Current location：Since the construction of Xi’an urban natural gas pipeline network in 1994, the Company has been the main supplier of natural gas pipeline, and now it has accumulated more than 100,000 tons of supply and is still in continuous supply.
A classic case in recent years is “Xi’an Second Gas Source Project”. In 2017, in order to solve the problem of gas source shortage in winter, Xi’an opened the second line of West-East Gas Pipeline as the second gas source for urban gas supply. The total length of the pipeline is 45km, and the whole line is laid with longitudinal submerged arc welded pipes (Φ 914 × 20.6mm) characterized by large diameter, large wall thickness and high steel grade. The Company joined hands with Shanghai Baosteel for five months to complete the supply task with high quality.
