Sistem perpipaan merupakan peralatan untuk mengalirkan fluida dari satu peralatan ke peralatan lainnya. PT Jakarta Tank Terminal (JTT) yang bergerak dibidang jasa penyimpanan produk memiliki sistem perpipaan yang digunakan untuk mengalirkan produk Mogas dari tangki timbun ke mobil tangki. JTT akan melakukan pengembangan phase 2B yaitu pembangunan tangki timbun TK0305 dan sistem perpipaan sampai ke pipa header suction pompa 33LP0001 sepanjang 162 m pada area tank farm 3 dengan mengalirkan Mogas ke truck loading bay menggunakan kapasitas alir 750 m3/h. Sistem perpipaan harus dirancang dengan aman sesuai dengan kondisi operasi yang mengacu pada standar ASME B31.3, sehingga kebocoran dan biaya berlebih pada pembangunan sistem perpipaan tersebut dapat dihindari. Dari hasil analisis didapatkan diameter nominal pipa sebesar 14 inchi. Material pipa yang dipilih adalah ASTM A53 Grade B. Tebal dinding pipa yang dipilih yaitu 0,375 in (SCH 30 ST) yang mampu mengakomodasi corrosion allowance 0,0591 in. Jarak support maksimum yang didapatkan yaitu 13,526 m karena aman terhadap defleksi maupun tegangan pipa. Pada perancangan sistem perpipaan ini, fleksibilitas dari parameter dan jalur pipa yang direncanakan dapat dipenuhi. Analisis stress sistem perpipaan ini dilakukan dengan menggunakan aplikasi Caesar II dengan pembebanan sustain, expansion, operational dan hydrotest didapatkan hasil tegangan tidak melebihi allowable stress material pipa yaitu 30.000 psi sehingga sistem perpipan dikategorikan aman untuk dioperasikan.
