Expansion joints for Scrubbers or Exhaust Gas
Cleaning Systems on ships


Customised solutions for Scrubbers

Many of today's ships are old and no one could think of the need to install equipment like scrubbers on their gas exhaust systems. This makes the installation on ships sometimes complex due to lack of space, lack of information, etc.

MACOGA cooperates with designers, manufacturers, users and scrubber installers and helps to find the optimal Expansion Joints according to their needs.



Most of the Expansion Joints that are used in scrubbers are our MFG Series Single Unrestrained or Universal Unrestrained MFD Series with floating flanges.


The specific application in the scrubber determines the materials to be used but the Expansion Joints are generally supplied with the bellows manufactured in 254SMO (1.4547) UNS S31254 and the rest of the components (flanges, pipes, etc.) in Alloy C276 (2.4819) UNS N10276 or AISI 304L, 309L, Duplex, etc.
