Diver installed J-tube or I-tube bungs may be fitted around the host umbilical or flowline. They are typically positioned just behind the entry bellmouth. The bung may be used as a flow restriction device to limit the loss of the corrosion inhibitor solution present in the annulus between the host line and the J-tube bore.
The product may be used to limit the amount of flow in to and out of the J-tube annulus.
J-tube bungs can also be used to centralize a cable, umbilical or flowline within a J-tube or I-tube.
The design utilizes a polyurethane seal which deforms during installation to provide interference fit to the host line and the J-tube or I-tube bore.
To meet our customers' needs, our cutting-edge solution can be used for the below application.
