In railway vehicles metal bellows and flexible metal hoses provide the necessary flexibility and operational safety in exhaust piping and cooling systems in liquid circuits, braking, hydraulic and transmission systems. In assemblies close to the engine or in the exhaust system in both cases that thermal expansions and vibrations need to be compensated for, specially designed bellows assemblies and spools as well as flexible metallic hoses help users to solve the problems.

Functions of the Bellows & Metal Hoses:

• Compensation of engine movements, vibrations, thermal expansions
• Assuring the tightness of the fluid piping
• Suitability for High Temperature applications and corrosive conditions
• High degree of flexibility, easy assembly
• Reduced thermal radiation and lower pressure drop capability through the inner liner
• High Pressure resistance and mechanical protection by outer braiding
• Design with or without external insulation according to application
