Hot Tapping Machines
Hot Tapping Machines to Secure Under-Pressure Drilling and Live Pipeline Connections
High-accuracy Hot Tapping Machines for Gas, Water, and Utility Pipelines
Hot tapping (also live tapping, cold tapping, or under-pressure drilling) is a method of installing a branch connection to an existing pipeline without shutting down the pipeline. It does not require draining of wet systems or purging of gas lines, and it is a safe, efficient, and leak-free installation.
Our Hot Tapping Machines are portable, under-pressure drilling machines powered by either hydraulic or pneumatic drives. These machines allow new connections to be made on active pipelines without interrupting their operation, making them essential for transmission pipelines in industries such as oil and gas, water, sewage, and chemical processing.
Being one of the reliable hot tapping machine manufacturers, PTS not only provides equipment but also acts as a hot tapping subcontractor to its clients. We collaborate with commercial gas and mechanical engineering firms and provide full solutions that entail:
- We have a full range of hot tapping machines for sale and rent
- Assistance in choosing the appropriate equipment to use in your pipeline conditions
- Proven machines and accessories that fit the various project requirements
Our client-centric philosophy means that regardless of whether you are undertaking a utility infrastructure expansion project or conducting emergency tapping work, you can access hot tapping equipment that is efficient, safe, and without any downtime.

Pressure Balancing Hot Tapping Machines
PTS produces pressure-balancing machines that contain a pressure-balancing system, which has compensation cylinders that help in balancing high-pressure pipelines. This kind of system reduces stress on the internal components, therefore extending the life of the tapping machine. These pressure-balanced machines are specialized in high-pressure Hot tapping work. They may be run to a pressure of 2175 psi (150 bar).
