What is a Fire Hose Pipe?
A fire hose pipe is a high-pressure, flexible conduit used by firefighters and trained personnel to transport water from a source to the site of a fire. The source can be a fire engine’s pump, a building’s standpipe system, or a fire hydrant. Designed to withstand extreme conditions, these hoses are built for durability, flexibility, and high-pressure capacity.
The primary function of a firefighter hose is to provide a controlled and powerful stream of water to extinguish flames from a safe distance. Its construction involves multiple layers of material, each serving a specific purpose, from resisting abrasion to preventing leaks under intense pressure.
Anatomy of a High-Quality Fire Fighting Hose Pipe
Understanding what goes into a fire hose pipe reveals why quality is so important. A typical hose is not a single piece of material but a composite structure designed for maximum strength and flexibility.
The Inner Lining
The innermost layer is a rubber or synthetic polymer lining. This layer is crucial for water-tightness. It must be smooth to minimize friction loss, allowing water to flow freely and maintain pressure over long distances. Materials like EPDM (ethylene propylene diene monomer) or thermoplastic polyurethane (TPU) are common choices due to their durability and resistance to chemicals and ozone.
The Reinforcement Jacket
Wrapped around the inner lining is a reinforcement layer, or “jacket.” This is the muscle of the hose, providing the strength to handle high water pressure without bursting. The jacket is typically woven from synthetic fibers like high-tenacity polyester or nylon.
- Single Jacket Hoses: These have one layer of woven fabric and are lighter, making them suitable for industrial or forestry applications where mobility is key.
- Double Jacket Hoses: These feature a second woven layer for extra durability and higher pressure resistance. A double jacket is the standard for most municipal fire departments, as it provides superior protection against cuts, punctures, and abrasion—common hazards in a structural fire.
At Rubber Hose India, we specialize in manufacturing robust hoses with tightly woven jackets that ensure maximum durability and a long service life.
The Outer Coating
Some fire hoses, particularly those used in industrial or chemical environments, have an additional outer coating made of rubber or nitrile. This layer provides an extra shield against chemicals, oil, UV radiation, and physical damage. It also makes the hose easier to clean and maintain.
Exploring the Main Fire Hose Types
Not all fires are the same, and neither are fire hoses. Different situations call for different tools. The main type of fire hose pipe can be categorized by its intended use.
1. Attack Hose
An attack hose is what most people picture when they think of a firefighter hose. This is the primary hose used to actively fight the fire. It needs to be flexible, relatively lightweight, and capable of handling high pressure. Attack hoses typically range from 1.5 to 2.5 inches in diameter. They are designed to be maneuvered by firefighters inside buildings and around obstacles. The goal is to get water directly onto the flames, making maneuverability a top priority.
2. Supply Hose / Relay Hose
A supply hose, often called a Large Diameter Hose (LDH), serves a different purpose. Its job is to move large volumes of water from a pressurized source—like a fire hydrant hose connection or another pumper truck—to the attack engine. These hoses are much larger, with diameters ranging from 3 to 6 inches or more. They are designed for maximum water flow over longer distances rather than for maneuverability at the fire scene.
3. Suction Hose
A suction hose is a specialized, rigid hose used to draft water from an unpressurized source, such as a lake, pond, river, or portable water tank. Unlike attack and supply hoses, which operate under positive pressure, a suction hose must withstand negative pressure (a vacuum) without collapsing. They are essential for firefighting operations in rural areas where fire hydrants are not available.
4. Booster Hose
A booster hose is a smaller-diameter (typically 1-inch) rigid rubber hose often kept on a reel on the fire engine. It’s used for small outdoor fires, like car fires or trash fires, where a large volume of water isn’t necessary. It’s quick to deploy and rewind, making it perfect for rapid initial responses.
Proper Use and Maintenance: Ensuring Reliability
A fire fighting hose pipe is a life-saving device, and its reliability is non-negotiable. Proper care and regular maintenance are essential to ensure it functions correctly during an emergency.
- Regular Inspection: Hoses should be visually inspected after each use and on a routine schedule. Look for cuts, abrasions, burns, chemical damage, or any signs of wear and tear on the jacket and couplings.
- Thorough Cleaning: After use, every hose fire pipe should be cleaned. Dirt and grime can be abrasive and wear down the fibers of the jacket over time. If the hose was exposed to oil or chemicals, it needs to be decontaminated according to specific protocols.
- Proper Drying: One of the biggest threats to a fire hose is mildew, which can rot the fabric jacket. After washing, hoses must be dried completely before being stored. Modern hose towers or drying racks are used to hang hoses vertically, allowing water and moisture to drain away. Hoses with a rubber exterior can be wiped dry.
- Hydrostatic Testing: Fire departments perform annual hydrostatic tests on their hoses. This involves pressurizing the hose with water to a specific test pressure to ensure it can still safely handle its rated working pressure. Any hose that fails this test is immediately removed from service.
- Correct Storage: Hoses should be stored in a clean, dry, and well-ventilated area away from direct sunlight and extreme temperatures. They are typically rolled or folded in specific ways (like the “donut roll” or “accordion fold”) to be ready for quick deployment.

Frequently Asked Questions (FAQs)
Q1: What are fire hose pipes made of?
A fire hose pipe is constructed in layers. It typically has an inner waterproof lining made of rubber or a synthetic polymer like EPDM. The outer layer, or jacket, is a woven fabric made from strong synthetic fibers like polyester or nylon. Some hoses have an additional external rubber coating for extra protection.
Q2: How much pressure can a fire hose handle?
The pressure rating varies depending on the type of fire hose pipe. An attack hose is typically tested at pressures up to 400 psi (pounds per square inch) but operated at lower pressures. A supply hose operates at lower pressures, usually under 200 psi. Every hose is rated for a specific working pressure and burst pressure.
Q3: How do you connect a fire hose to a fire hydrant?
A fire hydrant hose connection is made using the couplings at the end of the hose. Firefighters use a specialized tool called a hydrant wrench to open the valve on the hydrant. The female coupling of the supply hose is then threaded onto the male outlet port of the hydrant. It’s crucial to ensure a tight connection to prevent leaks under pressure.
Q4: How long is a standard fire hose?
The standard length for a section of fire hose in the United States is 50 feet. Multiple sections can be connected using the couplings to reach the required distance for any firefighting operation.
Q5: Why is choosing a quality manufacturer important?
Choosing a reputable manufacturer like Rubber Hose India is critical because the performance of a fire hose pipe is a matter of safety. A high-quality hose ensures reliability under extreme pressure, resistance to punctures and abrasions, and a long service life.
