Advice on ATEX glanding.

Mspark

Good evening and thanks for looking.

I've had a look at a brand new piece of equipment that needs to be maintained in the coming months. The threads on Exd glands into threaded housings in zone 2 IIC have been coated with copper ease, I understand a non conductive lubricant can be used on threads but I would expect the copper ease to be conductive. Am I right to be concerned. Thanks

    Was the copper grease applied by the manufacturer / installer?

    What is your thinking behind the need for a non-conductive grease?

    You wouldn't be confusing this with the need for a non-setting grease to be used on Ex d enclosure flanges, where required?

    As you have mentioned that the piece of equipment is certified for gas subdivision IIC, is there any risk of acetylene being present?

    Hi Ross

    Thanks for your reply.

    Copper ease has been applied by the manufacturer.

    A lubricant is used to stop galling to the threads between two stainless steel fittings.

    I recall 60079 having information about grease being non conductive but I may be confused with non-setting. I'm on site and don't have access to all my standards and guidance at the moment.
