Several considerations on products pipeline construction in China

Although China's products pipelines have undergone rapid development and taken shape, there still exist some problems in them, such as unsuitable management system, deficiency in construction and operation experience. The main characteristics of products pipelines in China are summarized as follows, that is, high pressure level, advanced equipments, high-level automation, lack of transported oil types, relatively rough management, and highly centralized operation and management. Several problems in the products pipeline management are pointed out in this paper, such as the inaccuracy in batch interface detection, lack of calibration for test instrument, lack of processing capacity of oil mixture, unsuitable size, complicated technological process, big interface tracking error, and inappropriate water hammer protection. Targeting at the pipeline construction and management, corresponding suggestions are proposed, including popularizing "separate storing and transporting" method, equipping mixing facilities, controlling the scale of new pipelines, developing tracking technology with general interface and accurate management technology research for products pipeline.
