Vertebrae Bend Restrictors Manufacturer in China
What is a Vertebrae Bend Restrictor?
A Vertebrae Bend Restrictor assembly is an essential cable protection system device. It is mounted around subsea cables or pipes and securely attached to a rigid structure. Its primary function is to prevent the cable or pipe from bending beyond its designed locking radius, effectively safeguarding it from overbending and potential damage.
How Does a Vertebrae Bend Restrictor Work?
Vertebrae Bend Restrictors are manufactured using high-performance materials such as polyurethane. They are specifically designed to protect pipes and cables at critical interfaces between flexible and rigid structures. The restrictor consists of multiple interlocking elements that react under external load by locking together to form a smooth, fixed radius. This radius is carefully designed to match or exceed the minimum bend radius of the pipe or cable it protects. Once locked, the bending moment is transferred through the restrictor elements and into a specially engineered steel interface structure, thereby diverting damaging loads away from the pipeline or cable.
