Hydrodynamic Isolation

The purpose of a Hydrodynamic Tool is to provide a constant cycle of cooling water to the Isolation Tool during Post Weld Heat Treatment (PWHT) operations, while still maintaining positive pressure between the seals to keep a constant hydrostatic barrier in place.

  • Provides a constant cycle of cooling water
  • Dissipate the heat from welding, Post Weld, or back-out Heat Treatment (PWHT) operation
  • Keep a constant hydrostatic barrier in place

The HDSCIT Tool requires a constant supply of water continuously flowing through the isolation tool to dissipate the heat from welding or Post Weld Heat Treatment (PWHT) operation.
