Clamps for industrial suction PU flexible hoses

Clamps for PU flexible hoses for industrial suction networks

What is a flexible hose clamp?

After choosing your ducting, the question of how to secure it becomes central to guaranteeing the efficiency of your installation.

Mechanical operation of the worm-drive clamp (serflex type)

The worm screw engages on a toothed metal band. By turning the screw, the band slides and tightens the loop. This mechanical movement precisely reduces the diameter of the clamp.

The force is then applied in a circular manner, giving uniform pressure around the entire circumference of the hose.

The mechanism remains simple. A screwdriver is all that is needed for assembly.

Role in the airtightness of suction networks

The clamp ensures the junction between the flexible hose and the rigid machine sleeve. It compresses the ducting to seal every gap. This airtightness prevents parasitic air ingress. Without it, suction power drops drastically.
A hermetic connection secures your network. It also prevents any accidental disconnection during use.

Materials and durability in industrial environments

Galvanised steel is suitable for standard uses. For corrosive environments, we prefer stainless steel. This material withstands moisture and the chemical products commonly found in factories better.
A high-quality alloy withstands mechanical stresses. It prevents premature failure of the clamping mechanism under pressure.
Choosing the right material is paramount. It reduces your maintenance costs.

How to choose your clamps for flexible hoses?

Understanding the technical purpose is a good start, but it is now necessary to focus on the selection criteria to avoid choosing the wrong model.

Precise measurement of the outer diameter of the flexible hose

It is essential to measure the outer diameter, including the sheath, rather than the inner diameter. The reinforcement spirals often increase the total thickness by several millimetres, thus distorting your initial selection.
Consult our range of flexible hoses. Find the model compatible with your installation.

Selection of metal according to the working environment

We guide your choice according to the ambient humidity level. In standard woodworking, zinc-plated steel is sufficient. For the food industry or chemistry, stainless steel is mandatory as it withstands cleaning and acid vapours without rusting.
Materials to favour according to use:

  1. Galvanised steel for dry air
  2. 304 stainless steel for humidity
  3. 316 stainless steel for marine or chemical environments

Adaptation to the nature of the transported residues

It is necessary to analyse the impact of abrasive dusts such as sand or shavings. The clamp must firmly hold the ducting in place despite internal shocks and repeated vibrations in the network.
Thermal resistance is equally important. For the suction of hot fumes, the device must not loosen under the effect of heat in order to guarantee airtightness.
Versatility is key. A robust clamp absorbs stresses without ever coming loose.

Specific requirements according to your industrial applications

Beyond measurements, each trade imposes physical constraints that dictate the type of fixing to favour.

Needs of joinery workshops and wood industries

The massive management of shavings requires total reliability. The constant vibrations of woodworking machines can dislodge "low-end" fixings. We therefore recommend using robust models.
To guarantee network continuity, using a suitable flexible sleeve greatly facilitates the assembly of clamps.
The risk of fire is real. Perfect airtightness prevents the accumulation of explosive dusts in the workshop.

Constraints of metallurgy and chemistry

The suction of welding fumes exposes equipment to corrosive gases. A high-quality stainless steel clamp prevents premature failure of the device. This is an indispensable safety measure for operators working daily on these workstations.
Key advantages for your installations:

  1. Resistance to welding fumes
  2. Immunity to chemical corrosion
  3. Resistance to grinding projections

Protection of the spiral structure of the ducts

It is essential to prevent shearing. Over-tightening can cut through the PU or PVC between the metal spirals. It is therefore necessary to moderate manual force.
Choosing a quality PU flexible hose reduces the risk of perforation during pressurisation.

Installation and maintenance of your clamping points

Once the equipment is in hand, the quality of the final assembly will determine the longevity of your suction network.

Assembly steps for secure fixing

Always slide the clamp onto the flexible hose before fitting it onto the rigid connector. This simple method avoids unnecessary forced handling. We recommend preparing your segments carefully.
The clamp should be positioned approximately one centimetre from the edge of the ducting. This guarantees optimal grip of the device.
Check the alignment carefully. A band fitted at an angle may slip during negative pressure operation.

Recommended tools and tightening precautions

A flat-head screwdriver or a 7 mm spanner will do the job. Avoid overpowered electric screwdrivers that could strip the thread. Manual tightening allows you to better feel the resistance of the material.

  1. Spanner for controlled torque
  2. Screwdriver for small diameters
  3. No impact wrench

Preventive maintenance and leak detection

Over time, pressure cycles and vibrations can cause the metal to loosen. Regular visual inspections are necessary. An annual check is generally sufficient.
Identify signs of fatigue. Traces of dust around the clamp often indicate a micro air leak.
Act quickly. Re-tightening a clamp takes ten seconds and saves your suction flow.

FAQ

What is a serflex-type clamp for flexible hoses?

The flexible hose clamp, often called a "serflex", is an essential mechanical fastening device. Its role is to firmly secure the suction flexible hose onto a rigid sleeve in order to prevent any accidental disconnection during the use of your machines.
Generally made of metal, it incorporates a worm screw which, when tightened, exerts perfectly uniform pressure around the entire circumference of the hose. This action guarantees reliable airtightness and optimal mechanical resistance against industrial suction forces.

What diameters are available for your clamping collars?

To meet the majority of suction system configurations, we offer a wide range of sizes. Our clamps are available in diameters ranging from 80 mm to 300 mm, thus covering the standard needs of workshops and industries.
This variety allows the device to be precisely adapted to the size of your flexible hose and the associated sleeve. It is important to choose a model whose clamping range corresponds to the outer diameter of your ducting to ensure secure holding.

How to correctly install a clamp on a suction hose?

Installation is simple and quick. We advise you to first slide the clamp onto the flexible hose before fitting the latter onto the machine sleeve. Once the hose is correctly positioned, move the clamp to approximately one centimetre from the edge of the ducting for maximum grip.
Final tightening is carried out using a screwdriver or a spanner, depending on the type of screw on the housing. By turning the screw, the metal band tightens and compresses the flexible hose against the connector, thus creating a perfectly airtight and robust connection.

Which material to choose between galvanised steel and stainless steel?

The choice depends directly on your working environment. Galvanised or zinc-plated steel is an economical and robust solution for dry environments, such as standard woodworking workshops. It offers sufficient protection against moderate corrosion.
For demanding environments, such as the food industry, chemistry, or the suction of corrosive fumes, we recommend using stainless steel (304 or 316). Stainless steel guarantees superior durability and total immunity against moisture and aggressive products.

Can these clamps be used for applications other than suction?

Absolutely, the versatility of the worm-drive mechanism allows for many uses. In addition to industrial suction systems and machine tools, these clamps are perfectly suitable for connecting water pipes, gas pipes, or for ventilation and air conditioning systems.
Their robustness and ease of use make them a preferred fastening solution in the automotive, agricultural, and general industrial maintenance sectors. Simply select the diameter and material suited to the nature of the fluid or residue being transported.
