Under pressure drilling is the technique used to form new branch connections within pipework made from materials where welding is not possible, including cast iron, ductile iron, copper, plastic and asbestos cement. Using a mechanical clamp or branch tee, new connections can be drilled directly into the live pipe without interrupting flow, pressure or temperature.
The pipe material cannot be welded
A new connection is needed on a live system
Draining down or depressurising is not an option
Speed and minimal disruption are priorities
No system shutdown required
Full flow, pressure and temperature maintained throughout
Fast and cost-effective using pneumatic equipment
Can be used alongside pipe freezing for a complete live-system solution
