monolithic insulating joints or insulating kits?
(OP)
I am involved in a natural gas 36”OD, API 5L (grade not yet defined) pipeline project in Venezuela.
Regarding Cathodic protection for valve stations, a colleague told me that use of monolithic insulating joints is obsolete; therefore insulating kits (gasket, sleeves and washers) must be used.
My main experience is on process plants, not on cross country pipelines, and I have no previous knowledge of monolithic insulating joints. So, I decided searching through Google in internet, and I found very good and updated information on MIJ.
My question is:
Besides lower initial cost, what other advantages have insulating kits to be preferred for this application?

I've been pleased with the one I was involved with, but that's not really much of a test.
