Polyurethane deepwater J-tube seals are used to seal the interface between the umbilical / flexible riser and the inside of a J-tube, incorporating a water tight seal in which an anti corrosion inhibitor is often introduced. Manufactured from high-performance polyurethane, this guide seal clamp is designed to withstand the harshest deepwater conditions, offering exceptional resistance to wear, impact, and corrosion.
Key features
Superior durability: High-grade polyurethane construction ensures long-lasting performance, even in challenging subsea environments.
Easy to install：Manufactured from high marine grade polyurethane and of split shell, modular construction, our J-tube seal solutions allow ease of installation.
Enhanced cable protection: The guide seal design provides precise alignment and support, minimizing the risk of cable damage during installation and operation.The seal provides a long term barrier, prohibiting corrosion by preventing seawater from entering the J-Tube.
Optimized fit: Customizable clamp dimensions ensure compatibility with various J-tube diameters, project specifications, and cable sizes.
Corrosion & impact resistant: Engineered to withstand deepwater pressures, saltwater corrosion, and mechanical impact.
Applications
Offshore wind farms：J-Tube Cable/Umbilical Entry Points: Prevents ingress of debris and water.
Oil & gas platforms infrastructure: Risers, manifolds, and subsea control modules.
