Main Presentation Highlights:

Don’t worry attendees, thought the topic may be a bit rusty, the speaker won’t be.  In the ammonia refrigeration industry, the term Mechanical Integrity (MI) refers to the maintenance and inspections routinely performed to keep the ammonia safe.  It is also a specifically named element of OSHA’s Process Safety Management program that consistently falls towards the top of their list as root cause of incidents and citations.  Between the threat of an OSHA fine and the fear of an ammonia release making head line news, MI has become an important topic to industrial refrigeration owners.

So why is it so hard to keep ammonia in the pipes?  Is there something magical about ammonia that causes the systems to rust?  Aren’t there industry standards to standardize MI best practice?

This presentation will discuss research at the UW investigating methods to identify MI hotspots, how to remediate, and efforts to bring a technical and practical basis to the MI decisions made by owners, operators and regulators.  Dan will discuss methods to visually identify problems along with some of the technologies that give us the x-ray vision needed to see problem areas under the insulation. 

In case all you HVAC Guys and Gals are worried this topic will bore you, worry not.  It will be interlaced with plenty of pictures of problems…someone else’s problems…to delight the destructive child in every engineer.  Through it all, you may even learn something about carbon steel piping and insulation that you can carry back to your own facilities.
