The Six Ministries invited the Yunnan Provincial Special Equipment Safety Inspection Institute to the project site for inspection and guidance.

On the afternoon of September 2nd, the pressure pipeline pressure test was conducted on the technological transformation piping and instrumentation project of Yunnan Zhengbang Technology Co., Ltd., which was undertaken by the Sixth Engineering Project Department. The project department invited the Yunnan Provincial Special Equipment Safety Inspection Institute to the project site to supervise and inspect the pressure pipeline.

Accompanied by project management personnel and the owner, representatives from the Special Inspection Institute inspected the pressure pipelines at the project site, including P-P1801 (GC1), P-P1901 (GC1), VA-P0416 (GC1), and VA-P0416 (GC1). They supervised multiple pipelines, including the GC1 pressure pipeline under test pressure of 24 MPa and the GC2 pressure pipeline under 3.95 MPa. Subsequently, they checked the relevant documents. The Yunnan Provincial Special Equipment Safety Inspection Institute made the following requirements for this inspection: First, it is necessary to confirm with the design whether some pipelines contain hazardous media and whether airtightness tests have been conducted; second, it is necessary to confirm whether the safety valves can play a safety protection role; third, the non-destructive testing must correspond to the on-site pressure pipeline welds.

Throughout the process, the owner expressed approval of the project department's serious and responsible work attitude, and the Special Inspection Institute gave full affirmation to the quality of the on-site pressure pipelines.
