Webe = Thickness Factor (0.04 for expanded tubes; 0 = for strength welded tubes); S = Maximum Allowable Stress According to ASME Section II. Example - Boiler Tube: Calculate the minimum required wall thickness of a water tube boiler 2.75 in O.D., strength welded (E, or, e = 0) into place in a boiler. The tube has an average wall temperature of 650°F. WebThis will result in a larger minimum wall thickness for the 30 day post-accident condition service life case at 1750F for the HDPE Return Lines. Therefore, it is conservative to use 340 psi. For Information Only: 3.3 Assumption: The allowable stress value for the HDPE Return Lines for a post-accident shipping courses
