Recently, in order to effectively perform the on-site supervision responsibility of the fourth party non-destructive testing and ensure the controllable construction quality of Changchun Shijiazhuang natural gas pipeline project (Changling Shijiazhuang section), entrusted by the national pipeline network company, the product business operation management department of the company headquarters set up a special working group for non-destructive testing to supervise the implementation of non-destructive testing process for the first time. The working group took dual measures of "professional verification technology empowerment, for the construction quality of this countrys important energy channel" pulse escort ".
The feldspar pipeline project is not only the "energy artery" to ensure the stable supply of natural gas in the northern region, but also the key hub of the cross-regional energy distribution network. The working group lasted 10 days, spanning the three provinces (regions) of Jilin, Inner Mongolia, and Hebei, went deep into the core construction area of the 1103-kilometer pipeline, and carried out "full-dimensional verification precision empowerment" technical services for 7 third-party inspection units. In the process of work, the working group not only carries out the whole process verification on the standardization of the inspection process, data authenticity, equipment compliance, etc., but also provides professional guidance for on-site technical problems. After systematic combing, a total of 27 rectification optimization points were found and identified, which not only provided a clear direction for project quality rectification, but also built a standardized template for the companys subsequent quarterly on-site supervision and inspection work.
As a leading national key project in the industry, the construction scale and technical standards of feldspar pipeline project are at the leading level in the industry. Facing the supervision requirements of high-difficulty projects, the working group takes "high-standard supervision, no dead angle coverage, and strong professional empowerment" as the goal. The goal is to prepare ahead of time, form a professional team led by senior inspection experts, and formulate special supervision plans for key links such as pipeline welding, inspection and process execution, ensure that supervision covers the entire NDT process. The rigorous style and professional ability shown by the working group on the spot have been highly praised by the national pipe network company, praising its "accurate and efficient supervision, strong technical support, and building a key line of defense for the quality of the project".
The successful completion of this supervision work not only builds a "security firewall" for the quality of feldspar pipeline projects, but also demonstrates the companys professional credibility in this field. In the future, the company will continue to sum up experience, contribute to the strength of classification societies for more national energy channel quality control, and accumulate valuable practical experience for the companys subsequent supervision of similar projects.
