm new to this forum.

I hope I have posted this in the correct forum.

I have been asked if the API 5L grade B Plus material would be a suitable material to reduce the likelihood of fracture propagation.

I have a hunch as how to approach this problem, but seeing as I am unsure, I was wondering how others might tackle this problem.

Thanks in anticipation,

Frank

RE: pipeline for transportation of supercritical co2

What temperature in service and if depressurised ? It looks to me that you should at least be in A333 gr 6 or preferably stainless, due to low temps.

RE: pipeline for transportation of supercritical co2

High pressures yes, but not necessarily low temperatures are necessary.
  
Crack propagating resistance if not stiffener rings, if not both is a favorable quality.

There's pleanty of internet info available.  Just search for "crack propagation CO2 pipelines"
