This precise process requires our experienced engineers to drill a hole in a piping system under pressure, without draining or spilling the products inside.

Safe, fast tie-ins, repairs, modifications and bypass of faulty or damaged systems all under full operating conditions provides exceptional value and efficiency.


  • On-line integration of tie-ins or bypass lines without production loss
  • Installation of thermowells with minimum disruption
  • Avoid expensive emergency shutdowns
  • Sustain manufacturing efficiency

Installation of thermowells under operating pressure

Hydratight’s technique of On-Line Thermowell installation is approved by the TUV, offering assurance of safe and efficient performance.

The connection of resistance thermometers or thermocouples to existing pipelines under pressure requires qualified engineers and special tapping equipment.

Thermowell installation offers precise, robust and permanent temperature measurement of process media where the media may be corrosive, abrasive or at high pressures.


  • Installation of Thermowell at operating pressure
  • Minimum disruption to process/production
  • Ideal for temperature measurement of media where the abrasive or corrosive nature of the media can limit sensor life
