Baoji successfully developed CT100 steel continuous pipe

On November 13, Baosteel Petroleum Steel Pipe Co., Ltd. (referred to as Baoji Steel Pipe) independently developed China's first CT100 steel grade continuous pipe, which was fully inspected by the National Petroleum Pipeline Quality Supervision and Inspection Center, and its technical performance indicators all met the API Spec 5ST standard. Claim.

In recent years, as oil and gas exploration and development continue to develop into deep strata, ultra-high-strength continuous pipe has become a pipe-making enterprise thanks to its advantages in drilling, staged fracturing, and other operations in deep wells, ultra-deep wells, high-pressure wells, and shale gas wells. Research hotspots.

Baoji Steel Pipe relies on the National Petroleum and Natural Gas Pipeline Engineering Technology Research Center. After more than a year of research, it has made several breakthroughs in the development of coils, special welding wire development, heat treatment of deformation and heat treatment of the entire pipe, and successfully trial production in September 2014. China's first CT100 steel pipe, 50.8 mm in diameter, 4.44 mm wall thickness, and 3,500 m in length, broke the monopoly of foreign technology and filled the domestic gap. It is understood that the CT100 steel continuous pipe is the largest continuous pipe with the highest yield strength in China.
