The welding task of high-pressure pipelines in the nitrogen trifluoride test project team is completed

2020-06-21

Recently, under the guidance and help of the project team, the nitrogen trifluoride experimental project undertaken by the Comprehensive Management Department has been successfully completed through the joint efforts of the maintenance team of the Comprehensive Management Department led by Li Jin. Among them, the high-pressure filling pipeline has a design pressure of 13Mpa. The welded joint radiographic flaw detection was carried out by Shandong Qirui Nondestructive Testing Co., Ltd., and it was 100% qualified at one time, and then passed the 15Mpa hydraulic test, which marked the successful acceptance of the experimental project.
The high-pressure filling section of the nitrogen trifluoride experimental project has a special medium and high filling pressure. It is the pipeline with the highest design pressure used by our company so far, with 73 high-pressure welding ports. Each welding joint was carried out in strict accordance with the operation steps, carefully welded to ensure the welding quality, and successfully completed the welding task.
The nitrogen trifluoride test project team has been committed to the research and development of higher purity nitrogen trifluoride. The completion of the welding project has improved the project equipment and promoted the work process of the nitrogen trifluoride project.
