Polyurethane static vertebral bend restrictor is a marine cable protection system composed of two symmetrical half shells to prevent excessive marine energy pipelines or cables from bending at rigid interfaces.

Features of the polyurethane bend limiter

• Polyurethane has excellent wear resistance, elasticity, chemical resistance, and high and low temperature resistance -62°C to 93°C (-80°F to 200°F)

• The two-half symmetrical shell design is easier to install

• The vertebral interlocking design has a certain bending range, reaching the bending radius value, which can prevent excessive bending of pipelines or cables at the interface between rigid structures

• The length can be freely adjusted

• Hardness 70 D or 85 D, with certain rigidity and impact resistance, hardness can be customized

• Matching cable diameter 0.5 inch (13 mm) to 16 inches (406 mm), customizable

Use scenarios of vertebral cable bend restrictors

The connection between flexible pipelines, oil flowlines, power cables, umbilical cables, and subsea riser bases, PLEMs, or wellheads. Used in situations where the pipeline is subjected to static or quasi-static loads.

Polyurethane static vertebral bend limiters are important protection solutions for offshore oil and gas, wind power platforms, and submarine communication cables. To manufacture economical, high-quality, and low-maintenance marine energy solutions, Philson provides customers with cable bend protection accessories of different hardness, size, bend radius, and length.
