The Lanchang-Chang Pipe Passes Through the West-to-East Aorta

On March 26th, through the joint efforts of the three pipeline companies to build the employees, the Lan Cheng-chang oil product pipeline project successfully crossed the West-East Gas Pipeline at No. 013 pile and +1631 meters of the Zhengzhou branch line.
In order to ensure the normal operation of the West-East Gas Pipeline, the three company Lan Zhengchang Project Department, which has undertaken the task of cross-cutting construction, actively cooperates with the Yuxi Management Office of the West-East Gas Transmission Company and employs professional technicians of the pipeline system to pass through the West-East Gas Pipeline. The pipeline design and construction program were rigorously reviewed and a Safety Agreement was signed.
First, new oil pipelines must maintain a certain safety distance and corrosion protection requirements from underneath the gas transmission pipeline. Newly constructed pipeline welds must be far away from the crossing point. The second is to accurately verify the burial depth and direction of gas pipelines and optical cables before construction and make good marks. The third is to manually excavate trenches within 3m on both sides of the pipeline. Before excavation, the competent department of West-East Gas Pipeline shall be responsible for supervising and guiding construction on site. After the pipeline is exposed, special personnel will be assigned to provide 24-hour strict care. Fourthly, the 12mm rubber plate is used for wrapping in the crossover section of the two pipelines to avoid damage to the outer coating of the West-East Gas Pipeline when the new pipeline is crossed. At the same time, the insulation of the crossover pipeline is ensured and detailed leak detection is performed. Fifth, when backfilling, push it manually from the side and compact it. Fill the backside of the pipeline and backfill the side ditch. Sixth, it is necessary to establish a sound safety management system and complete safety management information for each process. Seventh, we will do a good job in the restoration of landforms and the centralized treatment of waste recycling after completion.
During the construction, the Pipeline III Company strictly followed the construction plan for the “Transit of the West-East Gas Pipeline” and the “Emergency Response Plan for Passing the West-East Gas Pipeline” approved by the West-East Gas Pipeline Management Office to ensure the smooth progress of the crossing project. The personnel of the Yuxi Management Office of the West-East Gas Transmission Company focused on the construction site to closely monitor the construction and ensure the safety of the construction.
