I have a situation where a furnace is operating at 1922F with 3/4" Sch40 tubes. The Boiler & Pressure Vessel Code publishes allowable stress values up to 1650F. Does anyone have a recommendation for finding allowable stress values above 1650F for SB-407 N08810 pipe?
Can anyone recommend a book or article for an introduction into HVAC programming for residential control units? I am not looking for complex controls for large industrial buildings. Just fundamentals and basics.
