weep rings at pipe penetrations through conc walls

weep rings at pipe penetrations through conc walls

(OP)
I was wondering if anybody can tell me what the minimum weep ring size that needs to be welded ontop steel pipes to achieve a tight water-seal. I heard a 2" steel ring is all that is required to achieve a water tight penetration. Is this true? For my project, I have pipes ranging from 8" to 60" in size and these will be running through a bunch of liquid tanks. I need to know the minimum size required because space is tight in a bunch of places and welding a flange on the pipe will not work.

Thanks guys!

RE: weep rings at pipe penetrations through conc walls

There are other ways to seal around pipes passing thru concrete wall. Bentonite water stop is one - see this simplified detail

Perhaps a more balanced approach would be to use whatever size weep ring will fit for your application to "lock" the pipe to the concrete AND use bentonite waterstop to do the "sealing".
