Abstract: Heavy duty truck air compressor ventilation pipe material, usually using precision colddrawn galvanized seamless steel pipe reprocessing, reprocessing and transportation of the pipe surface coating is easy to be scratched, rust resistance decline, at the same time electroplating passivation process will produce a lot of waste liquid, affecting the environment. Aluminum alloy material itself has a good corrosion resistance, through the bending performance of aluminum alloy seamless pipe, corrosion resistance, sealing, heat resistance and economic and other aspects of the comparative analysis, aluminum alloy seamless pipe meets the requirements of air compressor ventilation pipe, is a good alternative pipe material for air compressor steel pipe.

Key words: Air compressor; Aluminum alloy pipe; Corrosion resistance; Sealing performance; Alternative pipe material
