LNG储罐用高锰钢焊接研究现状及展望
Research Status and Prospects of High Manganese Steel Welding for LNG Storage Tank
摘要
Abstract
With the rapid development of the international liquefied natural gas(LNG)industry,the demand for cryogenic materials for and transportation is increasingly urgent.In order to balance the service performance and manufacturing cost of materials,high manganese steel for cryogenic temperature has attracted extensive attention.properties of high manganese steel materials for LNG storage tank,the formation mechanism of hot cracks in the welding process,the burning loss path of alloy elements,the influencing factors of the performance degradation of welded joints in the cryogenic environment were detailed discussed,and the preventive measures in the actual welding application process were proposed.the same time,the application status of common welding process methods for low temperature high manganese steel and its influence law on the performance are introduced,and the development of new welding methods in the application of low temperature high man-ganese steel is discussed,in order to provide a reference basis for the high-quality welding application of LNG storage tank.关键词
