Jawab
a.
tm = t + C
t = PD / 2 (SE + PY )
SE pada 680 F
= 16.88 Ksi
= 16880 psi
Tabel ASME
Y = 0.4
D = 10.75 in see ASME 36.10
Maka
t = 1200 psi . 10.75 inc / 2 ( 16880 psi + 1200 psi. 0.4)
= 0.372 Inch
Penyelesaian
Maka
t = 1200 psi . 10.75 inc / 2 ( 16880 psi + 1200 psi. 0.4)
= 0.372 Inch
tm = t + C
= t + CA + CM
= 0.372 inch + 0.0625 inch + 0.05 inch
= 0.4845 In
Jadi Wall thickness secara teorical 0.4845 in
b. Minimum nominal wall thickness adalah
Reffer to ASME 36.10
