Mech Seal Surface Temps (ATEX)

[Milkboy]

I have been asked to provide surface temperatures for several mechanical seals currently in operation on site.
Temperatures (est.) during normal operation and surface temps of mech seals which have, say, lost barrier flow/pressure or are dry running.

I have enough information to calculate the Heat Generated by the seals on site and from experience I would say its very unlikely the seals will have surface temp of over 60°C if everything is working correctly.

That i suppose is where Im having trouble.
How can I give a realistic estimate of surface temps when the seal is operating incorrectly ??
(dry running, no cooler, blocked cooler etc etc)

Any thoughts and advice welcomed

TIA

As part of our ATEX testing, we have basically dry run seals to see how much heat they generate to class them for T4, T3 etc.

As the ATEX rules have changed for mechanical seals, we now issue paperwork for seals allowing the user to do their own risk assesment. I would be happy to send these to you if you private mail me or provide me with your e mail address.

That'd be good thanks.

Please send paper work to milkboybeta at googlemail dot com

Igoochy/Milkboy,

Any chance you can copy me on the rules and paperwork issued regarding the ATEX rules discussed in the earlier threads on this subject/thread?

Thanks for the assistance.

Hi,

You might try infrared thermography to complete the T-class inspections for both new equipment and also for followups.

The inspector/thermographer should be HazEx Thermography certified but T-class inspections are an excellent application for this technology.
