Fire Hoses (Layflat and Semi-Rigid)

-- Steady & Reliable Manufacturer --

Introduction: High-Pressure Water Conveyance

Fire hoses are the lifeline of a fire suppression system, responsible for conveying high volumes of pressurized water from the source (hydrant/pump) to the nozzle. We manufacture two primary types: Layflat Hoses (fully collapsible) used by brigades and industrial teams, and Semi-Rigid Hoses used in fixed hose reel installations. Both types are engineered for maximum durability, pressure handling, and abrasion resistance.

Our Layflat hoses feature an inner rubber lining (SBR/EPDM) encased in a high-tenacity polyester woven jacket, providing exceptional pressure ratings (up to 20 bar Working Pressure) while remaining lightweight and compact for storage. Our Semi-Rigid hoses (for reels) are made from high-quality PVC or rubber, ensuring they retain their shape for easy rolling and deployment. All hoses undergo rigorous internal pressure testing to guarantee burst resistance and compliance with standards like EN 14540 (Layflat) and EN 694 (Semi-Rigid).

We offer hoses in standard lengths (15m, 20m, 30m) and diameters (DN40, DN50, DN65), supplied either bare or factory-coupled with the client's chosen coupling standard (Storz, BS, etc.). Our commitment to superior quality control ensures every meter of hose can withstand the critical demands of emergency firefighting. (Approx. 550 words)

Advantage: Durability, High Pressure Rating, and Compactness

  • Extreme Burst Resistance: Our Layflat hoses are constructed with high-tenacity polyester warp and weft for exceptionally high burst pressure ratings, far exceeding standard requirements.
  • Abrasion and Chemical Resistance: Outer jackets can be supplied with polyurethane or special coatings, significantly extending life in tough industrial and chemical environments.
  • Seamless Linings: Inner rubber (EPDM/SBR) linings are smoothly extruded, minimizing flow friction loss and maximizing water delivery efficiency.
  • Factory Coupling Integrity: Hoses are coupled using professional wire-binding or crimping methods, guaranteeing a pressure seal that is stronger than manual banding.
  • Lightweight and Compact: Layflat hoses are designed to collapse completely flat, allowing for minimal storage space and fast, ergonomic deployment from racks or vehicles.
  • UV and Ozone Stability: Semi-rigid hoses for hose reels are formulated with UV stabilizers, ensuring they do not degrade when stored in sunlight or exposed areas.

Professional Usage Tips

  1. Layflat Drying:

    Layflat hoses should be thoroughly drained and dried after use before being rolled and stored. Storing wet canvas/polyester hoses can lead to mildew and degradation.

  2. Roll Inspection:

    When rolling Layflat hose, alternate the folding crease frequently to prevent wear and tear along the same stress point, prolonging the hose's working life.

  3. Semi-Rigid Rewinding:

    Ensure hose reel hoses are rewound tightly and evenly onto the reel after use or inspection to prevent kinking or permanent deformation.

  4. Avoid Sharp Edges:

    Never drag the hose (especially Layflat) over sharp concrete, glass, or rough edges when pressurized, as this significantly increases the risk of jacket abrasion and rupture.

  5. Coupling Compatibility:

    When ordering, always confirm the exact coupling thread (e.g., male NPT, female BS 336 Instantaneous) to ensure the hose is immediately ready for connection to existing infrastructure.

FAQ

Working Pressure (WP) is the maximum pressure at which the hose is designed to operate safely and continuously. Burst Pressure (BP) is the pressure at which the hose is designed to structurally fail, typically 3 times the WP for safety.

Modern Layflat hoses use synthetic materials (polyester/rubber lining) which are much lighter, highly resistant to rot/mildew, require less maintenance, and deliver better flow characteristics than older, heavy canvas types.

We offer both options. We can supply the hose as a bare roll or, more commonly, as a complete assembly, factory-coupled with your specified standard (Storz, BS, etc.) using professional crimping techniques.

DN65 refers to the Diameter Nominal 65mm, which is the internal diameter of the hose, corresponding to the coupling size it must connect to. This ensures flow rate consistency.

Yes, Layflat hoses can be woven using different colored polyester thread (e.g., yellow, blue, black) for specific applications or industrial color coding, subject to a higher MOQ.

Layflat hoses used by professional fire departments are typically required to undergo hydrostatic pressure testing every 5 years to verify the integrity of the jacket and lining.

The Semi-Rigid hose is designed to hold a circular shape even when unpressurized. This prevents kinking and ensures it can be deployed rapidly and efficiently from the hose reel, even when partially uncoiled.

Yes, the rubber linings (EPDM/SBR) and outer UV-stabilized PVC/polyester jackets are specifically formulated to resist cracking and degradation from exposure to ozone and strong sunlight over time.

We offer standard woven polyester, and for specialized high-abrasion environments, we can apply a durable Polyurethane (PU) coating or use a double-jacket weave for maximum resistance.

The MOQ for Layflat hose typically starts around 1,000 meters in total. You can mix diameters (DN50, DN65) and different lengths (15m, 30m) within that total meterage.
