ABSTRAK PT. ALSTOM adalahperusahaan global yang bergerak di bidang Power Boiler yang berpusat di Perancis. Saat ini PT. ALSTOM sedang membangun proyek untuk membuat modul HSRG Power Boiler, yang dinamakan proyek “Thai Oil”. Sesuai dengan SWDS proyek “Thai Oil”, pada sambungan Nozzle to header dilakukan proses mechanical straightening setelah dilakukannya proses pengelasan karena terjadi deformasi lebih dari 1mm pada bagian header pipe. Namun, proses mechanical straightening ini membuat waktu produksi menjadi lebih lama, sehingga perlu adanya perancangan alat bantu berupa jig untuk mencegah dan mengurangi deformasi pada header pipe tersebut. Dalam penelitian ini dibuat 2 variabel, antara lain simulasi deformasi header pipe sebelum diberi Jig dan sesudah diberi alat bantu berupa Jig. Desain dari sambungan Nozzle to Header berdasarkan drawing PT.ALSTOM, yang kemudian disimulasikan dengan menggunakan software ANSYS R15.0. Hasil dari simulasi sambungan Nozzle to Header ini menghasilkan output deformasi sambungan Nozzle to Header kurang dari 1mm, dengan menggunakan alat bantu Jigging and Fixturing ini ternyata mampu mencegah dan mengurangi deformasi pada header pipe setelah dilakukannya proses pengelasan, dan juga dapat menghilangkan proses mechanical straightening. Kata Kunci: Nozzle to Header, Mechanical Straightening, Deformasi, Jigging and Fixturing. ABSTRACT PT. ALSTOM is a global company of power boiler fabricator that centered in France. In the present PT. ALSTOM has build the project of HSRG Power Boiler, that named “Thai Oil”project.Based on the SWDS of “Thai Oil”project, on joint ofNozzle to header mechanical straightening process is carried out subsequent to the welding process , due to deformation of more than 1mm on the header pipe . However , this makes the process of straightening mechanical productiontime becomes longer , so there needs to be Jig design tools to prevent and reduce deformation on the pipe header. In this study made 2 variables , such as simulated deformation header pipe before the jig was given and after the given tools such as Jig . The design of the connection nozzle to a header by drawing PT.ALSTOM, then simulated using ANSYS R15.0 software. The results of the simulation connection nozzle to the header of this deformation generates output nozzle connection to the header of less than 1mm , by means of jigging and fixturing help proved capable of preventing and reducing deformation in the header pipe , subsequent to the welding process , and also can eliminate the mechanical process of straightening. Key Words: Nozzle to Header, Mechanical Straightening, Deformation, Jigging and Fixturing.
