Hydrostatic / Hydrodynamic ISOLATION Service

Isolation Benefits:

  • Ability to monitor the seal and ensure safety of hot-work.

  • Triple vapor barrier design; one is positively pressured.

  • Vent upstream activity safely away from hot-work.

  • Vent gauge to monitor upstream activity.

  • Pressure restraining capability in the event of upstream pressurization.


The Isolation Service safely isolates a line for hot-work, guaranteeing safe keeping of property, equipment and personnel.  Installing a plumber's plug or similar device and hoping for the best is never practice.  ISOTECH technicians are ready to install the isolation tool to make your hot-work project safe, allowing your project to be done quickly, at a lower cost and significantly reduced risk when compared to traditional methods.

Application Benefits:

  • Numerous blinds/scaffolds can be eliminated.

  • Extensive steaming and cleaning can be eliminated because lines do not need to be 100% gas free.

  • Tool can be installed under supplied air, however supplied air is not required once isolation is in place.

The patented CARBER Isolation tool provides a triple vapor barrier with the ability to monitor the seal to ensure safety of any hot-work being performed.  First, the tool is placed into the line upstream of where hot-work is to be performed.  Once tool is properly installed and two outer seals are established, the medium is brought to pressure in the annulus between the seals.  Once this pressure is established, the seals are actively monitored by the ISOTECH technician on-site to be certain no harmful or dangerous vapors are passing beyond the isolation tool.  This service guarantees a 100% positive pressure vapor barrier!

The Isolation tool also has a provision for re-routing any upstream vapors safely away from the hot-work area (typically 50 feet).  The upstream activity is also monitored through a gauge to further ensure the safety of hot-work.  Should the assigned Isolation technician detect any change in upstream activity, hot-work is immediately stopped until the situation is resolved.

One of the most dangerous scenarios found in any plant/production facility is poor communication.  Process technicians and maintenance engineers working upstream all too often will begin a task that is potentially dangerous to hot-work being performed downstream.  This is precisely why the Isolation tool is constantly monitored by a trained ISOTECH technician with the authority to stop hot-work and other activity in the area.

Finally, the newest patented safety feature found on the CARBER Isolation tools is engineered for the ability to withstand most full line operating pressures should a mishap occur.

Because it is the absolute safest technology available, the Isolation tool is written into countless hot-work procedures and facility standards, confirming that safety is a high priority in these operating entities.  Not only is the CARBER Isolation tool safer than traditional methods, it decreases cost and downtime.
