Analisis Dua Desain Sambungan Pada Sistem Perpipaan Crude Oil Untuk Rekomendasi Instalasi Proyek Perpipaan

Abstract

Piping installation is a system of installing and arranging pipes and their complementary to flow fluids in industrial facilities or distribution systems. There are constraints in selecting connections in an oil and gas facility, so the consultant provided the owner with welding and flange connection options to provide technical convenience. This study aims to provide recommendations for connection options using technical analysis. Stress analysis was conducted using manual calculations and stress analysis software according to the ASME B31.3 standard. The main parameters analyzed include stresses due to sustain and expansion loads. The manual calculation results show that flange joints have lower sustain and expansion stresses than welding joints. However, the software results show a significant difference, where welding joints have lower expansion stresses (9316.400 psi) than flange joints (10872.0 psi), while the sustain values for both are almost the same. Because expansion stresses are strongly influenced by thermal loads during operation and impact pipe service life, welding joints are considered safer and more stable in the long term. The conclusion of this study recommends the use of welding joints in crude oil piping system installations to minimize the risk of failure due to thermal expansion loads.
