Pipe, Air, O2


Piping installation is a unified series of pipes or systems to drain fluid to the desired place

by using pipes according to specifications. The piping system is usually equipped with components

such as valves, flanges, elbows, branches, nozzles, reducers, supports, insulation and others. The

Department of Marine Engineering is one of the majors at the Bengkalis State Polytechnic with

facilities and infrastructure, one of which is Pipe and Plate Workshop. The production activities and

the teaching and learning process cannot be separated from the plate cutting and painting processes

that require compressed air and O2. For the effectiveness of the activities in the Pipe and Plate

Workshop, a system for installing compressed air and O2 is carried out. Then the pipe installation

system is tested based on the needs of the work carried out at the Pipe and Plate Workshop. Based

on the test results on the air pipe installation system, the pressure drop at the outlet valve to the inlet

pressure is obtained, namely outlet 1 of 0.1 bar, outlet 2 of 0.3 bar and outlet 3 of 0.4 bar. For the O2

pipe installation system, it is found that the output pressure drop (outlet) to the inlet pressure is large,

namely outlet 1 of 0.38 kg/cm2 and outlet 2 of 0.51 kg/cm2.
