On the 6th, Hunan Hualing Xiangtan Iron and Steel Co., Ltd. (“Hualing Xianggang”) located at the bank of the Xiangjiang River was busy with more than 10,000 tons of “polar steel” shipped. This batch of special steel that can still be strong and resistant to impact tearing in the environment of minus 50 ° C will become the "reinforced iron bone" for offshore platforms in the Arctic Circle and human polar energy development.

Xiao Daheng, IPD project manager of Hualing Xianggang's ship and offshore platform, said that the "polar steel" shipped on the 6th will serve the Arctic LNG2 project. This project is the second large-scale LNG project developed in the Arctic Circle after Russia's Novartek's largest Arctic LNG project in the world, the Yamal project.

The harsh natural conditions in the polar regions make the Arctic LNG2 project have very special and strict requirements for the steel used to construct offshore platforms. Luo Deng, Minister of Technology and Quality of Hualing Xiang Steel, said that "Polar Steel" needs to have good low-temperature impact toughness under extreme cold conditions of minus 50 ° C.

Luo Deng and Xiao Daheng told reporters that with the rich experience accumulated in supplying steel for offshore platforms for the Yamal project in recent years, "Hualing Xianggang" won the order of Arctic LNG2 project in the competition. The new "polar steel" developed by them for this purpose is designed with special chemical composition. The purity of molten steel and the precision of rolling control are very high. It has ultra-high strength and resistance to lamellar tearing. S420) standard.

According to the owner's requirements, "Polar Steel" will be selected for re-inspection by 20% of the steel plate. Luo Deng introduced that "Hualing Xiangsteel" strictly controls the production process, and the product inspection pass rate has reached 100% since delivery. "This is the first batch of Chinese steel companies to supply S420 high-grade offshore platform steel. Its application in polar regions will promote the upgrading of global offshore platform steel." Roden said.
