Summary

05/01/2023 Pipe Installation for Air Compressor & Air Dryer 2

• 2 sets of Air Compressor and Air Dryer are required to be installed in

the manufacturing factory due to increase in workload.

• An appropriate pipeline is required to transfer the compressed air to

the Air Receiver of the factory.

• Completion time: 7 weeks. Due to higher workload and priority in

other sections of the factory, manpower was reduce hence project

was delayed.

Air Compressor

compressed air.

• 2” Valve: Grade PN25

• 6” Valve: Universal

Butterfly Valve

• Valves are capable of

withstanding 0.7MPa of

compressed air.

Flange and Gasket

• Flange are used to connect

two ends of pipes together.

• Slip-on flange is used, which

is welded at the end of the

pipe.

• Flange: Grade PN16

• Gasket: Paper Gasket (to

prevent air leakage)

Pre-Filter and After-Filter

• Manufacturer: FRIUL AIR DRYERS

• Model: FT*160

• Function: To remove impurities.

• Maximum flow rate: 16.8m3/min

• Air Inlet and outlet size: 2”

Pipes

• Pipe type: Galvanized Iron

• Pipes sizes used: 2” and 6”

• 2” pipes: Direct compressed

airflow from compressor to

dryer. Outlet of dryer is then

welded to 6” pipe (header).

• 6” Pipe: Direct airflow to the

air receiver tank.

Drainage System

• Drain out wet air and release

using pressure relief valve.

• Nylon tube is used to direct

the wet air to the drain.

Loops

• Loops are used throughout

the 2” pipelines.

• Create a bypass for the

compressed air to prevent it

from going into faulty

machineries or parts.

• Allows the compressed air

to flow continuously even

when there’s faulty parts.
