3.2.3 Air piping
- Connection to the inlet and outlet of compressed air should be made removable by using union and so
on.
- Secure the piping coupling section with a pipe wrench, connect the air piping fittings.
- Do not allow the weight of the piping to lie directly on the air dryer. When mounting any part such as an
air filter on the fitting at the compressed air inlet or outlet port, support the part to prevent excessive
force from being applied to the product.
- Be careful not to let the vibration of the air compressor transmit.
- Surface temperature of piping will reach to the same temperature as the inlet compressed air. Apply
thermal insulation around the piping when the inlet compressed air is higher than 60
o
C.
- If the temperature of compressed air on the inlet side is higher than 65
o
C, place an after-cooler after
the air compressor. Or, make the temperature of the place where the air compressor is installed lower
than 65
o
C.
- If the air supply makes high pressure fluctuation (pulsation), take any countermeasures such as
installing air tank.
- Flash the piping sufficiently in order to avoid any foreign substances such as dust, sealing tape, liquid
gasket, etc. when piping before piping connection. Foreign substances in the piping can cause cooling
failure or drainage failure.
- Use pipes and fittings that have enough endurance against the operating pressure and temperature.
And connect it firmly to prevent air leakage.
- Provide bypass piping to make it possible to do maintenance without stopping the air compressor.
- When tightening the inlet/outlet air piping, firmly hold the port on the air dryer with a pipe wrench, etc.
- If a metallic flexible tubing is used for the air gateway piping, the allophone might be generated in
piping. In that case, please change to the piping of the steel pipe.
- Please set up the filter in the dryer secondary for the drain dispersion prevention when a rapid
pressure fluctuation and the fluid velocity variation happen.
- Variations in operating conditions may cause condensation to form on the surface of the outlet piping.
Apply thermal insulation around the piping to prevent condensation from forming.
