Spring band clamps for hose-socket connections
Spring band clamps are used in particular in the following sectors:
- fluid systems
- engine construction
- hose systems
- commercial kitchens/Industrial dishwashers
- industrial air conditioners
- agricultural machinery
- floor cleaning machines
- campers
- heat pumps
- heating/air conditioning
- sanitary (e.g., toilets for ships, trains, aircrafts)
- food industry (e.g., bakery/coffee machines)
- solar thermics
- printing industry
- white goods
- construction machinery
- LPG installations
- compressors
- industrial trucks
- beverage industry (e.g. bottling plants)
Advantages of spring band clamps for connecting hoses with nozzles:
- high flexibility through continuous adaptation to changing characteristics, e.g. temperature fluctuations of the fasteners
- constant, uniform clamping force
- easy installation
- no subsequent tightening necessary
- high reusability, since spring force is not lost
- high process reliability due to the leak-free hose-connection
Types of spring band clamps
Material
- high-strength, alloyed spring steel 51CrV4
- high level of protection against brittle fracture, especially at low temperatures
Surface
- multi-layered & environmentally friendly chrome (VI) -free coating
- zinc-containing, inorganic basecoat and organic topcoat
- complies with the regulations of the automobile regulation (RoHS compliant)
Corrosion protection
- excellent resistance to corrosion, temperature (up to 210 °C) and chemicals
- guaranteed 720h salt spray resistance according to DIN EN ISO 9227
Available nominal diameter & bandwiths
- nominal diameter 9.0 mm to 90 mm
- bandwiths 8.4 mm, 10 mm & 12 mm
Pressure
- depending on the hose-socket combination, connections of up to a maximum of 11 bar can be fastened
Standardisation
- DIN 3021 Hose clamps - spring band clamps
- DIN 3021-1 Dimensions, designation, materials and design
- DIN 3021-2 Technical delivery conditions
- DIN 3021-3 System spring band clamp - hose - socket
| Hose clamps | |
|---|---|
| Pro | Contra |
| Wide diameter range | Rigid system |
| Cost-effective production with large diameters | High maintenance |
| High hose pulling forces | Expensive (with small diameters) |
| Time-consuming and expensive installation tool: torque and closing speed must be controlled | |
| Risk of injury due to protruding band | |
| Ear hose clamp | |
|---|---|
| Pro | Contra |
| Corrosion-resistant base material | Possible hose damage |
| Small clamp width | Not reusable (destructive dismantling) |
| Low space requirements | Special pliers necessary for installation |
| High hose pulling forces | High force required for installation |
| Cost-effective, very rigid fastener | Very small working range (strongly linked to diameter) |
| The force of the clamp depends on the pressing force of the assembly tool (complex controls required) | |
| Spring band clamps | |
|---|---|
| Pro | Contra |
| Highly flexible | Linked to diameter |
| Simple installation even on hard-to-reach connections | Comparatively high demands on the hose/support system |
| Very even surface pressure (distribution of radial force) | Hose/support/system must be taken into account |
| Adhesion to the hose possible in pre-opened condition | |
| Protects the hose | |
| Cost-effective | |
| Reusable | |
