What is an elbow?
An elbow is an indispensable connection in an aluminum compressed air piping system, used to change the direction of the piping. It is usually angled at 90° or 45°, and can be customized to other angles according to actual needs.
The function of the elbow:
Changing pipe direction: Elbows enable piping to bypass obstacles or adapt to space constraints, enabling flexible piping layouts.
Reduce pressure loss: Quality elbow design can reduce airflow resistance, reduce pressure loss and improve system efficiency.
Enhance the stability of the system: elbow to ensure that the pipeline connection is tight, to prevent leakage, to protect the stable operation of the system.
Features of aluminum elbow:
Light weight and high strength: Aluminum alloy makes the elbow light weight, easy to install, and at the same time has good strength and corrosion resistance.
Corrosion resistance: the oxide film formed on the surface of the aluminum alloy can effectively resist corrosion and extend the service life.
Easy to install: Using quick couplings or threaded connections, easy to install, saving time and cost.
Aesthetically pleasing: The surface is anodized, which is not only aesthetically pleasing, but also further enhances corrosion resistance.
Environmental protection: aluminum alloy can be 100% recycled, in line with environmental requirements.
Advantages of choosing aluminum elbow:
High efficiency: optimize airflow, reduce pressure loss, improve system efficiency.
Durable: Corrosion and wear resistance, long service life.
Economy: low installation and maintenance costs, long-term use of more economical.
Reliable: to ensure stable operation of the system, reduce failure.
