Main Research and Development Achievements

2002-2003

 The Company successfully  realized  the domesticalization of X70 Ф1016x17.5mm SAWL pipes  for  the  first X70  long-distance  transportation pipeline of China – the West-to-East Natural Gas Transmission Pipeline, (together with Wuyang Iron & Steel) and provided 150,000t steel pipes for this project, breaking the long-term pattern that China depended on import of large-diameter SAWL pipes.

2004

2004

 The Company undertook and successfully completed the domesticalization of X80 Ф1016×18.4mm SAWL pipes for the first X80 experimental section – Jining Connection Pipeline of China (together with Anshan Iron and Steel), and provided 1,000t steel pipes for the project.

2004

 The Company undertook and successfully completed the domesticalization of SAWL pipes for Panyu-Huizhou Submarine Pipeline (together with Baosteel), and provided 8,500t steel pipes for this project accumulatively.

2006-2007

 The Company successfully developed X100 (together with Nanjing Iron & Steel, Anshan Iron and Steel and Baosteel) and X120 (together with Baosteel) SAWL pipes for the first time at home, starting the research and development of ultra-high-strength pipeline steel and SAWL pipe in China.

2007-2012

2009-2012

 The Company successfully completed the domesticalization of X70 high-strain welded pipes (together with Nanjing Iron & Steel and Xiangtan Iron & Steel), and provided 28,700t X70 high-strain welded pipes for China-Myanmar Pipelines, including 19,461t welded pipes applied to natural gas transmission pipeline, and 9,285t applied to oil transmission pipeline.

2009-2012

 As one of the global six pipe manufacturers, the Company participated in the research and development of welded pipes for ultra-deep submarine pipelines of below 1,500m of Petroleo Brasileiro S.A. (together with Nanjing Iron & Steel and Xiangtan Iron & Steel), and preliminarily passed related examination and evaluation of Petroleo Brasileiro S.A. and international professional institutions.

2010-2011

 The Company undertook and successfully completed the research and development of SAWL pipes for Wuhai-Yinchuan Gas (Coke Gas) Transmission Pipeline Project (together with Nanjing Iron & Steel), and provided 30,000t SAWL pipes for this project accumulatively.

2010-2011

 The Company undertook and successfully completed the domesticalization of X65 Ф762×30.2mm and X70 Ф765.2×31.8mm SAWL pipes for CNOOC South China Sea Deep-Water Natural Gas Pipeline Project (together with Anshan Iron & Steel), and provided 31,800t steel pipes for this project accumulatively.

2010-2012

 The Company undertook and succeeded in trial production of X80 Ф1219×23.7/26.2mm low-temperature and high-strain SAWL pipes for Alaska project (together with Anshan Iron & Steel and Capital Steel).

2012

 The Company  undertook  and  successfully  completed  the  domesticalization  of X80 Ф1219×26.4mm  high-strain welded  pipes  for  the Third West-to-East Natural Gas Transmission Line (together with Shagang Group and Anshan Iron & Steel), completed the 1,000t trial production and passed experts’ appraisal, breaking the situtation of China’s long-term dependence on import of X80 high-strain welded pipes.

2012

 The Company undertook and successfully completed  the  research and development of X80 Ф1219×27mm  (wall  thickness) high-toughness SAWL pipes for Trans-Asia Pipeline (together with Shagang Group), and provided 12,000t steel pipes for this project, taking the wall thickness of steel pipes for X80 trunk lines to a new level.

2013

 The Company completed the small-batch trial production of X90 Ф1219×16.3mm SAWL pipes (together with Jinan Iron & Steel and Xingcheng Special Steel) and  the single-furnace  trial production of X80 Ф1422×25.7/30.8mm SAWL pipes (together with Shagang Group), passing  the evaluation of TGRC.

2013

 The Company succeeded in the trial production of X80 Ф1219×33mm (wall thickness) high-toughness SAWL pipes and X80 Ф1219×37.9 mm bends (together with Shagang Group), accumulating experiences and laying a foundation for mass production, standard optimization and engineering application.

2014

 The Company successfully completed the trial production of 1,000t X80 Ф1219×33mm pipes for the middle section of the Third West-to-East Natural Gas Transmission Pipeline (together with Shagang Group, Shandong iron & Steel and Xingcheng Special Steel).

2015

 The Company successfully completed the trial production of X80 Ф1422×21.4 mm pipes for China-Russia Natural Gas Pipeline (together with Xiangtan Iron & Steel).

2016

 A new round of research and development of extreme-specification steel pipes and high-strain, sour service and submarine steel pipes is in the process.
