LNG ships are called "super-refrigerated vehicles on the sea", and their service environment is at a very low temperature of minus 163 degrees Celsius. This requires that the steel for LNG storage tanks must have low temperature resistance, often using Invar steel or 9Ni steel. At present, a complete series of nickel steels such as 0.5Ni steel, 2.5Ni steel, 3.5Ni steel, 5Ni steel, and 9Ni steel have been formed in the field of low-temperature steel. China has also developed relatively mature 3.5Ni steel and 5Ni steel. And 9Ni steel, and successfully used in the construction of low-temperature transport ships.
Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the normalized A131 grade E hull steel plate raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
Steel normalized A131 grade E hull steel plate exports fell sharply year on year. According to the data of the General Administration of customs, 7.811 million tons of steel were exported from January to February, a year-on-year decrease of 27.0%; 2.041 million tons of imported steel, a year-on-year increase of 2.1%. Steel prices continue to fall. According to the monitoring of China Iron and Steel Industry Association, China's steel normalized A131 grade E hull steel plate composite price index at the end of January was 105.48 points, down 0.58% month on month; at the end of February, the index continued to decline to 100.39 points, down 4.83% month on month.
Management information and high efficiency. Because of the rapid flow of normalized A131 grade E hull steel plate goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
