PERHITUNGAN TEKANAN OPERASI MAKSIMUM BOILER
Galvanized steel pipe dengan diameter luar (D) 6 inch dan tebal (t) 0,17 inch

difungsikan sebagai boiler dalam penelitian ini. Material yang digunakan adalah carbon
steel ASTM A 36.

Berdasarkan ASME section 2 Part A, allowable tensile stress (S) adalah ¼ dari
ultimate strength, pada tabel 5 dibawah ini ditunjukkan Su (ultimate strength) adalah 60

ksi (60000 psi). Maka allowable tensile stress (S) adalah 15 ksi (15000 psi).

Berdasarkan ASME Process Piping code B31.3-1999, persamaan untuk
menentukan Maximum Piping Operating Pressure yang memberikan hubungan antara
pressure (p), diameter luar pipa (D), allowable tensile strength (S) dan tebal pipa adalah

[14]:
(1)
Dimana : E= Longitudinal Weld Joint Quality Factor yang ditentukan ASME Process
Piping code B31.3-1999, tabel 302.3.4
Y= wall thickness coefficient yang ditentukan ASME Process Piping code

B31.3-1999, tabel 304.1.1
Untuk material ASTM A 36 nilai E dari tabel 302.3.4 adalah 0,8 dan Y dari tabel
304.1.1 adalah 0,4 dengan temperatur operasi boiler < 482 oC.
Persamaan (1) dapat dituliskan kembali,
(2)
Sehingga tekanan operasi maksimum dapat ditentukan dengan persamaan (2).

Hasil perhitungan menunjukkan tekanan operasi maksimum boiler adalah 695 psi (48,8
kg/cm2), sedangkan kebutuhan tekanan boiler pada penelitian hanya 71 psi (5 kg/cm2).
