Does not satisfy June 2007 API 579-1/ASME FFS-1 Level 1 assessment.
(Refer To: June 2007 API 579-1/ASME FFS-1 )
Analysis done according to June 2007 API 579-1/ASME FFS-1
Step 1: Determine the minimum required thickness.
TminL = 0.320 in
TminC = 0.675 in
Tsl = 0.000 in
Tmin = 0.675 in
Step 2: Evaluate the thickness data.
Tmm = 0.397 in
Step 3: Determine the wall thickness to be used.
Tc = 0.397 in
Step 4: Determine the remaining thickness ratio.
Rt = 1.000 in
Step 5: Determine the length for thickness averaging.
Q = 50.000
L = 138.029 in

TamC = 0.397 in
TamS = 0.397 in
Step 7: Determine the acceptability for continued operation.
TamS - FCA >= TminC ? No: 0.397 < 0.675
Averaged longitudinal thickness must be greater than t_minC.
TamC - FCA >= TminL ? Yes: 0.397 >= 0.320
Tmm - FCA >= 0.338 ? Yes: 0.397 >= 0.338
MAWPr = 807.222 psi
MAWPr >= MAWP ? No: 807.222 < 1350.000
MAWPr must be greater than Design Pressure.
Part 4 Level 2MAWPr must be greater than Design Pressure.
