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.
