Bars > Krybar

 ARBED/ ArcelorMittal Rodange & Schifflange developed the KRYBAR on demand of the LNG industry in order to provide concrete reinforcing steel for safest cryogenic applications.

 Since 1980, KRYBAR has continuously been improved and adapted to the expanding requirements of the growing LNG industry and design companies.

 One of the major concerns is to provide a maximum degree of safety during the whole life cycle of the tanks.

 For each design temperature the adapted KRYBAR:

 For the different design temperatures which can be met in the construction of gas tanks, ARES offers the adapted product:
 LNG tank with a design temperature of -170°C:
KRYBAR -165 & KRYBAR - 620

 ETHYL tank with a design temperature of -105°C:

 LPG tank with a design temperature of -50°C:

KRYBAR is produced in the diameters 12, 16, 20, 25, 28, and 32 mm.

 For qualifying concrete reinforcing steel at cryogenic temperature, following criteria are used:

a) uniform elongation at maximum load on un-notched bars: min 3%
b) uniform elongation at maximum load on notched bars: min 1%
c) NSR >= 1
 NSR= Notch Sensitivity Ratio =

Tensile strength of the notched bars
———————————————————————≥ 1
Lower yield strength of un-notched bars

The Rm/Re value is higher than for standard reinforcing bars which provide further security advantage against hazard loads. (Earthquake, plain crash)

KRYBAR is a product of very high ductility even at low design temperature and has still sufficient ductility even on notched bars. (simulated damage)

KRYBAR fulfills the EN14620 & BS7777 at low temperature and the EN 10080 Grade B500B at ambient temperature.

Since 1980, KRYBAR has been field proven in the construction of more than 200 tanks worldwide for liquid gas what makes the international reference of ArcelorMittal Rodange & Schifflange S.A. for KRYBAR.
