AOGV – Disruptive Maintenance Technology Enters North America

The patented AOGV mechanical isolation tool is a revolutionary technology.  It’s designed for ease of use, allowing you to isolate a pipe segment while the rest of the facility continues to run smoothly – maintenance without cashflow shutdown is totally achievable!  This week, the AOGV team are in North America showcasing the new technology to plant and facility operators, contractors and service companies.

Whenever process plant equipment or systems are required to be taken out of service for major maintenance, repair, or modification, positive mechanical isolations are provided between them and any potential hazardous energy source.

The AOGV installs an isolation spade, a pipe blind or blanks, on a live flanged connection. It can also close or open a spectacle blind or replace a spacer with a line blind while the system is still pressurized. This field-proven technology reduces downtime, removes the need for drainage, venting, purging, and flushing, and increases maintenance flexibility.

The AOGV creates a zero-energy zone where inspection and maintenance work can be performed safely and efficiently, ensuring no lasting impact on the process plant. Once the operation is complete, the flange pair is returned to its original pipe spec state with a new gasket, bolts, and nuts.

The AOGV is versatile – typical AOGV applications include:

  • Repair and modifications of parts of process facilities
  • Retrospective installation of equipment
  • Installation, repair, or replacement of valves
