Successful Completion of DN600 Hot Tapping and Single-Head Hot Plugging Operation

A DN600 cylindrical single-head hot plugging project has been successfully completed, demonstrating the reliability and safety of advanced hot tapping and hot plugging technologies under live pipeline conditions.

The pipeline involved in this project has a design pressure of 1.6 MPa, an operating pressure of 0.5 MPa, and a wall thickness of 10 mm. All hot tapping and hot plugging operations were carried out without interrupting normal pipeline operation, ensuring continuous service and minimizing operational impact for the end user.

During the execution phase, precise hot tapping was performed to create a branch opening on the live DN600 pipeline, followed by the installation of a single-head hot plugging system. The hot plugging equipment achieved a reliable and stable seal, effectively isolating the target pipeline section while maintaining full pressure control throughout the operation.

This project once again validates the technical advantages of hot tapping and hot plugging solutions in pipeline maintenance, modification, and emergency isolation. Compared with traditional shutdown methods, hot tapping and hot plugging significantly reduce downtime, enhance operational safety, and improve overall efficiency—especially in high-demand gas, oil, and utility pipeline networks.

The successful completion of this DN600 hot tapping and hot plugging operation reflects strong engineering capability, strict adherence to safety standards, and extensive on-site experience. It further reinforces confidence in hot tapping and hot plugging technologies as preferred solutions for complex pipeline interventions under pressure.
