Hoses for abrasive products are used in one of the most demanding applications in fluid handling. In industries such as cement, mining, dredging, or powder tanker transport, internal wear can lead to premature failure, leaks, and unplanned downtime.
Unlike other materials, abrasive products do more than flow through a hose: they continually erode its inner surface. The rate of wear depends on several factors, including flow velocity, particle size, material density and the conveying method.
What makes a material abrasive?
- Particle size and shape: Angular particles cause greater wear.
- Flow velocity: Higher velocity increases erosion.
- Material density: Denser materials have a greater impact on the hose.
- Conveying method: Dilute phase conveying involves higher velocities, while dense phase conveying can produce greater impacts.
Abrasion is the main cause of failure
Common questions on site:
- Why do my hoses wear out so quickly? → Unsuitable hose selection, excessive velocity or impact points.
- What has the greatest effect? → Abrasion, more than pressure.
- Where do hoses fail? → At inlets, outlets, bends and connections.
- How can service life be extended? → By adjusting the installation, hose material and maintenance practices.
Demanding applications
- Cement and silo tankers: High velocity and continuous wear.
- Mining: Severe abrasion and impact.
- Dredging: Mixtures of solids and liquids that place heavy mechanical demands on hoses.
- Food processing: Abrasion combined with regulatory requirements.

Why couplings matter
In abrasive applications, the coupling is a critical point. A poor transition causes turbulence and impact, accelerating wear. Guillemin couplings are commonly used in this sector, and Storz couplings are also sometimes used
A smooth internal transition and correct assembly are essential.
The key: a complete solution for abrasive products
A common mistake is to assume that a more resistant hose will solve the problem on its own. Performance depends on several elements working together:
- The right hose
- Suitable couplings
- An optimised installation
- Preventive maintenance
