Scope

This recommended practice practice prescribes recommended procedures for calculating the required wall thickness of petroleum-refinery heater tubes for use at elevated temperatures. Utilization of the procedures outlined results in the determination of both design (initial) and retiring (final) tube thicknesses for corrosive and noncorrosive services. This recommended practice is not intended to cover calculations relating to tubes less than 2 in. outside diameter (OD)@ and it is limited to designs where the heat density is 8@000 Btu per sq ft per hour@ or greater.
