MACOGA provides high-tech Expansion joints and customized solutions for any marine application.
Expansion Joints are used on the engine for absorbing engine vibrations and movements and thermal expansion.
Nowadays, most large ships use internal combustion engines or gas turbines for propulsion.
These motors generate large amounts of vibration, and these vibrations must be controlled, or they may damage the engine and exhaust system.
Installing one or more metal expansion joints that dampens vibrations is the best way to avoid damage to the engine and exhaust system.
The design of the bellows must ensure that the natural frequency and any harmonics do not coincide with the frequencies of the exhaust system.
These Expansion Joints are generally externally insulated to prevent excess heat from radiating into the engine room.
Exhaust expansion joints must also be designed to absorb thermal expansion and contraction of pipe systems and the whole exhaust system.
For the best performance the Exhaust Gas Expansion Joints must:
