Sealing Fitting

1) is admirable, though not applicable to hazardous area electrical installations in Europe; EEx d equipment there has a tapered gland hole and requires metal-to-metal contact between the enclosure and the EEx d gland, which also has a tapered thread, so-many-turns of which need to be engagement between the enclosure and the gland itself. The reason is that it cools the potential flame path below the temperature needed to ignite a flammable atmoshpere outside the enclosure from an explosion within it.

Other methods of protection from explosion in hazardous areas do not require the prevention of migration of flammable gases through a gland fitting, the protection from explosion being effected by other means.

2) Here's an additional vote for this possibility - maintenance of an adequate Ingress Protection rating. GA

Do you know who Abdu is?

You both sound like the same person.

Dear Lyn,

May be if I see him?

Thanks man

If the client is requesting a seal fitting, then before doing anything else:

1.- Find out the electrical classification of the area the unit will be located.

2.- Next make sure that the cables, cable glands, and other electric or electronic components are suitable for the are classification.

It would seem to me if they are asking for seal fittings the unit will be in a classified area, and if so they want to protect the equipment from electrical hazards.

I would suggest you talk to an engineer from the client to confirm the requirements.

Dear All,

I've submit Engineering query to clarify the requirement of the sealing fittings, however client insist to install due to their Standard Operating Procedure.

Thanks a lot for your support.

Regards
