Project Update 20.04.2024 – Double Plugging

On April 20, 2024, Xinyu Feihu replaced about 700 meters of the D406*7 aviation kerosene pipeline by performing double plugging under the premise of interrupting the medium in the pipeline at Guangzhou Baiyun Airport. The design pressure of the pipeline was 6.3MPa, the internal pressure of the pipeline during construction was 2.0MPa, and the material of the pipeline was L360.

Project Update 05.04.2024 – Double Plugging

On April 5, 2024, the D323.9*7 medium pressure natural gas pipeline in Nanchang, Jiangxi Province, was continuously transported with pressure double plugging by Xinyu Feihu and about 400 meters of the pipeline section was replaced. The design pressure of the pipeline was 2.5MPa, the operating pressure of the pipeline during construction was 0.8MPa, and the material of the pipeline was L290.

Project Update 29.03.2024 – Double Plugging​

On March 29, 2024, Xinyu Feihu carried out the dn250-SDR11 ultra high flow rate (25 meters/second) PE natural gas pipeline double plugging project in Suichuan, Jiangxi, replacing about 300 meters of pipeline section.During construction, it’s without shutdown. The pipeline design pressure was 0.4MPa, and the pipeline operating pressure during construction was 0.3MPa.

Project Update 27.03.2024 – Valve Replacement

On March 27, 2024, Xinyu Feihu carried out the project of D325*7 aviation kerosene pipeline single plugging to replace a valve with shutdown at Guangzhou Baiyun Airport. The pipeline design pressure was 6.3MPa, and the internal pressure during construction was 1.6MPa. The pipeline material was L360.

Project Update 14.03.2024 – Valve Replacement​

On March 14, 2024, Xinyu Feihu replaced a valve in the horizontal state of DN300 ammonia water pipeline by perform single plugging in Xichang City, Sichuan Province. The design pressure of the pipeline was 2.5MPa, the operating pressure of the pipeline during construction was 0.7MPa, and the material of the pipeline was L290.

Project Update 30.01.2024 – Hot Tapping​

On January 30, 2024, Xinyu Feihu performed hot tapping(the hole is DN100) on the D323.9 natural gas medium pressure pipeline to install a new branch line without shutdown in Zhaoqing, Guangdong Province.

Xinyu Feihu: D159 chilled water pipeline with non-stop transmission was performed two cylinder type single plugging operation

In the science and Technology Research and development center of the head office of the Bank of Beijing, Mapo Town, Shunyi District, Beijing, China Construction Technology Group Co., Ltd. needs to seal the valve of the chilled water supply pipeline with continuous transmission and pressure cylinder in the two water pipe Wells on the east and west sides of the third floor of the A1 building of the research and development center. The company decided to invite a professional construction team for hot tapping and plugging to be responsible for the implementation.
