Denialink - Rubber Dredge Hose Discharge Application, Floating and Non-Floating

Denialink - Rubber Dredge Hose Discharge Application, Floating and Non-Floating.
 

Denialink offers, new made and second hand, flexible rubber dredge hoses.
These dredge hoses are available in floating and non-floating series, with internal diameters (IDs) of 1200 mm for the new made ones and up to ID 600 mm for the second hand ones.

The new made dredge discharge flexible dredge hoses.
Rubber dredge hoses are purpose built to the special requirements of our clients.
We are in the position to build dredge hose sizes ranging from 100 mm ID to 2200 mm ID.
Our designers will select the most appropriate materials from a wide range of products available to us to meet service and demands requested by our clients i.e. in regard to wear resistance, pressure ratings, tensile strength, bending capabilities and so on.

In general the Rubber Dredge Hoses consist out of an inner lining adjusted to the specific requirement of transported media.
Wear indicator layers can be implemented in the dredge hoses which transport abrasive media.
A textile reinforcement of high tensile strength will control the pressure resistance of the dredge hose as well as the tensile strength.
Where as the outer cover is built up by a rubber compound highly resistant against weathering, UV lights and Ozone.
On special request the outer cover can be built with oil resistant materials.

Dredge hose end fittings are available in a wide variety which are selected on duty requirements.
Discharge Dredge Hoses
Suction Dredge Hoses
Floating Dredge Hoses
Pre-Shaped Dredge Hoses
Armoured Dredge Hoses

The Second Hand Dredge Discharge Rubber Flexible Hoses
Denialink supplies a wide range of used (second hand) floating and submarine (non-float) rubber flexible hoses. The size of the internal diameters (ID) ranges from 24” (600 mm), 20” (500 mm), 16” (400 mm), 12” (300 mm), 10” (250 mm), 8” (200 mm) to 6” (150 mm). Other diameters and special requirements can also be supplied upon request and availability.

These hoses proceed mainly from the oil industry and are manufactured under the strict requirements of the Oil Companies International Marine Hose Guide (OCIMF). Manufacturers like Dunlop, Trelleborg, Bridgestone, Manulli,, Good Year, Yokohama, and Emstec all manufacture their hoses with slight variations, but all according to the OCIMF guidelines.

Technical information given is of new build status.
