As reported, Shaanxi-Beijing pipeline system is called “Capital Gas Supply Lifeline”. As Beijing-Zhangjiakou pipeline serving Beijing Winter Olympics, Shaanxi-Beijing No.4 natural gas pipeline carries the significant responsibility of guaranteeing the natural gas supply for Beijing Winter Olympics.

In May 2021, National Network Group invited tenders to provide seamless steel pipe for Shaanxi-Beijing No.4 pipeline. Eventually, HYST was awarded part of the tender—thousands of the line pipes for the construction of 3 branch lines and their stations of Shaanxi-Beijing No.4 pipeline.   

HYST has completed the production and shipping of all the line pipes included in the tender awarded on time and with good quality, making sure that Shaanxi-Beijing No.4 pipeline was constructed and put into operation before Beijing Winter Olympics started, thus contributing to the supply of clean energy for Beijing Winter Olympics.
