Pipe shoes for stainless steel piping
Pipe shoes for stainless steel piping
(OP)
I would like to have your opinion about the type of shoe that is more convenient/economic for stainless steel 304 hot pipe (2" to 12", up to 250°F, Sch 10S) with insulation. I have been presented with the following options:
a) SS "wear plate" plus CS shoe welded to wear plate
b) SS "T" shoe welded directly to pipe
c) CS bolted clamps (1 or 2) welded to CS shoe
Please share your experience and recommendations.
Thanks

The majority of ours are used with CalSil.

When using clamps, make sure that they are compatible stainless, or carbon steel with an insulating liner.
RE: Pipe shoes for stainless steel piping
Are they clamps directly clamped to the pipe (with insulation over the clamp) or (as some manufacturers show) they are clamped over the insulation?
If the clamps are CS and installed directly over the SS pipe: is it really required a liner between metals? The CS - SS contact also exists when using CS lap joint flanges with SS stubs and there is no liner there.
Thanks
RE: Pipe shoes for stainless steel piping
As C2it says, if you are going to use CS clamped shoes directly to the SS pipe then you need an insulating layer. Sometimes a 3mm Tico strip is used. Contact a reputable pipe support manufacturer who will have a design to suit your needs.
RE: Pipe shoes for stainless steel piping
If you are going to use a "clamped shoe" design....
Either get a standard "load-rated" design from a reputable pipe suport vendor, or go out and test a few to destruction (not really expensive)
Divide the average destruction load by five....interpolate sizes where necessary
Allowable loads will vary with pipe materials, design pressures and clamp hardware ( U-bolts..?)
