Pressure Balancing Hot Tapping Machines
PTS manufactures hot tapping machines equipped with a pressure balancing system, featuring compensation cylinders that help equalize both pipeline and sea pressure. This system reduces stress on the internal components, thereby extending the lifespan of the tapping machine. These advanced hot tapping machines are specifically designed for high-pressure applications or subsea tapping operations, ensuring safe and efficient performance even under challenging conditions. They are rated for pressures up to 2175 psi (150 bar).

Tribar Hot Tapping Machines
PTS manufactures tribar hot tapping machines, designed to be lightweight and portable, making them ideal for low-pressure utility services. These machines are commonly used for applications such as chilled water pipelines in air conditioning systems, air/nitrogen pipelines in pharmaceutical and food processing plants, and for creating bypasses or making branches in these systems. Thanks to their compact design, these machines are perfect for installation in areas with space constraints, such as malls, hotels and data centers. Their lightweight nature allows them to be installed manually without the need for lifting devices. They can be easily moved to higher floors in high-rise buildings using a lift. PTS’s state-of-the-art compact hot tapping machines are invaluable for repairing or replacing damaged pipelines without requiring a shutdown, ensuring minimal disruption to ongoing operations.
