Abstract
Pipa expansion (U-loop) merupakan alternatif yang digunakan
untuk menurunkan dan menjaga tekanan fluida pada kondisi
desain. Penurunan tekanan fluida ini mengakibatkan terjadi
beberapa fenomena pada instalasi pipa expansion (U-loop) antara
lain tegangan, serta aliran fluida. Studi ini ditujukan untuk
mengevaluasi karakteristik aliran fluida yang terjadi didalam
instalasi pipa expansion (U-loop. Studi ini dilakukan secara
pemodelan numerik dengan memodelkan bentuk geometri
exsisting pada instalasi pipa expansion (U-loop) dengan material
carbon steel berdiameter pipa 10” Sch. 80 standart ANSI B36.10.
Studi ini dibantu dengan program lunak ANSYS 11 yang berbasis
finite element methode. Dari hasil simulasi yang dilakukan
didapatkan aliran turbulen yang terjadi pada elbow dapat
menyebabkan getaran pipa, akibat aliran fluida tersebut tegangan
yang terjadi masih dibawah batas maksimum yang diijinkan
sebesar 42,3 Mpa. Sehingga adanya sistem pipa expansion (Uloop)
dapat dijadikan pilihan alternatif yang lebih efisien untuk
meningkatkan serta menjaga integritas sistem secara keseluruhan.

Pipe expansion (U-loop) is an alternative that is used to lower
and maintain the fluid pressure at design conditions. This
resulted in a decrease in fluid pressure occurs several phenomena
on the installation of the pipe expansion (U-loop) among others
stress and fluid flow. This study aimed to evaluate the
characteristics of the fluid flow that occurs in the installation of
the pipe expansion (U-loop. The study was carried out numerical
modeling by modeling the geometrical form exsisting on the
installation of the pipe expansion (U-loop) with material of
carbon steel diameter pipe 10 "Sch. 80 ANSI B36.10 standards.
the study was supported by the ANSYS software program 11
based finite element method. From the results of the simulation
obtained turbulent flow that occurs in the elbow can cause
vibration of the pipe , due to the fluid flow is still below the
voltage that occurs the maximum allowable limit of 42.3 Mpa . So
that the pipe system expansion ( U - loops ) can be used as a more
efficient alternative options to enhance and maintain the integrity
of the overall system
