Fire-resistant soft hose made of PU material
The PU fire hose is a lightweight and high-performance flexible hose specially designed for transporting water or fire-fighting foam. Its most notable feature is that it is made of polyurethane (PU) material, achieving an excellent balance between durability, flexibility and lightness.
What Is a PU Fire Hose?
The PU fire hose is not just a simple plastic pipe; it is a sophisticated product with a "sandwich" structure, designed to ensure its reliable operation under high pressure:
Inner lining: The innermost layer is usually a smooth synthetic material, such as ethylene propylene diene monomer (EPDM) or a specially formulated polyurethane (PU), ensuring smooth water flow and no leakage.
Reinforcement layer: The middle layer is a framework made of high-strength synthetic polyester yarns. This is the key to the hose's pressure-bearing capacity, locking the pressure firmly like a fishing net.
Outer protective layer: The outermost layer is the PU coating mentioned earlier, which provides wear resistance and aging protection for the entire hose.
Key Features of PU Fire Hoses
The ultimate lightness and flexibility: Compared with traditional rubber or linen fire hoses, PU hoses are much lighter. This enables firefighters to lay and retrieve the hoses more quickly in the fire scene, significantly saving their physical strength and securing precious rescue time.
Superior wear resistance and durability: PU materials are renowned for their "wear resistance". When used in fire hoses, their outer layer usually has an even more durable PU coating, which can withstand dragging on rough surfaces and scratches from sharp objects. Even in harsh environments, they are less prone to damage and have a longer service life.
Excellent weather resistance and chemical resistance:It can withstand ultraviolet rays, ozone and seawater corrosion. Its performance remains stable whether exposed to intense sunlight or in a humid environment. Additionally, it has excellent oil resistance and chemical resistance, and will not be damaged even if it gets contaminated with fuel or chemicals.
Efficient water delivery performance: The inner wall of the hose is extremely smooth, resulting in almost no resistance to water flow. This means that under the same pressure, it can transport more water, effectively reducing pressure loss and ensuring that the fire extinguishing agent can be forcefully sprayed towards the fire source.
Cautionary Notes
Avoid sharp objects: Although they are durable, they still need to be avoided from prolonged and intense friction against very sharp edges.
Pay attention to temperature: Although the PU hose has a wide temperature tolerance range (typically from -30°C to +80°C), it should be kept away from extreme open flames or high-temperature heat sources.
Regular inspection: Just like all fire-fighting equipment, it is necessary to conduct regular checks for any signs of wear, aging or leakage, and perform pressure tests in accordance with standards.
