Conductor Pipe Deck Tensioners
Hannon is one of the industry’s largest manufacturers of Conductor Pipe Deck Tensioners. The company custom-designs and manufacturers systems for use with various size conductor pipes. Hannon’s Conductor Pipe Deck Tensioning Systems consist of a hydraulic power unit (HPU), beam foundation, four jack cylinders and a split reactor ring with three sets of split insert rings. Each system will tension a 48-inch, 42-inch, 36-inch, or 30-inch outside diameter pipe column. The foundation has a detachable beam allowing a 90-degree opening to capture the pipe column. Split reactor ring halves fit around the captured pipe and are locked together with high steel pins.
For smaller pipe sizes, the split insert ring halves slip inside the split reactor ring assembly, lift the reactor ring assembly up to one foot, and apply the desired pipe tension as adjusted by the operator at the HPU control panel. The cylinders can be locked in the extended position with local isolation valves hidden below the beam surface. The unit is plumbed with all stainless steel tubing which runs below the beam surface and is protected by stainless steel sheet covers. All components are painted with a protective a three-part offshore coating system.
