J-Tube Bungs - Cable and Flowline Protection - Subsea - Trelleborg Offshore

J-Tube Seals

J-Tube Seals are used to prevent the loss of corrosion inhibitor solution used in the annulus between the hostline and the J-Tube bore.

Diverless and modular design

The seal is secured to the host line by integral clamps. It can then be pulled into the J-Tube or I-Tube with the host line. Typically the seal will be installed in the J-Tube just behind the entry bellmouth.

Interference fit

Polyurathane seal elements are used to provide an interference fit to hold the host line and the J-Tube bore. The interference fit provides the seal - no subsea activation is necessary. 

Corrosion inhibitor retention

J-Tube seals are primarily used to prevent the loss of corrosion inhibitor within the J-Tube annulus.
