Deficiencies Summary Deficiencies for Kettle reboiler TEMA RCB-3.13: The shell thickness is less than the required minimum thickness of 0.3125 in. TEMA RCB-4.52: The unsupported straight tube span exceeds 69 in. TEMA RCB-3.13: The front channel thickness is less than the required minimum thickness of 0.3125 in. TEMA RCB-3.2: The rear closure thickness is less than the required minimum thickness of 0.3125 in. TEMA RCB-3.2: The front channel closure thickness is less than the required minimum thickness of 0.3125 in. Deficiencies for Saddle Shell bending stress at the saddle is excessive. Circumferential stress at the wear plate horns is excessive. Deficiencies for SS Inlet (N4) Nozzle MAWP (56.1229 psi) is less than the design pressure (60.3041 psi). The inner fillet weld (Leg41) is too small., MAP condition per UW-16 Deficiencies for SS Outlet (N3) The inner fillet weld (Leg41) is too small., MAP condition per UW-16 Deficiencies for SS Outlet 2 (N5) Nozzle MAWP (59.2441 psi) is less than the design pressure (60.3041 psi). The inner fillet weld (Leg41) is too small., MAP condition per UW-16 Deficiencies for TS Inlet (N1) Due to size or thickness limitations, SA-455 3*t = 3*0.125 = 0") is not recommended and may produce excessive secondary stresses in the welds. (warning) Nozzle thickness in excess of three times the vessel plus pad thickness (tn = 1.062" > 3*t = 3*0.1875 = 0") is not recommended and may produce excessive secondary stresses in the welds. (warning) Nozzle does not satisfy the specified minimum projection length of 6.0000" (warning) Warnings for Tube Side Flange (front) TEMA, Table D-5: Current bolt circle (19.25 in) does not provide sufficient wrench clearance, 19.5 in recommended. (warning) TEMA, Table D-5: Bolt washers will extend beyond the flange outer diameter. (warning) This body flange is being counted as a line of support for external pressure. (warning) Warnings for Vessel No baffles specified. Vessel weight and weight distribution may not be correct. (warning)
