What Is the Maximum Working Pressure for Hot Tapping?

2026-10-20
The maximum working pressure for hot tapping depends on the selected hot tapping machine, fittings, valves, sealing components, and the pipeline's operating conditions. TTCL offers equipment configurations for applications with pressure ratings of up to 10 MPa (100 bar), depending on the model and configuration. Each hot tapping project must be evaluated against the applicable equipment ratings and approved engineering requirements.
