Stainless Steel Air Conditioning Drain Tube

Specially engineered for metro, high-speed rail and other rail transit vehicles, our stainless steel air conditioning drainage system is the core component ensuring efficient discharge of air conditioning condensate and car body rainwater. It is deeply compatible with key vehicle structures such as Door frame assembly and side beam, providing strong support for the safe and stable operation of urban rail vehicles. The core drain pipe of this system is made of high-quality 304/316 stainless steel and high-strength carbon steel, precisely manufactured via advanced cold-bending forming technology. Unlike traditional pipes, it features customized cross-section design for special shaped pipes and profiles based on the vehicle's internal space layout and drainage path. This design perfectly fits the complex vehicle body structure, maximizes limited space utilization, achieves vehicle lightweighting by reducing weight by approximately 25% compared to conventional pipes, effectively lowers en…
