This is just a starting point – we welcome everyone to participate more actively in discussions on this forum. The more people involved, the more lively it becomes. Haichuan becomes even better with you here.

The construction of this gas pipeline with a diameter of 610 millimeters and a length of 3,500 meters set a new world record for pipeline crossings. 　　According to Zhao Shaochun, manager of the Pipeline Bureau’s Crossing Company, the crossing distance is as long as 3,500 meters, and coupled with the fast flow rate of the river, it is not possible to carry out magnetic target correction in its entirety, resulting in extremely high construction risks. During the construction, they employed the world’s most advanced butt-joint crossing technology and ultimately succeeded in crossing the Yangtze River. 　　Headquartered in Langfang, the Pipeline Bureau is a specialized pipeline engineering company under China National Petroleum and Natural Gas Group Corporation. This directional drilling project across the Yangtze River represents another world record set by the company in pipeline crossing operations, following the three consecutive world records it achieved in 2013 during the construction of the Jiangdu–Rudong Phase II pipeline project.
