2 PAP (3) Pertimbangan Umum 3 ± Design pressure 1. Internal pressure: P design = (1,05-1,10 ) P operasi. Rase and Barrow, P design =1,2 P operasi z Tekanan hidrostatis pada dasar vessel perlu dipertimbangkan jika nilainya cukup signifikan 2. External pressure: P design =- 1 bar, kecuali dilengkapi dengan vacuum breaker PAP (3) Pertimbangan Umum 4 ± T design = T operasi + 50 o F ± Materials of construction ± Plain carbon steel, low and high alloy steels, other alloys, clad plate and reinforced plastics ± Pemilihannya bahan konstruksi tergantung pada kemudahan pada waktu fabrikasi (welding) dan bahan yang diproses
