CONTOH
Pada sistem perpipan diketahui
Tentukan
a. Ketebalan minimum yang diperlukan secara teorical
b. Ketebalan Minimum (Nominal wall thicknes) sesuai ASME 36.10
Penyelesaian
Mechanical Allowance : 0.05” Ditanya
a. Ketebalan minimum yang diperlukan secara teorical
b. Ketebalan Minimum (Nominal wall thicknes) sesuai ASME
36.10
Penyelesaian
Jadi Wall thickness secara teorical 0.4845 in b. Minimum nominal wall thickness adalah
