Casing Design: Collapse Pressure
Casing Design: Collapse Pressure
(OP)
Hi, I am wanting to know which collapse pressure equation will be appropriate for H-40, OD 30", thickness 0.375" D/t= 80" (is this correct?). In the future how do I select an appropriate equation according to D/t?





RE: Casing Design: Collapse Pressure
You will have to rely on experience to let you know the appropriate equations. Most of the collapse equations are based on emperical data, not first principles, so you will need to find the ones that are better taylored for your specific applicaton.
30 inch diameter is more like conductor pipe than casing, so you will probably be "pushing the envelope" using equations developed for casing in this applicaiton.
