For heavy-duty use
The Trellex Hose System is the natural choice for hand-
ling materials in heavy-duty hydraulic or pneumatic
conveying systems.
The system is designed on the basis of fi rst-hand experi-
ence of transporting highly abrasive iron, copper and
other metallic or non-metallic ores in mineral processing
plants.
Rubber off ers superior wear resistance when handling abra-
sive rocks and sands, as well as slag and other materials.
The Trellex Hose System is used in sand, lime, and glass
plants, in quarries, in coal preparation and power plants,
as well as in steel and cement works.
Rubber absorbs energy
Rubber is an elastomer. While steel and ceramics present
a rigid surface to the particles, rubber has the advantage
of resilience.
The kinetic energy of the slurry generates deformations
and cracks on a rigid pipe.
In contrast, the Trellex Hose absorbs the load by yielding,
and then returning to its original form.
Vibrations from e.g. a pump are dampened.
Appropriate conditions
The angle at which particles strike a surface is decisive
for the process of wear. Both laboratory tests and practi-
cal experience show that rubber is more resistant than
other materials when impacting angle is less than 5°, or
greater than 50°.
In slurry lines, the angle of incidence is close to 0°. Process
water does not corrode rubber, but instead acts as a
lubricant, further decreasing erosion. Trellex Hose are
ideally suited for hydraulic transport of abrasive rocks
and sands as well as for use in loops in tailing lines to
compensate for thermal expansion and contraction of
steel pipes.

Trellex Hose System
Supplied in two types
Trellex Slurry Hose for hydraulic pressure and suction service
of abrasive slurries containing particles of up to 20 mm in
size, and Trellex Bulk Hose for pneumatic service of abrasive
powders and chips of up to 30 mm in size.
Trellex Slurry Hose and Trellex Bulk Hose are both reinforced
with polyester cord and a fully embedded spiral of galvanized
steel wire. The safety factor against bursting is 3.2 times the
working pressure. A smooth outer cover with a fabric texture
ensures good resistance to wear and weather.
Thick, smooth-walled wear tubes provide low resistance to
fl ow and extremely long life.
Together with the Trellex Coupling and the Trellex Gasket,
these hoses form a highly reliable system that retains full fl ow
area with no turbulence at the joints. Spot wear and leaks are
eliminated.
Utilizing the Trellex Hose System to its full potential will keep
your plant cleaner and further reduce costs by increasing mill
availability. Limiting the use to bends only will also limit
the extent to which the Trellex Hose System can work to your
advantage.
Trellex Slurry Hose for hydraulic applications has a NR wear
tube of Trellex 40 rubber. The hose withstands operating
temperatures of up to 60-70° C.
Trellex Bulk Hose for pneumatic applications has a SBR wear
tube of Trellex 60 rubber. The hose withstands operating
temperatures of up to 70-80° C.
Sizes Ø 44-127 mm are supplied in coiled lengths of 20 m.
Larger sizes in straight lengths of 10 m.
Both Trellex Slurry and Trellex Bulk Hose are available without
steel wire spiral, for gravity service only.

where the Trellex Hose cannot be suffi ciently curved, or e.g.
as feed spouts for magnetic separators or other similar equip-
ment. They are available both as 90° and 45° bends, and are
supplied in two types.

Trellex Hose System
The Trellex Split-Flange Coupling is designed for use with
Trellex Hoses and Bends. The coupling doesn´t not come in
contact with the material fl owing through the hose, and is thus
not exposed to wear. Its manufactured from high-strength
aluminium alloy.
The Trellex Coupling consists of two or four identical segments,
which are fi tted mechanically on the smooth hose. If a seg-
ment is lost or damaged, it can be replaced by any other seg-
ment of the same size. If a hose has to be replaced, the old
coupling is fi tted to the new hose.
The coupling does not have to fi t any specifi c pattern on the
hose cover. It is simply rotated around the hose until it is
aligned with the connecting fl ange. There is no need to rotate
the hose itself.
The coupling is designed for fast, simple fi tting.
Neither special tools or skilled personnel are needed. Each
coupling is delivered with bolts for the side fl anges, square-
headed to prevent them from turning.
No other bolts are provided.
The Trellex Split-Flange Coupling is compatible with all major
fl ange drilling standards.
Trellex Coupling
– Lower cost, thanks to modular design and reusable
coupling.
– Not exposed to wear, since the coupling doesn’t come
in contact with the transported material.
– Manufactured from high-strength aluminium alloy,
gives you low weight.
– Simple installation, No special tools needed.
– Compatible with all major fl ange drilling standards.

The tapered Trellex Gasket is designed for use with Trellex
Hoses and Bends. Together with the Trellex Coupling, this gas-
ket will give leak-proof, full bore joints.
The Trellex tapered gasket is reinforced with a steel insert,
which makes it stiff and allows it to be pushed inside the hose,
guided by the same inside bore that you want to match.
To complete one full joint between two hoses, two couplings
and two gaskets are required.
When tightened against the connecting fl ange, the inside
tube of the hose will be pressed up against the outside slope
of the gasket. The slurry itself will quickly wear the inside of
the gasket fl ush with the hose, leaving a full-bore transition,
free of turbulence.
It is the inner diameter of the hose that will correctly position
the gasket in the centre of the bore.
The taper of the gasket will further compensate for the une-
venness in the end of a hose when it is cut to exact length
onsite.
The ends of the hose do not have to be ground fl at as when
working with ordinary, fl at rubber gaskets.
The fl uting of the front of the gasket will eliminate any leakage.
Trellex Gasket
– Steel reinforced, to be able to receive the same inside
bore as the hose when pushed in to the hose.
– Full-bore transition, free of turbulence.
– Thick, smooth-walled wear tubes providing low
resistance to fl ow and long service life.
– The taper compensates for any unevenness at the
hose ends.
– Fluting pattern at the front eliminates leakage.
