Fire Hoses (Layflat & Semi-Rigid)
Fire hoses deliver water quickly and safely with abrasion- and pressure-resistant construction. With internal linings and reinforcement layers, they withstand high operating pressures. In fire hose reels you typically see semi-rigid hoses (25/33 mm), while hydrant lines commonly use layflat hoses (45/52/65 mm).
Selection Guide: The Right Hose for the Area
Choosing the correct diameter/length and lining is critical for flow, reach and durability.
| Area / Scenario | Recommended Hose | Diameter & Length | Note |
|---|---|---|---|
| Indoor fire hose reel | Semi-rigid (reel) | Ø25/33 mm • 20–30 m | Fast deployment, kink-resistant flow |
| Hydrant line / outdoor | Layflat | Ø45/52/65 mm • 20–30 m | High flow, lighter to carry |
| Chemical/oily environment | Layflat (NBR/PU lining) | Ø45–65 mm • 20–30 m | Improved oil/chemical resistance |
Technical Specifications & Standards
Values below are typical; they may vary by brand/model. Follow your system specification.
| Item | Layflat | Semi-Rigid | Notes |
|---|---|---|---|
| Diameters | Ø45 / 52 / 65 mm | Ø25 / 33 mm | Choose by flow and reach |
| Length | 20–30 m | 20–30 m | Depends on reel/line layout |
| Lining | EPDM / NBR / TPU | EPDM / NBR-PVC | Chemical & temperature resistance |
| Operating Pressure | 10–16 bar (typical) | 10–12 bar (typical) | Test/burst depend on manufacturer |
| Couplings | Storz / BS 336 etc. | Storz / Nipple | Must match hydrant/nozzle |
| Standard | TS EN 671-2 (system) | TS EN 671-1 (system) | Cabinet/reel system standards |
Maintenance & Periodic Checks
Regular inspection and proper storage are essential for effective response.
| Interval | Action | Description |
|---|---|---|
| Monthly (visual) | Cracks, kinks, coupling gasket | Check hose for flattening/cracks; gasket deformation |
| Every 6 months | Pressure & leakage | Nozzle flow and joint leakage test |
| After use | Dry & roll | Fully dry layflat hoses before folding to prevent mildew |
| Annually | Periodic test | Static/flow test at operating pressure; record results |
Frequently Asked Questions
Should I pick 25 mm or 33 mm? ▾
25 mm is common and lighter indoors; 33 mm provides higher flow. Decide based on line pressure and required reach.
EPDM vs. NBR/TPU lining? ▾
EPDM is balanced for general use. In areas with oil/chemical exposure, NBR or TPU linings are preferable.
