Overview

The armored floating hose combines the two things a long overwater line usually has to choose between: integral buoyancy and an armored lining. It is installed on the main discharge pipeline of a dredger for overwater slurry runs, built from an inner lining, reinforcement layer, buoyant interlayer, outer cover and carbon steel flanges, and carries mixed media such as water, silt, clay and sand while staying on the surface empty or loaded.

Who it is for

Contractors running long overwater discharge lines in abrasive material who are replacing floating sections more often than the rest of the line.

Key benefits

Buoyant interlayer keeps the hose afloat empty or in working condition
Highly wear-resistant natural rubber for demanding dredging conditions
Inner high-strength steel rings absorb pump vibration and pulsating pressure
High pressure resistance combined with flexibility and tensile strength
Stable floating performance maintained throughout operation

Problems it solves

What goes wrong without it

1

An abrasive overwater line either wears out fast or needs pontoon support; integral buoyancy plus a hard-wearing lining avoids picking one problem over the other.

2

Recovering and re-floating a sunken empty line at every shift change is lost production.

3

Pump pulsation across a long floating line fatigues the flange joints. The inner high-strength steel rings absorb it before it reaches them.

Construction and technical features

Construction: inner lining, reinforcement layer, buoyant interlayer, outer cover layer
Carbon steel flanges at both ends
Abrasion resistance, vibration absorption and aging resistance
Flexible body with flanged ends for easy handling during operation
Carries water, silt, clay and sand mixtures

Quality control

Raw material test on every batch of natural rubber, tensile textile and rubber additives before it enters the warehouse
Hose dimension check on inner diameter, outer diameter, wall thickness and flange alignment against the design drawing
Weight check on every hose to confirm it falls inside the agreed tolerance band
Hydrostatic or vacuum pressure test to the specified working pressure when the order calls for it
Third-party inspection can be arranged on request

Where it is used

Overwater main discharge line on a dredger working coarse material
Long floating runs where section replacement at sea is expensive
Port deepening works where the spoil is more abrasive than clean sand
Reclamation lines that stay in the water across multiple project phases

Customisation

Inner diameter 200-1100 mm in 5800 or 11800 mm lengths
Working pressure within the 0.5-4.2 MPa band
Flange drilling to your existing line standard
Customer branding and section identification in the marking

How it compares

Against the standard floating rubber hose, the armored version is specified when the conveyed material is wearing the lining faster than the buoyant structure is ageing. Against the armored discharge hose, this one floats by itself and needs no PE floats or pontoons on the overwater run.

Selection and use notes

Specify the dredged material and particle size, not only the diameter, when requesting a quotation
Protect the outer cover during lifting, since the buoyant interlayer sits behind it
Keep the line within its rated bend radius when repositioning
Rotate sections through the line so wear is distributed

FAQ

Questions buyers ask

How is this different from the standard floating rubber hose?

Both use the same buoyant interlayer construction and the same dimensional and pressure ratings. The armored version is built for more abrasive service.

Does it float when empty?

Yes. The buoyant interlayer keeps it afloat in both empty and working condition.

What are the available sizes?

Inner diameter 200-1100 mm, section length 5800 mm or 11800 mm.

What pressure is it rated to?

0.5-4.2 MPa working pressure and 1.5-12.6 MPa burst pressure.

What does it connect to?

It connects with CSD and TSHD dredgers to transport mud, sand, water and other mixed media.

Can inspection be witnessed by a third party?

Yes. A third-party inspection agency can be invited according to your requirements.
