China's leading steel manufacturer produces world's strongest pipeline steel
font size    

Shanghai Baosteel, China's leading steel manufacturer, has produced X120, the world's strongest gas transmission pipeline steel, sources with the company said on Tuesday.

Only three other companies in the world -- Nippon Steel, Sumitomo Metals and Germany's Europipe -- have the technology to produce this kind of steel.

The first batch of steel has been sent to pipeline makers for trial production, officials with the company said.

X120 (X is a pipe strength symbol) is the world's strongest gas transmission pipeline steel, and is 50 percent stronger than X80, the steel is mainly used in today's gas transmission pipelines.

X120's resistance to low temperatures and to collapse means that it performs well in cold regions and in deep-water offshore areas, where gas fields are usually found, sources said.

Stronger steel can reduce the amount of steel needed for pipelines without affecting gas transmission safety, and save from 5 to 15 percent of total costs, officials said.

Shanghai Baosteel is a leading Chinese steel producer, and a key supplier for China's west-to-east gas transportation project.
