Perancangan Sistem Jalur Perpipaan Distribusi Suplai Udara Sistem Pneumatik Di Stasiun Pengumpul Tapen

Abstract

This research presents the design of a pressurized air piping system for pneumatic valves
and indicator control in the metering and separator units at Gathering Station Tapen. The system is
intended to distribute compressed air required by pneumatic actuators to operate valves via air inlet
ports, controlled by signals from a Programmable Logic Controller (PLC). The design uses Carbon
Steel A106 Gr B galvanized pipes and stainless steel 304L tubing, referencing ASME B31.3 and CAGI
standards. Air capacity requirements for each component were calculated to determine the total system
demand, while pressure drop calculations were performed both manually using the Darcy-Weisbach
equation and via fluid flow simulation software. Results show a total air demand of 2,911 liters/minute
for 19 components, with a total pressure drop of 0.4381 bar, which is within safe limits (below 10% of
the compressor’s 10 bar output). The simulation yielded a pressure drop of 0.4375 bar, with only a
0.13% error compared to manual calculations. These findings confirm that the design is safe and
efficient for operational needs
