MRR Series
- Size / DN 3378 mm
- Bellows in Alloy 800H
- 2 ply testable system
- Reinforcing rings in SS 304H
- Temperature: +760 °C
- Test Pressure: 31.0 BARg
- Medium: EB & Steam
MRR Series incorporate reinforcement or equalizing rings located around the outside of the convolution thus preventing the bellows being forced out of shape due to the high pressures.
Equalizing and Reinforcing Rings are devices used on some expansion joints fitting snugly in the roots of the convolutions. The primary purpose of these devices is to reinforce the bellows against internal pressure and equalize the movement among all the corrugations.
MACOGA is a member of EJMA and is recognized worldwide as a leading manufacturer of highly engineered Expansion Joints, which offer reliability and durability to handle high pressure and high temperature requirements.
