Bend Restrictors

---

Matrix Bend Restrictors consist of a series of interlocking elements which are assembled around a flexible riser, cable or wire to ensure that the minimum bend radius is not exceeded under load. Bend restrictors allow movement and flexibility around the end fitting until the minimum design radius is met. At this point the system mechanically locks and will allow no further movement past the inherent flexibility of the polymeric elements that make up the construction of the restrictors.

Matrix Bend Restrictors are manufactured to API 17J appendix B. All Matrix Bend Restrictors are type proof load tested using a purpose built test rig as part of the design qualification process.

Configuration

---

Matrix Bend Restrictors comprise of a number of interlocking C-Section segments utilizing a split design to allow installation after pipe termination. The C-Section element segments are fastened together using bolts which interlock to the adjacent elements around the riser. The bending movement generated is transferred via the elements to an interlocking reaction collar at the riser termination.
