Wind Girt Pipe connection to Pipe Sleeve
Wind Girt Pipe connection to Pipe Sleeve
(OP)
Per a detail on a project I am working on it we have been instructed to slide a 10" Pipe over an 8" sleeve which is welded to an embed plate in a concrete wall. A curtainwall will be attached to the 10" pipe which will act as a wind girt. The rest of the pipe sits in an embed plate which contains a rolled plate with another 1/8" Koralath Pad on it and cantilevers over the embed plate. So in essence one side of the rolled wind girt pipe slides over the 8" sleeve and is free to move and the other side of the pipe is supported by an embed plate which houses a half sleeve to conform around the pipe.
The note on the detail says to wrap 8" pipe sleeve with an 1/8" Koralath Pad and fill space with pre-compressed expandable fill material.
I have talked to EOR and he says this is to create rigidity and allow for the steel pipe to slide along the sleeve connection if necessary. I was also told the pre-compressed expandable fill material could be anything.
I am having trouble figuring out what type of material to select for my Koralath Pad. I was leaning towards Teflon with a steel backing plate to connect to the pipe sleeve. I am not familiar with expandable fill material and want to make the correction selection so the fill material will also be able to slide against the teflon.
Has anyone had experience with this?

If going for something expansive check the induced stresses.

There is a wall within 1" on the both sides of the pipe. If we weld the pipe sleeve to the embed plate in the wall we will be unable to slide the wind girt pipe over the sleeve with the given clearances.
We will have to drop the pipe into place with the sleeve inside it, and once it is in position weld the sleeve to the embed plate in the wall.

Maybe even plastic mortars (as those used for tiles in bathrooms) can work for you. This would give you some degree of workability to shape and strength; you can reinforce it, grind it if necessary and complement to specs with some strong adhesive of weak expansion when placing the adjusting item and inner sleeve within the outer pipe.
