Abstract
The pre commissioning chemical agent addition device for subsea pipelines is mainly used to improve the accuracy of the amount of chemical agents injected into the subsea pipeline during pre commissioning.According to the construction technology requirements,the flow rate of added chemical agents is precisely controlled to effectively ensure the effect of chemical agent addition during the construction process of pipeline cleaning,diameter measurement,pressure testing,drainage,cleaning,etc.The drug pump and construction process were studied,and centralized control was adopted to improve equipment synergy,achieve control system automation,and monitor actual added ingredients in real time.In the implementation of the project,the effect of long-term precise injection of drugs was achieved,with many advantages such as efficient construction,accurate data,automatic control,convenient transportation,safety and reliability.
