About our RCCP Seismic Movement Joint (SMJ)
Bonna pipe SMJ technology offers a total adaptability to pipeline project:
- Optimization within pipe design
- Seismic conditions
- All types of laying
- Adjustment to major differential settlement
The Bonna SMJ aims to release the excess of stress into the steel cylinder by providing the piping arrangement with local expansion/compression possibilities under seismic-induced movement. SMJ O-rings are procured based on the Procedure MM510 and have proven to be long lasting in multiple projects in hot and marine environments (red sea piping ND 3,000 mm with O-ring connection). In addition, each SMJ is built with a double O-ring thereby increasing the reliability of the seal.
The Bonna SMJ is based on a E-R jointing but is factory prepared and is using a double O-ring. The SMJ has the “free spaces” filled with a foam like substance that is protecting the O-Ring and the 2 end rings from water ingress or corrosion.
