On Site activity with plant pressure equipment in line
Hot Tapping is a technique widely used to create new branches from existing pipeline systems.
It consists of welding or more rarely bolting, a fitting on the affected manifold, installing a full bore valve (gate, ball or special) and then drilling a hole with a drill-cutter equipped with a sealing system to prevent the fluid from escaping.
After drilling the hole and recovering the bottom, the valve is closed, the machine is removed, leaving the new unit ready for use (eg insertion of new tools, connections to new systems, drains and vents, etc.).
