Material Selection for LNG Storage Tank
(OP)
Hi Experts,
If natural gas is liquefied (methane CH4) at -260F and the transport pressure is 4 psi, should the mdmt be -260F and design pressure be higher than 4 psi?

API 620 will be required as API 650 does not permit refrigerated service. It would be prudent to rate the vessel for enough overpressure to permit proper relief valve operation.

If it's a fairly small tank, it might be just as easy to use ASME.

Weldstan,
Yes I understand the concept of pressure head. Thanks.
JStepehen,
I have no problem hiring an experienced engineer if a job like this is thrown my way but I would like to understand as much as I can before I do.
