HEXAGON & TETRAGON HOSE

SARO wear-resistant flexible hoses for pneumatic conveying

HEXAGON Hose and TETRAGON Hose are flexible anti-wear solutions developed by SARO for the pneumatic conveying of highly abrasive materials, both in pressure and suction lines. These systems combine the flexibility of rubber hoses with the high wear resistance of SARCER ceramic, delivering high performance even in the most severe operating conditions. In the pneumatic conveying of bulk and powdery materials, flexible hoses are among the points most exposed to erosion and abrasion, especially in the presence of:

  • high conveying speeds
  • changes of direction
  • vibrations and dynamic movements
  • highly aggressive and abrasive materials

The HEXAGON & TETRAGON Hose solutions are designed to ensure:

  • high erosion resistance
  • long service life
  • reduced maintenance
  • continuous operation
  • installation flexibility even in complex geometries

Applications include in particular the pneumatic conveying of:

  • dry cement
  • pulverised coal
  • ash and industrial powders
  • solid recovered fuels (SRF/RDF)
  • abrasive mineral materials
  • products from waste/material recovery processes

These systems are used in:

  • cement plants
  • steelworks
  • waste-to-energy plants
  • quarries and mining plants
  • waste/material recovery and treatment plants
  • energy and process industries

HEXAGON Hose

HEXAGON Hose is the high-performance standard solution developed by SARO for the pneumatic conveying of highly abrasive materials.

The structure combines:

  • the flexibility of technical rubber
  • a wear-resistant inner lining in SARCER ceramic
  • high resistance to continuous erosion and abrasion

HEXAGON Hose is designed for:

  • significantly reduce maintenance problems
  • extend the service life of pneumatic lines
  • ensure operating continuity even in severe conditions
  • maintain high conveying performance over time

TETRAGON Hose

TETRAGON Hose was developed for applications requiring greater operational flexibility while maintaining the same wear resistance as the HEXAGON Hose line.

The system configuration allows:

  • greater adaptability to plant movements
  • better vibration management
  • high resistance to wear and erosion
  • excellent performance in highly aggressive pneumatic conveying

TETRAGON Hose is mainly used:

  • in steelworks
  • in pulverised coal conveying systems
  • in pneumatic lines subject to movement and dynamic stress

Configurations and customisation

HEXAGON & TETRAGON Hoses can be supplied in different configurations:

  • smooth surface
  • corrugated version
  • glass-fibre fabric covering
  • corrugated configurations with fibre reinforcement

The hoses can also be:

  • fitted with different connection systems
  • supplied cut to size according to customer specifications
  • produced with special compounds for high temperatures or chemically aggressive environments

Standard availability:

  • 20 m from DN20 to DN63.5
  • 10 m from DN70 to DN100
  • 6 m above DN100

HEXAGON & TETRAGON Hose solutions are designed taking into account:

  • abrasiveness of the conveyed material
  • pneumatic conveying speed and pressure
  • operating temperature
  • plant configuration
  • dynamic and vibration conditions
  • required operating continuity

The goal is:

  • protect pneumatic conveying lines subject to heavy erosion
