We are pleased to announce the successful completion and delivery of a large-diameter high-pressure expansion joint, MRR Series, to a major Petrochemical Plant in China.

Key features of the Expansion Joint:

  • Type: MRR
  • Nominal Diameter: 5000 mm
  • Bellows Material: SB409 N08810 (Alloy 800)
  • Reinforcing Rings: SA-182 F304H
  • Pipe Ends: SA-182 F304H
  • Test Pressure: 7.7 barg

The MRR Series are used in cases of high internal pressures and/or equalizing the movement among all the corrugations. The system involves the use of 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.

This robust design and high-quality materials ensure optimal performance and reliability in demanding applications.

The ASME certification serves as a testament to MACOGA's unwavering commitment to maintaining the highest standards of quality, safety, and reliability in the design and manufacturing of expansion joints.
