Polyurethane cable bend stiffener is used to provide added stiffness to a cable or pipe, preventing excessive bending in dynamic situations with repeated loading cycles

• Function: Bend stiffeners are used to protect risers, flowlines, pipelines, umbilicals, ect. flexible pipelines from over bending at the termination point. Manufactured from an elastomeric material, the Bend Stiffener is suited to the constant wave and current-induced motion of dynamic installations, and can also be used for static applications.

• Buckle mitigation：The conical shape of a Umbilical bend restrictor provides gradual increases in the overall stiffness of the flexible pipe, umbilical or cable, in order to prevent over bending at the termination point.

• Material: Bending stiffeners are normally made of polyurethane material, and their shape is designed to provide a gradual stiffening to the riser as it enters the hang-off location

• Sturdy: The gussets are the crucial parts of the structure, through which all the internal forces from the connected members are transmitted. 

Subsea cable bend stiffeners are important parts needed for connection stiffness and for avoiding plate buckling. A smooth transition is required between the rigid flange and the flexible cone of polyurethane bend stiffener. Bend restrictor achieves this by creating both rigidly bonded and un-bonded areas that provide deflection and minimum stress in these localised areas. The end steelwork on dynamic stiffeners is custom-designed and fully encapsulated to connect with the matching project hardware.

Bend restrictors manufacturer can design and produce in combination with offshore wind power, oil, renewable resource mining and other usage scenarios. Rigidity, length, material and other aspects can be adjusted and customized.
