The production of compressed air in industrial activities is a requirement for a multitude of applications. It is used for the control and regulation of appliances and as the driving force for pneumatic drills, machine tools, pneumatic conveyors, spray guns, etc.
To ensure that the appliances using compressed air function correctly the quality of the air employed must be excellent. In multilayer pipes the surface of the pipe that comes into contact with the conveyed fluid (in this case air) is made of crosslinked polyethylene and unlike metal pipes, this guarantees the absence of rust and impurities formed by condensation that could become detached from the pipe walls.
Cleaner air also means that the filters require less maintenance. Moreover, the mechanical characteristics of multilayer pipes make them suitable for use at very high operating pressures: at room temperatures, Pexal and Mixal can be used for systems operating at 16 bar. In such cases, it is recommended to use technopolymer fittings (PPSU): compared to those in brass they are more resistant to the corrosion caused by acidic condensation that is sometimes generated during the air compression process.
These are the advantages of using Valsir multilayer pipes in compressed air distribution systems:
- Complete resistance of both the pipes and the fittings to acidic condensation.
- Increased quality of the air in the system (no rust particles become detached from the pipe walls).
- Extremely low pressure drops if Pexal Easy fittings are used.
- Pipes are available in coils.
- Rapid installation.
