Natural gas is liquefied at the extremely low temperature of -164 °C, shrinking its volume by a factor of 600. This makes its storage and transport possible and economically efficient. At these very low temperatures, the utilization of special 9 % nickel steels is necessary in order to guarantee sufficient toughness and resistance to brittle cracking. We supply extra wide plates to this market segment, even with a thickness of 5 mm.
The LPG process is used to produce propane and process gases from natural gas. These gases are liquefied at room temperature at low pressure and are stored in special tanks made of 5 % nickel steels. We supply shell plates and vessel heads from a single source.
Highest quality for the highest degree of safety
The basis of our high-quality nickel plates are high-purity slabs from our own steelmaking plant. The very low carbon content guarantees perfect weldability. Further advantages are found in the product's excellent impact strength and the fracture-mechanical properties (CTOD). The entire plate surface undergoes ultrasonic testing. The residual magnetism is below 50 gauss.
