Pressure-while-running hole-making is a technique that involves boring and connecting branch pipelines or installing blocking devices without stopping the operation or releasing pressure of the pipeline/equipment, with the core principle being to isolate the medium throughout the process to prevent leaks.

Core Principle

Hole drilling on pipes using a boring machine, while isolating the internal medium through a sealing structure.

After drilling, quickly connect the branch pipeline or seal the components, maintaining stable system pressure throughout the process.

Applicable Scenarios

Pipe rerouting and branching connections during expansion, such as for water supply pipelines.

Temporary sealing and pre-treatment before equipment maintenance or replacement, or drilling operations for new monitoring or sampling points.

Continuous operation systems for industries such as chemicals, electricity, and municipal services that cannot be shut down
