BS EN 14620-1:2006 pdf download.Design and manufacture of sitebuilt, vertical, cylindrical, flat-bottomed steel tanks for the storage of refrigerated, liquefied gases with operating temperatures between 0 C and - 165 C — Part 1: General.
3.19
lodmat
lowest one-day average ambient temperature
NOte Th. average temperature is half the sum of the Inasimum and minimum temperature
3.20
maximum design liquid level
maximum liquid level that will be maintained during operation of the tank used for the static shel thickness determination
3.21
maximum normal operating level
Maximum liquid level that will be maintained durrng normal operation of the tank. Normally the level at which the first h.i level alarm Is set
3.22
membrane
thin metallic primary container of a membrane tank
3.23
membrane tank
containment whereby a membrane (primary container) together with load bearing thermal insulation and a concrete tank are forming jointly an integrated, composite tank structure
3.24
minimum design temperature
assumed temperature of the product specified by the pi.wchaser. for which the tank is designed
NOTE This temperature may be lower than the actual product temperature
3.25
Operating Basis Earthquake (OBE)
maxwnum earthquake event for which no damage is sustained and restart and safe operation can continue
NOTE This event would resuh in no loss to the operabonal integrity and public safety is assured.
3.26
out•r lank
self.suppoting cylindrical secondary container made of steel or concrete
3.27
purchaser
company who gives an order to the contractor for the desl. construction and testing of a tank
3.28
primary liquid container
part of a sine. double. ful containment or membrane tank that contains the liquid during normal operation
3.29
product vapour barrier
pdienc vapour barrier or a liner to prevent escape of product vapours from the tank
3.30
ringbeam
arcular uppost LwIdor the shol of the tank.
