MORGRIP Subsea Pipeline repair Clamps provide a fast and effective way to achieve a subsea pipeline repair. Subsea Clamps are also referred to as Split Sleeve clamps. This description reflects how the body splits in two to enable installation around a subsea pipeline to enable repair. The activation of a split sleeve clamp is achieved through the bolt tensioning of the studs located along the flange where the split occurs. 

A Split sleeve subsea clamp can repair or protect a pipeline while mitigating the need to cut out and replace the damaged section.

All our subsea clamp product lines can be supplied as with a leak sealing or structural capability, with graphite or elstomeric seals to suit your specific application with regards to temperature, pressure and pipe media.
