J-Tube Seals.
J-Tube Seals [Metallic & Polymeric]
Our J-Tube seals are engineered to handle a wide range of applications, accommodating J-Tube diameters up to 36” NS and cable or umbilical ODs up to 350 mm. Designed to API 17 L1/L2 standards, they are available in metallic, polyurethane, and nylon materials, with design pressures exceeding 5 bar G. We offer diverless, diver, and active configurations to meet diverse subsea operational requirements.
OUR TRACK-RECORD
We have a broad track record for J-Tube Seals, covering multiple diameters, pressure ratings, and installation methodologies. Our portfolio has been executed for major operators including QatarEnergy, and ADNOC, working through leading EPC contractors such as Saipem, and COOEC. Collectively, our track-record evidences proven capability across global regions including the North Sea, Middle East, Africa, and Asia, reinforcing a product range supported by repeat project awards and multi-specification deployment experience.
