Pipe repair in service
(OP)
I need recommedations on repairing small pinhole leaks in large (30" to 60" dia.) piping. Piping is transporting air (8 psig) for a sewage treatment plant aeration system. Piping system cannot be opened for repair, but can be shut down for 1-3 hrs. Piping is steel with Dresser couplings. Thanks.

Here a just a few of the many repair systems that will do your job. I didn't run down any specifics on any of the products. I've used the Dura Power Product and also one called Sealtight from Team Industries.

You might want to look at Denso type products if external corrosion is the problem.

Now that I know some methods, I can write up a scope of work for it.
