Stinger rolls: pipe support rollers

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.

Polyurethane linings for pipe support rollers (stinger rolls)

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.

Hardnesses60 Shore A to 95 Shore A
ColoursVarious colours available
Epoxy layerThe part of the steel surface of the rollers that is not covered with polyurethane can be coated with a special seawater resistant epoxy layer.
