Advice on heating pipe

Hi,

Before the winter started I had a painter repaint the heating pipe in the attached photo and replaster and repaint the ceiling.

The plastic cracked and fell off.

A friend told me this was likely due to incorrect choice of plastering.

The painter said that I should install an escutcheon, and I think he must have meant I should use a split escutcheon.

Do you think that's good advice?

If so, where do you think I should get one and what material do you recommend?

The pipe is 7 3/4" in diameter.

I haven't found any escutcheons that size at home depot, on amazon.com or at supplyhouse.com

Thank you

That must be a steam pipe and it looks to have insulation over it.

A split escutcheon or a plastic one would do the job. However I've never seen one that big before. You may have to measure the actual pipe size.

The reason the plaster didn't hold is because the pipe expands and contracts as it's heated. It actually moves thru the ceiling. Plaster doesn't have any give to it. You may have to make the repair with white silicone sealant.

Maybe someone else has an idea.

Thank you.
Yes, it is a steam pipe.
It is not insulated - just painted with rustoleam.
The pipe is 7 3/4" in diameter - measured with a tape measure.

That is one large steam pipe. I'm looking around for ideas.

7 3/4" Diameter? Not circumference? Guessing this is an apartment building? And that pipe feeds to other unit's above? Do you own your unit? The ideal fix would be to just enclose the pipe in a chase with framing and sheetrock so you don't see it at all. Not really that difficult a job, though if you can't DIY, probably pretty expensive in your area.

Apologies, your guess was absolutely right! It is 7 3/4" in circumference. Thank you again

I think I can buy an split escutcheon based on the outside diameter.
Plumbingsupply.com has one with an outside diameter of 2-5/8".

A eustachian is a good solution. You can also make your own with a piece of pine and jigsaw a hole. It can look nice as a little molding.

You can also just caulk the gap with a siliconized latex caulk and repaint.

Many options!

Most plumbing pipe is measured by the inside diameter, so you would have to subtract the wall thickness of the pipe. I bet it's 2" pipe (2-1/2" is an odd size). 2" IPS split escutcheons are readily available.

Just looked at my handy dandy chart:

2 pipe O.D. = 2.375

2.5 pipe O.D = 2.875

so the 2 pipe would have a circumference of 7.46 while the 2.5 pipe would have a circumference of 9.0 .

Some paint on the pipe and you would probably measure higher than 7.5 maybe close enough to 7.75. So it would seem the 2 pipe makes sense as steve says.
