Discussion on the whole process supervision

The risk control system of data life cycle management. Combined with the special equipment management system, to realize the whole process of long distance gas transmission pipeline safety regulation, pipeline enterprises should be formed in the long-term management practice the pipeline integrity management as the core based on the particularity in the long-distance pipeline in special equipment system, in the current in each construction stage of long distance gas transmission pipeline inspection and test results of original records are kept by each test unit is responsible for, Such as steel plate sampling and test analysis results, non-destructive testing negatives of pipe factory, formation process of girth welding process, girth welding non-destructive testing negatives, etc. For each construction unit, the preservation and maintenance of data and materials is a huge investment, while the operation unit in the use of these resources, but faced with the embarrassment of "no way to check up". Therefore, it is an important prerequisite for realizing the whole-process supervision of pipeline enterprises to establish a long-term mechanism for sharing these data resources so as to facilitate the risk control service during operation and operation. (2) Quality supervision in the whole process of pipeline construction, pipeline quality mainly depends on the quality of steel pipe manufacturing and on-site welding and construction quality two major links. The steel pipe manufacturing process basically realizes the whole process supervision of each link of manufacturing. In terms of field construction, with the accumulation of long distance pipeline construction experience and the improvement of technical level, the field construction quality of domestic long distance pipeline has made a qualitative leap, but the pipeline construction process is still the link with the most concentrated pipeline risk. In this regard, supervision should be strengthened in two aspects: first, risk analysis should be carried out for each construction process to determine the content and indicators of supervision. If the contact is used in the link of the dead mouth, the stress index of the strong force group of the mouth should be determined, and measures should be made to control the occurrence of the strong force group. The second is to establish effective quality supervision system, the index of the construction process have traceability, construction quality control indicators have verifiability, especially to take cover engineering process supervision link, should focus on establishing effect validation experiments, such as for directional drilling pipe exists in the process of damage, such as scratch, deformation can increase in the volume of a length to be dragged back, The appearance and mechanical properties of the redundant backhaul pipe joints were analyzed to determine the backhaul quality of the directional drill.
