Corosion Allowance:

I.T. 3 mm

O.T. 1.6 mm

Operating Pressure 1 kPa (10 mbar.g)

(Vapour Pressure)

Design Pressure 10 kPa (100 mbar.g)

Maximum allowable diferential pressure between the space below and

above the suspended deck: 0.5 kPa (5 mbar ).

5. MATERIAL SELECTION

Materials used in the construction of this tank shall be in accordance with

Section 4 and App. “R” of API Std. 620.

The materials shall comply with the specifications listed in API Std. 620.

The selection of materials is based on the design metal temperature and on

the type of components (primary, secondary, basic).

Primary components include inner tank parts: shell plates, bottom plates,

shell reinforcement, shell manways and nozzles, piping forging and

bolting, roof nozzle in contact with the refrigerated liquid.

Basic and secondary components include outer tank parts: shell, bottom,

roof plates and structural parts above internally insulated suspended deck.

For a refrigerated tank, the materials for primary components shall

comply with the requirements of Tables R-1 and R-2.

All primary components shall be impact tested in accordance with API

620 Std. Sect R.2.1.2 trough R 2.1.4. Impact testing shall be carried

out for each shell plate, bottom plate and for each plate from which

annular plates are cut.
