How to replace a 2" pipe leaking between two fixed t's

2" pipe leaking between two fixed t's on wet return. How can it be replaced?
Easy (well as any 90 year old steam pipe is) to remove but do not see how a coupling can be put in as both sides are pretty solid.

    Not a coupling. Two nipples joined by a union. Or, if there's no flex at all, a flanged and bolted union rather than a standard one.

    If you can post a picture that would help. Be aware if you touch it, it is possible some of the adjacent pipe is bad as well.

    Mega press slip coupling.

    There are perfectly round small holes that seem to have been plugged and were fine until they were subjected to an over fill of the boiler. Very strange. Definitely not corrosion. I have to check again but I do not think there is any play even to get a pair of flanges. Hmm did not consider 2 pair. That would leave enough space to get the ends in. Also means $200 of fittings. Beginning to think copper with slip coupling
    will be the cheapest.
