Technical Improvement on Surge Protection Program of Qinhuangdao-Beijing Oil Pipeline

Original surge protection program in Qinhuangdao-Beijing Oil Pipeline is not applicable for current operating requirements because of the variation in oil throughput, transported medium, varied technical process and updated equipments. Therefore, technical improvement on surge protection program is carried out based on transient flow process control of the pipeline to perfect surge protection program so as to truly realize pressure regulation plus "3-level" protection. Verification results from simulation system show that the new surge protection program can realize transient flow process control of the pipeline.
