HEXAGON & TETRAGON HOSE
SARO wear-resistant flexible hoses for pneumatic transport
HEXAGON Hose and TETRAGON Hose are flexible anti-wear solutions developed by SARO for pneumatic conveying applications of highly abrasive materials, both for discharge and suction. These systems combine the flexibility of rubber hoses with the high wear resistance of SARCER ceramic, offering high performance even in the most severe operating conditions. In pneumatic conveying of bulk and powdery materials, flexible pipes are one of the points most subject to erosion and abrasion, especially in the presence of:
- increase transport speed
- change of direction
- Vibrations and dynamic movements
- Highly aggressive and abrasive materials
The HEXAGON & TETRAGON Hose solutions are designed to ensure:
- high resistance to erosion
- long operating life
- maintenance reduction
- business continuity
- Installation flexibility even in complex geometries
The applications concern in particular the pneumatic transport of:
- Dry cement
- coal dust
- Industrial ashes and dusts
- Solid Recovered Fuel (SRF/CDR)
- abrasive mineral materials
- products from waste/material recovery processes
These systems are used in:
- cement plants
- steel mills
- waste-to-energy plants
- Caves and mining facilities
- Waste/Material Recovery and Treatment Facilities
- Energy and process industries
HEXAGON & TETRAGON HOSE provide the following product features:
