Njord J-Tube S (Seals)

Njord J-Tube B (Bungs)

Njord J-Tube B 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

Polyurethane seal elements are used to provide an interference fit to the host line and the J-tube bore. The interference fit provides the seal – no subsea activation procedure or intervention is necessary.

Corrosion inhibitor retention

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