J-tube centralisers serve as a pivotal component in protecting subsea pipelines from corrosive elements present in seawater. In the demanding offshore marine environment, the integrity of pipeline systems is critical to operational success and safety. As a custom seal manufacturer, we understand that corrosion can severely compromise the stability of pipelines, leading to potential leaks and costly repairs. Our J-tube seals provide a long-term barrier at the interface between the umbilical/flexible riser and the inside of the J-tube, effectively preventing seawater ingress and the subsequent degradation of vital components. 

Centralising action

One of the standout features of J-tube centralisers addon is their centralising action, which ensures the accurate positioning of cables or umbilicals within the J-tube during installation. The seal clamp is designed to attach a series of bend restrictors, providing essential protection against overbending within free spans. This feature not only enhances the longevity of the cable but also maintains the structural integrity of the entire system. With our established range of standard and quick-install bend restrictors, we are equipped to meet diverse project requirements efficiently.

Easy installation

Designed specifically for the challenges posed by subsea environments, offshore J-tube centralisers utilize polyurethane split shell technology, which allows for an interference fit with the host line and the J-tube bore. This design eliminates the need for subsea activation, drastically simplifying the installation process. Moreover, our modular design is diverless, allowing for installation without the need for underwater divers, thereby reducing project time and costs while enhancing safety.

Reduce corrosion

Usage scenarios for our J-tube centralisers span various industries, including oil and gas structures and the offshore wind sector. In these applications, where pipe connections are particularly susceptible to corrosion due to the natural acidity of seawater, our seals act as a safeguard. By retaining corrosion inhibitors within the J-tube annulus, our centralisers ensure that essential protective agents remain effective, thus prolonging the service life of the piping systems and minimizing maintenance needs.

Customization 

Customisation is at the core of our product offerings. We recognise that each project has unique specifications; therefore, bespoke configurations of J-tube centralisers are available to accommodate varying cable sizes ranging from 90mm to 300mm. This adaptability allows us to cater to specific installation criteria while ensuring optimal performance across different subsea conditions. 

Cable handling accessories are engineered to deliver superior performance and reliability in harsh offshore settings. By preventing corrosion, facilitating easy installation, and offering robust protection for subsea cables, Philson centralisers stand out as a crucial investment for any subsea energy solution. As a trusted custom seal manufacturer, we are committed to providing innovative sealing solutions that enhance operational efficiency and safety for our clients in the oil and gas and offshore wind industries.
