Dangyang Zhongran Successfully Completes DN300 Pipeline Project, Showcasing Advanced Hot Tapping Expertise
2026-03-27
Dangyang Zhongran City Gas Development Co., Ltd. has announced the successful completion of a complex DN300 pipeline project, which involved four separate barrel-style plugging operations and four corresponding tie-in connections. The project was executed under demanding conditions, with a pipeline design pressure of 1.6 MPa and an operating pressure of 0.8 MPa.
The successful execution of these four distinct hot tapping and plugging operations marks a significant achievement in Dangyang Zhongran's commitment to maintaining a safe and reliable gas network. Performing multiple hot tapping procedures on a live, pressurized pipeline requires exceptional precision, advanced technology, and rigorous safety protocols.
By leveraging its expertise in hot tapping technology, the Dangyang Zhongran team completed the work without interrupting the gas supply to its customers. This "no-stop" approach is a hallmark of modern pipeline maintenance, minimizing social and economic disruption while ensuring the continuous delivery of clean energy.
