Based on one large amphibious aircraft, some problems of tube design in air-bleed and air- conditioning system were discussesd, such as resistance calculation. Pipe layout, lfow resistance calculation, hot stress compensation and pipe installation were analyzed. Take the large amphibious aircraft as example, its pipe diameter was designed, the resistance of the tube system was calculated, which proved the design satisfy design requirements. Its hot stress was calculated, determined the number of stainless steel bellows compensator. The design principle and caculation formula this paper provides, has certain versatility, provides a reference for environmental control systems designers.
