Surveying high-energy piping hangers

Using a proprietary camera system to undertake accurate hot and cold hanger surveys

Challengeshigh pressure piping hangers

Operators of plant containing hanger-supported piping can often experience difficulty in inspecting their hanger assets. Challenges include:
  • gaining access to hard-to-reach hangers
  • identifying topped- or bottomed-out hangers
  • reading data from a distance such as hanger name plates
  • the need to install and then remove expensive scaffolding to enable hanger inspection
  • the difficulties in identifying poorly functioning hangers.


hrl: has developed an imaging device able to capture still and moving pictures of difficult-to-reach objects. The device can be used on a telescopic arm to help overcome inspection challenges by:

  • enabling surveys to be undertaken using a standard method
  • providing an inspection system that is safe to use
  • eliminating the need for scaffolding
  • providing video imaging to give visual records of hanger position in hot and/or cold conditions.


Using its imaging device, hrl: undertakes hanger surveys, under hot and cold conditions that benefit clients by:

  • identifying hangers that are operating outside their travel limits
  • increasing their confidence that their plant's high-energy piping-support system is operating within specification or that out-of-specification hangers are being identified for follow-up action
  • reducing the risks of unplanned outages due to pipe cracking
  • providing greater inspection access to equipment without the need for scaffolding that can be costly and time-consuming to erect, and can restrict plant access while in place
  • increasing inspection operator safety by enabling indicator readings to be from walkways
  • enabling readings to be taken at close range and so improving the accuracy of those readings.



"Going through the process of the energy audit was great for two main reasons. Firstly, it identified where we have information gaps and what we can start measuring to better understand our energy usage. Secondly, it independently identified and qu...
