Offshore J-tube Centralisers prevent the supported line from touching the inside of the tube into which they are being pulled, preventing abrasion damage. Centralisers are installed onto the cable or pipe prior to deployment and pulled in as one unit. 

• J-tube Centralizors are engineered to centralize Umbilical, Riser and Flowline with J-tubes & j-tube bellmouths. By umbilical type (hydraulic umbilical and electro-hydraulic and electro-fiber optical hydraulic umbilical with medium voltage cores) and by riser type (production riser, drilling riser, work over riser, and others). Durable and soft J-tube centralisors prevent the host line kinking, crimping and breaking

• Easy to install polyurethane J-tube seals feature a tapered design that simplifies installation and provides a secure fit. The inside lip of the sub-centraliser attaches to the coupling, locking the restrictor in place.

• Additionally, split shell J-tube centralizers can be specified to maintain the cable position within a J-tube while bend restrictors or stiffeners can assist with positioning and stability.

• A typical J-tube Centralizor comprises three key components:

The clamp

The seal

The nose

Standard color: Yellow

• Sub-sea J-tube seal is used to provide sealing and corrosion protection between flexible umbilicals, cables or pipes and the J-tubes found on offshore installations. They are widely used in the windfarm,oil & gas,offshore, deepwater and renewable energy sectors.

• J-tube centralizer for 3x120mm2 35kV, J-tube centralizer for 3x70mm2 35kV. Philson provide both types of diverless and diver-installed offshore J-tube centralisers that are available in a range of sizes for pre- or retrofitting.
