TIP TIG, the welding solution for LNG industries

China’s most giant liquid natural gas storage tank with a capacity of 160,000 cubic meters was welded with the TIP TIG technology. This is one of the biggest LNG storage tanks in the world, and it was made using a special 9% nickel steel alloy that allows ultra-low temperatures.

With a 99.18% of successful weld pass rate, the TIP TIG helped the CNOOC to achieve a breakthrough in the field of ultra-low temperature welding.

The TIP TIG welding process was used to weld 9% Ni steel inner tank wall plates efficiently to aid the CNOOC in achieving a cost reduction of a single tank by 1/3.
