Bending restrictor is designed to prevent excessive bending of power, array and communication cables, and umbilical cables. It usually includes multiple interlocking elements that are hinged and locked together when subjected to an external load to form a smooth curved "locking" radius. Choose this radius to be equal to or greater than the minimum bend radius of the pipe to which it is applied. Once the components are locked together, the existing bending moment will be transferred to the components and returned to the adjacent rigid connection through the specially designed steel interface structure, thereby protecting the pipeline from potentially destructive loads.
