The Materials Applications and Experiences (Process Industries) Technical Community of Interest is a group of people (both AMPP members and nonmembers) who have come together for the purpose of furthering a common cause by sharing wisdom, knowledge, information, and/or data  for exchanging and compiling information on the experience of various metallic materials as related to properties, corrosion resistance, fabrication, weldability, repair techniques, and application in various process environments.

  • 1.  Any Experience with Venture Clad Insulation Jacketing/Weather Proofing?

    Ladies/Gentlemen,

    Being a CUI/CUF prevention champion and long-time combatant of CUI/CIU, and advocate for holistic Fabric Maintenance Programs/Methodology, I am always on the lookout for posts/threads and articles on insulation, external coatings and CUI/CUF prevention.   Spotted this post last week and thought our TCI members might be able to help the person that posted this request.

    "Would any Owners, Users, and contractors who have used 3M VentureClad on flexible and lightweight insulation like Aerogel or Pyrogel applied on Reactors, columns, drums, tanks, and other equipment, care to share their experience?

    I would appreciate hearing the advantages and disadvantages of using this 3M VentureClad jacketing. Does it have the strength to resist tearing as the vessel expands and grows? Can it withstand strong wind gusts?"

    This is a very good question.  I do not have any direct experience with the use of Venture Clad in any industrial insulation application, but the concept does raise a few questions.  When Venture Clad is used with fibrous insulations (fiberglass, mineral wool) on vertical applications, does it get sufficient bond to the surface of the insulation (fibers) to prevent drooping or sagging over time under its own weight?  With insulations like silica aerogel, calcium silicate or perlite, which tend to have rather "dusty" surfaces, how well does the adhesive adhere and again prevent the material from settling or sagging over time?  In heavy industrial settings (refineries, chemical/petrochemical plants, power plants...), a major role of the jacket is to provide physical protection to the underlying insulation.  Does Venture Clad offer sufficient puncture and tear resistance to provide the protection required in these applications?  In high temperature applications (250F+), the jacket system is usually left unsealed so it can breathe (allow any water that does enter the system and evaporate at the hot pipe/equipment surface escape).  Would a sealed system like this create a condition where water and steam are trapped in the system?  Just some food for thought...

    Scott,

    Thank you for your reply and thought-provoking questions.  Maybe these questions are addressed in a 3M product demonstration or webinar.   What I've learned, in general, with new products/technology, is that you get a whole lot smarter about their capabilities and limitations once you've installed them in your facility.   This is where sharing experiences with new products can help.   Maybe someone will post a comment or experience with Venture Clad.   Thank you again.  

    Bill
