Overview

Jetting water hose is the opposite duty to a discharge hose. It carries water, seawater or water with a small amount of sediment, so abrasion is comparatively light, but it runs at high pressure and has to stay flexible and dimensionally stable while doing it. It is fitted on trailing suction hopper dredgers at drag heads, drag arms and flushing pipelines, and is also used on long-distance water delivery lines.

Who it is for

TSHD operators and dredger builders specifying the jetting and flushing side, where pressure rating rather than abrasion drives the selection.

Key benefits

Engineered for high-pressure working conditions with structural integrity under continuous pressure
Special polymer formulation balances flexibility, ductility and stiffness
Modular structure for quick integration into existing dredging equipment
Suits both drag head jetting and long-distance water delivery
Steel flanges at both ends for secure, repeatable connection

Problems it solves

What goes wrong without it

1

A hose specified by diameter alone usually fails on the jetting line, because the governing requirement there is pressure rating rather than wear resistance.

2

Drag head jetting needs a hose that bends with the arm but does not balloon or kink under continuous pressure.

3

Integrating a new jetting run into an existing flushing system is slow when sections are not built as bolt-on modules.

Construction and technical features

Designed for water, seawater or water with small amounts of sediment
High pressure rating with maintained flexibility and ductility
Sufficient rigidity to resist deformation under working pressure
Modular section design for fast system integration
Q235 carbon steel flanges

Quality control

Raw material inspection on incoming rubber compounds and reinforcement
Dimensional check on inner diameter, wall thickness and flange alignment
Pressure testing to the specified working pressure
Third-party inspection can be arranged on request

Where it is used

Drag head jetting on a trailing suction hopper dredger
Drag arm flushing pipework
Deck flushing systems on dredging vessels
Long-distance water delivery pipelines

Customisation

Inner diameter 100-400 mm, length 1000-6000 mm
Working pressure specified within the 0.5-2.5 MPa band
Flange drilling matched to the existing jetting system
Modular section lengths to suit the drag arm layout

How it compares

Do not fit a discharge hose on the jetting line. Discharge hose is built around abrasion resistance for slurry; jetting hose is built around pressure capability for clean or nearly clean water, and is a smaller diameter range at 100-400 mm rather than up to 1100 mm.

Selection and use notes

Check the jetting pump's working pressure against the 0.5-2.5 MPa band before ordering
Route the hose so the drag arm's movement does not exceed its bend range
Use the modular section lengths to avoid field-fabricated joints
Inspect flange faces for erosion where sediment is present in the water
