Dynamic and static universal polyurethane bending stiffener reinforcement

In dynamic applications, polyurethane bend stiffeners need to have sufficient fatigue resistance to control the bending radius in use and maintain the cyclic load to the specified service life, while in static applications, they must prevent total bending.
The stiffeners are usually conical shaped polyurethane moldings with cylindrical holes that slide on pipes, umbilicals or cables.
Information critical to the design of curved stiffeners includes:
      Tension and angle data for riser analysis;
      temperature;
      Interface details;
      Stand pipe end fittings;
      Diameter and stiffness;
      Minimum bending radius.
