RAAH SAFETY - A stinger is essential for installation of pipelines, cables and umbilicals and is installed at the stern of a vessel. Onboard the vessel, pipe parts are welded together. The pipe is placed on the stinger and rolls over the pipe support rollers into the water. Ridderflex covers these rollers with polyurethane to prevent damage on the pipe.
The seagoing pipe is supported by the stinger. This way the radius can be controlled when the welded pipe bends towards the seabed during the installation phase.
Ridderflex covers stinger rolls with a polyurethane layer to prevent damage on the outer surface of the pipes and cables. We produce these polyurethane linings in different thicknesses, hardnesses and colours.
60 Shore A to 95 Shore A
Various colours available
The part of the steel surface of the rollers that is not covered with polyurethane can be coated with a special seawater resistant epoxy layer.
Our lining for pipe support rollers has the following properties:
Raah Safety supplies customised linings for pipe support rollers. We can help you to determine the required thickness of the polyurethane lining, as well as the hardness.
