brake cylinder train parts

We has firstly employed series products of thermal-contracting and seamless welding spinning reservoir specifications of 11, 17, 40, 100, and 150L
Used for railway carriage and freight cars
Such products are developed and produced with high qualified carbon steel and stainless steel tube materials through absorbing and innovating of the core technology of thermal-contracting spinning
Compared to traditional welded steel plate reservoirs, the cylinders produced with this technology is totally free from welding seams, giving an improvement of their quality while increasing the level of the vehicle braking system
