Polyurethane Submarine Cable Bending Limiter Resistance To Water, Oil & Grease

Product Description:

The bending limiter is used for submarine cable bending protection at the lower ports of offshore wind power I pipe and j pipe, and is installed on the buoyancy module outside the marine riser column. Its structure includes semi annular female end, semi annular male end, snap ring, snap groove, auxiliary pipeline channel and riser column channel. The semi annular female end is connected with the semi annular male end through snap ring and snap groove, The snap groove is arranged on the left and right outer sides of the semi-annular female end and is integrated with the semi-annular female end. The snap ring is installed on the semi-annular male end. The snap ring is matched with the snap groove, and the snap ring corresponds to the position of the snap groove.

With the vigorous development of China's offshore oil and gas and offshore wind power resources, the long-term safety and reliability of submarine cables is particularly critical. we provides professional submarine cable protection solutions and corresponding products for various complex marine environments faced by submarine cables. Flexible risers play an irreplaceable role in seabed energy development. Compared with rigid risers, flexible risers have better compliance, can be used in worse environments and have a wide range of applications.

Technical requirements for bending limiter:

1) Modular bite structure is adopted, and the length can be increased or decreased according to the service environment.

2) The module adopts Harvard structure.

3) The Polyurethane material adopts high-quality and reliable products with excellent deformation resistance, corrosion resistance and high wear resistance.

4) The tensile strength of the material shall not be less than 45MPa.

5) The material density shall not be greater than 1.2 × 103kg / m3, requiring no additional weight to the submarine cable underwater.

6) The bending limit shall be able to withstand 8t lateral pressure.

7) The bending radius of the bending limiter shall meet the requirements of small bending radius of submarine cable.

Characteristics of material :

Excellent elasticity, anti-corrosion Resistance to hydrolysis, insulating property.

Protect cable from shocks of anchors with urethane elasticity.

Affinity to cable means no damage to the cable cover.

No abrasion under any marine conditions such as ground or rock subsidence

Excellent anti-corrosion in pipe corroding environment with submarine cables.

Durability of longer than 50 years in submarine environment excellent resistance to hydrolysis.

Excellent surface and dielectric volume.

Workability : basic unit in 1.0m-2.0m means lighter weight and reduced work time.

No need for barge crane or secondary work vessel when laying.
