Transcript of Piping Design Review

  • Pertimbangan utama adalah SafetyProsedur, notifikasi, instruksi,WI,SOP.Evaluasi Kondisi ProsesTemperaturePressureChemical compatibility/Corrosion allowancesVibration, flexing, bendingExpansion/Konstraksi karena perubahan temperaturEnvironmental conditionsEvaluasi pengaruh kebocoranEvaluasi situasi terhadap kebakaran

  • Pertimbangan selanjutnya

    Evaluasi terhadap keadaan khususKeadaan sanitari KebersihanMampu servis kemudahan perawatanKemungkinan kontaminasi material pipa, gasket terhadap fluidaLowest Cost over the Lifetime

  • Untuk Design pipa gas seperti NCG. Perhatikan slope dalam pemasangan untuk antisipasi condensate.Design pipa hydrogen. Ingat untuk membuat seal pot pada posisi tertentu, untuk membuang condensateSemua Outlet/Discharge pump pipa sampai dengan contral valve, menggunakan schedule/grade setingkat di atas pipa distribusi atau > sch 20Pipa tidak boleh masuk paritPertimbangkan pipe spool untuk memudahkan maintenance terhadap equipment

  • Support sekitar equipment mencegah perpindahan berat terhadap equipment flanges

  • Vertical pipe support- Gunakan spring hanger bila pipa tersebut mengalami pemuaian

  • PIPE SUPPORT INTERVAL RUN
