North China Daniudi Gas Field actively guarantees the safe operation of gathering and transportation pipelines

Sinopec News Network reported recently that the cathodic protection system treatment project of Tayu Pipeline in Daniudi Gas Field was completed, and the cathodic protection potential of 89 test piles across the line returned to normal
.

The Ta-Yu pipeline is the aorta for natural gas transmission in Daniudi gas field.
To ensure the safe operation of the pipeline and slow down the corrosion rate of the soil to the pipeline, the pipeline adopts forced current cathodic protection measures to protect its outer wall
.

This year, the company's scientific research personnel analyzed the potentiostat and anode bed of the cathodic protection system, and found two abnormalities: the reference electrode of the potentiostat and the excessive grounding resistance of the anode bed
.

Through this treatment project, Daniudi Gas Field has mastered the cathodic protection system failure analysis and disposal methods, conducted a comprehensive investigation of the cathodic protection system of the 7 pipelines under the jurisdiction of the gas field, established a cathodic protection system account, and formulated a constant potential Instrument operation and daily maintenance management manuals have laid a solid foundation for the safe operation of gathering pipelines
