In 1958, China’s first welded pipe production line was established in Baoji; in 1959, China’s first spiral single-sided submerged arc welded pipe was produced there. In 1960, Baoji Steel Pipe succeeded in producing China’s first batch of welding flux. At the same time, Baoji Steel Pipe has actively assisted in the development of various pipe manufacturing enterprises in China, including those in Shashi and Qingxian. In 2009, it built the world’s third continuous coiled tubing production line; since then, Baoji Steel Pipe has seen its output value exceed 10 billion yuan for four consecutive years. Baoji has become one of China’s most important bases for oil equipment.
