Deep Down manufactures bend limiters in both polyurethane and steel to fit any flexible flowline, umbilical, cable, or flying lead. Designed and manufactured to customer specifications based on the minimum bend radius, outer diameter of the product they are encompassing, and the static and dynamic loads, these bend limiters provide excellent protection for limiting the bending radius of the product.
The steel bend limiter design is capable of handling large loads and includes a simple, reliable hinged attachment system that significantly reduces installation time. Polyurethane bend limiters provide similar support for smaller diameter umbilical, cables and flying leads.
Bend limiters usually comprise a number of interlocking elements which articulate when subjected to an external load and lock together to form a smooth curved “locking” radius. This radius is chosen to be equal to or greater than the minimum bend radius of the pipe that it is applied to. Once the elements have locked together, the bending moment present is transferred into the elements and back through a specially designed steel interface structure into the adjacent rigid connection, therefore protecting the pipe from potentially damaging loads.
