Aluminum alloy in the system pipe to pipe connector role
1. It can optimize the efficiency of air transmission
Low friction transmission: aluminum alloy inner wall is smooth (roughness ≤ 0.003mm), which can reduce the resistance of compressed air flow, and the pressure drop is reduced by 30%-50%.
Seamless structure: one-piece molding technology to reduce leakage points, to protect the system airtight (leakage rate <0.1%).
2. Resistant to environmental and media corrosion
Oxide film protection: the surface Al2O3 layer can isolate water, oil and acidic impurities, to avoid corrosive media infiltration, to extend the life of the pipe.
No secondary pollution: can eliminate the steel pipe corrosion particles mixed into the compressed air, to protect the precision manufacturing industry (such as semiconductor, medical) with the cleanliness of the gas.
3. Can reduce the overall cost
Installation cost: Quick-fit module design can reduce the need for 90% welding, installation efficiency increased by 60%.
Maintenance costs: maintenance-free features can reduce the frequency of maintenance downtime, the average annual maintenance cost is only 20% of galvanized steel pipe.
