 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 -165°C:
KRYBAR -165

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

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

KRYBAR is produced in the diameters 12, 14, 16, 20, 25, 28, and 32 mm.

 
 KRYBAR meets the requirements of * BS 4449 and BS 7777 Part3 for flat-bottomed, vertical, cylindrical storage tanks in low temperature conditions at a design temperature.

* BS 7777 is the most often applied standard and the referenced material design for the construction of LNG, LPG and Ethylene tanks. The three main mechanical criteria of BS7777, at design temperature, are:

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)

Since 1980, KRYBAR has been field proven in the construction of more then 100 tanks worldwide for liquid gas what makes the international reference of ArcelorMittal Rodange & Schifflange S.A. for KRYBAR.
