In the cold current of minus 14 degrees Celsius, the first section of the Sino-Russian East Natural Gas Experimental Section (Phase I) successfully completed all pressure test procedures after 24 hours of voltage regulation test at 14:00 on November 9, marking the fourth Company (Crossing the Company) Successful winter pressure test of the largest natural gas pipeline in China.
The pipeline diameter of D1422 mm and design pressure of 12 MPa in the test section of the Sino-Russian Eastern Natural Gas Pipeline Project (Heihe-Changling) is the first time for its design and construction in China. The first stage of pressure test is GXAC2018-GXAC2026, with a total length of 3.56 thousand Meters, since September 17, a great deal of data has been recorded during the pipe cleaning and caliper measurement, and the results of previous studies on caliper diameter measurement and pressure test have been verified and confirmed, and technical support has been provided for the construction of the later trunk line.
Biting in the cold, the company tried to pressure pipeline four companies tent tents, stoves, squatting night shift, remember the data, 24 hours a day to focus on changes in pressure every minute.Low temperature strength test, voltage test one-time Of the successful completion of the four companies not only proved the correctness of previous scientific research results, but also reflects the company's pre-commissioning professional team of technical level.To this end, Pipeline four companies (through the company) officially filled the largest diameter natural gas The technical construction of pipeline construction in winter has become the first enterprise in China to have the professional technical construction capacity.
