Tensioner pad lining (v-shaped)
Tensioners are essential for installation and recovering pipelines, cables and umbilicals. These machines maintain a constant tension on the pipe when installing it into or retrieving it from the seabed or the ground. To maintain the tension, the pipe is clamped between traction pads. Ridderflex covers these track pads with polyurethane to prevent damage on the pipe.
In offshore applications, tensioners are essential onboard of pipe and cable laying vessels. During pipe laying operations, the tension on the pipe or cable has to be maintained at all sea conditions. The tensioner consists of a number of (caterpillar) tracks mounted in a frame. To maintain the tension, the pipe or cable is clamped between these v-shaped traction pads.
Polyurethane lining for tensioner pads
Ridderflex covers v-shaped tensioner pads with a polyurethane layer to prevent damage on the outer surface of the pipes and cables. Also, a safe and better grip is ensured. We produce these polyurethane linings in different thicknesses, hardnesses and colours.
|Thickness||Custom-made. Thickness of polyurethane lining between 10 mm to 300 mm.|
|Hardness||Standard 85 Shore A.
If required, hardnesses from:
20 Shore A to 95 Shore A
45 Shore D to 83 Shore D
|Colour||Various colours available.|
