Polyurethane submarine cable protective tubes are essential components used in offshore and subsea cable protection systems. Designed to shield cables from mechanical damage, abrasion, and environmental stresses, these protective tubes ensure long-term reliability and performance in harsh marine conditions.
Product parameters
Material: High-performance polyurethane (PU)
Hardness: 50A – 70D (customizable)
Inner diameter: Ranges from 50 mm to 300 mm, customizable based on cable size
Wall thickness: Typically 10 mm to 25 mm, depending on application
Temperature resistance: -40°c to +80°c
Color: Standard yellow, customizable
Length: Produced in segments or continuous lengths as per project needs
Reinforcement options: Optional embedded iron rings or fiber layers for added strength
Functions
Mechanical protection: Absorbs external impacts, preventing cable crushing or deformation during installation and operation.
Abrasion resistance: Resists wear from sand, rocks, and constant contact with marine structures.
Flexibility: Maintains flexibility under high-pressure or deepwater environments, allowing easy handling and routing.
Corrosion resistance: Unaffected by saltwater, oils, and chemicals commonly found in offshore environments.
UV & aging resistance: Offers long-term durability when exposed to sunlight and marine atmosphere.
Usage scenarios
Offshore wind farms: Used to protect export and inter-array cables from damage at the seabed or near cable entry points.
Oil & gas platforms: Provides reliable protection for dynamic and static subsea umbilicals and power cables.
Underwater pipelines and risers: Serves as a safeguard where cables run parallel to or intersect with pipelines.
Port and coastal infrastructure: Ideal for cable installations under wharfs, docks, and bridges.
ROV and subsea equipment connection: Ensures cable integrity in zones with frequent movement and vibration.
Polyurethane submarine cable protective tubes offer a dependable solution for ensuring the longevity and safety of subsea power and communication cables. It is also a cable and flowline crossing protection. With high resistance to environmental factors and mechanical stress, they are indispensable in modern offshore energy and marine engineering projects.
