Benefits of using Hot Tapping or Under Pressure Drilling
Save energy – no loss of temperature either heating or cooling
No loss of inhibitors/anti-corrosives/biocides
No loss of water treatment
No loss of pressure or fresh water being introduced into the system
No venting of air from the system, thereby preventing further corrosion

Environmental benefits
All work is carried out using pneumatic machines, which allows quick and cost-effective work – for instance, we can complete work on a 6”/150mm pipe in just 20 minutes, compared to two hours with traditional methods.
Bishop Pipe Freezing can conduct hot tapping on pipework up to 12”/305mm in diameter.
Hot tapping and under pressure drilling are suitable for
Heating systems
Hot and cold water services
District Heating Schemes
Chilled water systems
Condenser water lines
Fire sprinkler systems
Completion of welding & hot tapping of 24 new 100mm (4”) valve connections into 300mm (12”) and 200mm (8”) cooling water headers, without interruption to critical operating services.
