Jacketed Tank 1

[Engr ZANIA]

What is the code we use to design double jacketed/skin VERTICAL TANK, specifically for cryogenic storage? As my temp is -103 C and -43C.
I thought API-620, can opt but it does not specify anything about the jacketed tank.

API 620 Annex R is normally used for low-temp storage of liquids (-51°C and above).

API 620 Annex Q is normally used for cryogenic storage of liquids (-198°C and above).

Both Annexes discuss requirements for product temperature materials and atmospheric temperature materials. The type of your tank will determine which category each part of your tank falls into.

As far as the codes go it's basically just a tank within a tank. The inner tank cannot be at a lower level than the outer tank level though otherwise it will collapse.

So you design two tanks, one a bit bigger diameter than the other. That's if you're actually going for double containment and not just something to hold the insulation in and stop it getting wet
