1 flexible aluminum conduit 

Flexible Aluminum Duct is a piping material consisting of aluminum and steel. Rigid Aluminum Flexible Duct has the light weight and corrosion resistance of aluminum with the strength and pressure resistance of steel. Steel Flexible Tubing is commonly used in piping systems in areas such as construction, industry and automotive. It can be used to convey different media such as liquid, gas and solid. Aluminum steel pipe has good plasticity and can be processed into various shapes and sizes by cold bending, hot bending and welding. In addition, Waterproof And Flame Retardant Plica Tube also has good fire resistance and thermal conductivity, suitable for use in high and low temperature environments.
