Today, with the rapid development of science and technology, innovation has become a key driving force to promote social progress. Recently, the company has made a major breakthrough in the field of automatic welding of Marine LNG storage tanks, and obtained the Norwegian Classification Society (DNV) certification. This achievement not only marks the technical strength of Botsing Technology in the field of high-end manufacturing to a new level, but also brings more possibilities for the development of the industry.
What is LNG & 9Ni Steel?
Liquefied natural gas (LNG), the main component is methane, is recognized as the cleanest fossil energy on the earth, is a kind of clean and high-quality energy, with high combustion calorific value, less pollution, good economic benefits, non-toxic, tasteless and volatile and many other advantages. Under the background of global economic recovery and low-carbon energy transition, global demand for natural gas has steadily increased in recent years. According to the International Energy Agency (IEA) "Global Energy sector 2050 net zero emissions roadmap" data, from now to 2050, natural gas consumption will increase significantly, coal consumption will decline, and oil will plateau. Natural gas demand will increase from 3.9 trillion cubic meters in 2020 to 4.6 trillion cubic meters in 2030.
LNG storage conditions are more special, and 9Ni steel because of its high strength, low temperature toughness, good welding performance, is the best toughness material used in the cryogenic environment, is mainly used in the manufacture of liquefied natural gas (LNG) storage tanks and transport ships, the lowest use temperature can reach -196℃.
Automatic welding breakthrough!
9Ni steel welding is a key technical problem in the construction of LNG storage tank, and its technological level directly determines the service life of the storage tank. At present, the most commonly used vertical welding method of LNG storage tank is manual arc welding (SMAW), and there are few automatic welding equipment and applications. With its deep accumulation in the field of welding technology and long-term research and testing of the R&D team, Botsing Technology has successfully developed a new automatic welding technology for 9Ni steel vertical welding.
9Ni steel is extremely sensitive to magnetism, and the process magnetism generated by welding current is easy to appear magnetic bias phenomenon during welding, resulting in poor weld forming and affecting welding quality. Botsing Technology adopts a new trackless all-position unguided crawling welding robot system to achieve efficient and high-quality welding of nine-nickel steel through precise control and optimized welding parameters. This not only greatly improves the welding efficiency, but also significantly improves the welding quality, providing a new solution for the automatic welding of nine nickel steel.
With firm belief and the courage to innovate, we will be able to conquer another peak in the field of science and technology. Botsing Technology has successfully realized the automatic welding of 9Ni steel vertical welding, which is an important breakthrough in the field of high-end welding technology in China. This technology provides technical support for the LNG storage and transportation industry and promotes the development of China's high-end manufacturing industry.
