Steam Pipe Heat Loss Through Support Shoe

Have a look at Pipemill ..... as advertised at the top of this page. It contains many programs, one being support shoe heat transfer prediction for three shoe configurations.

Before anyone gets too emotional about "Heat Loss Calculations for Pipe Shoes" there should be a rational consideration for the type of insulation (Hot vs Cold) and all areas and types of heat loss.

Hot Insulation - Here a pipe shoe, a "Dummy" pipe support or any Trunnion type of extension welded directly to the pipe will provide a path for (conduction) heat transfer and loss, but this is very small when compared to other items. Items that are not insulated and provide a greater surface area and radiant heat loss include all the flanges and the valve bodies.


Cold Insulation - Here all areas are insulated. This includes valve bodies. Pipe supports are normally isolated from direct contact with the containment pipe by a non heat conductive material or as in the case of a direct welded "Dummy" support the Insulation would be extended on the Dummy for a distance of 5 times the insulation thickness.
