Trellex Hose System

Rubber off ers superior wear resistance when handling abrasiverocks and sands, as well as slag and other materials.The Trellex Hose System is used in sand, lime, and glassplants, in quarries, in coal preparation and power plants,as well as in steel and cement works.Rubber absorbs energyRubber is an elastomer. While steel and ceramics presenta rigid surface to the particles, rubber has the advantageof resilience.The kinetic energy of the slurry generates deformationsand 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 conditionsThe angle at which particles strike a surface is decisivefor the process of wear. Both laboratory tests and practicalexperience show that rubber is more resistant thanother materials when impacting angle is less than 5�, orgreater than 50�.In slurry lines, the angle of incidence is close to 0�. Processwater does not corrode rubber, but instead acts as alubricant, further decreasing erosion. Trellex Hose areideally suited for hydraulic transport of abrasive rocksand sands as well as for use in loops in tailing lines tocompensate for thermal expansion and contraction ofsteel pipes.Supplied in two typesTrellex Slurry Hose for hydraulic pressure and suction serviceof abrasive slurries containing particles of up to 20 mm insize, and Trellex Bulk Hose for pneumatic service of abrasivepowders and chips of up to 30 mm in size.Trellex Slurry Hose and Trellex Bulk Hose are both reinforcedwith polyester cord and a fully embedded spiral of galvanizedsteel wire. The safety factor against bursting is 3.2 times theworking pressure. A smooth outer cover with a fabric textureensures good resistance to wear and weather.Thick, smooth-walled wear tubes provide low resistance tofl 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 owarea with no turbulence at the joints. Spot wear and leaks areeliminated.Utilizing the Trellex Hose System to its full potential will keepyour plant cleaner and further reduce costs by increasing millavailability. Limiting the use to bends only will also limitthe extent to which the Trellex Hose System can work to youradvantage.Trellex Slurry Hose for hydraulic applications has a NR weartube of Trellex 40 rubber. The hose withstands operatingtemperatures of up to 60-70� C.Trellex Bulk Hose for pneumatic applications has a SBR weartube of Trellex 60 rubber. The hose withstands operatingtemperatures of up to 70-80� C.Sizes � 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 withoutsteel wire spiral, for gravity service only.
