South-to-North Gas transmission Cross Yellow River beach Project
DongMing Cross Yellow River beach Project includes South-to-North Gas transmission Yellow River beach HDD Crossing Project:
Pipeline Specification: Φ355.6×7.92mm, LSAW (Longitudinally Submerged Arc Welding)
Crossing Distance: 1857m
And Modification of Cross-Yellow River section of ZhongYuan-Kaifeng gas transmission pipeline:
Pipeline Specification: Ф711×17.84
Design pressure: 8MPa
Crossing Distance: 1829.61m
A series of difficulties was encountered at early stage of the project, such as long crossing distance, steering control, complicated geological conditions; it was solved under proper organization of PM wang yanmin, lai yongbin, zhang chunjing and cooperation of all team members (Jia yongfang, chen yongliang, jia yongzhen, wang weiliang, ji shigui etc). Pull-back of South-to-North Gas transmission Yellow River beach HDD Crossing and Modification of Cross-Yellow River section of ZhongYuan-Kaifeng gas transmission pipeline was completed on March 28 and April 30 respectively.
