Brief description

A hose is a flexible hollow tube designed to carry fluids from one location to another. Unlike pipes, hoses are flexible and can be easily moved or coiled.

Use / Function

• Transport: Moving water, fuels, or gases.
• Gardening/Agriculture: Watering plants (garden hose).
• Firefighting: Delivering high-pressure water (fire hose).
• Diving: Supplying air to divers.
• Hydraulics: Transmitting power in machinery.

Operating principle

Hoses operate on the same principle as pipes, containing fluid pressure. Their flexibility comes from the materials used and their reinforcement structure (braiding).

How to create it

1. Extrusion: For plastic or rubber hoses, the material is pushed through a die to form a tube.
2. Reinforcement: A layer of braided fiber (nylon, wire) is wrapped around the inner tube.
3. Coating: An outer layer is applied for protection.
4. Traditional: Sewing strips of leather or canvas into a tube (early fire hoses).

Materials needed

• Inner tube: Rubber, Plastic (PVC, Polyurethane).
• Reinforcement: String, wire, or fabric mesh.
• Connectors: Metal or plastic fittings at the ends.

Variants and improvements

• Garden Hose: Standard PVC or rubber for water.
• Fire Hose: Canvas or synthetic fabric, collapsible and high-pressure resistant.
• Hydraulic Hose: Reinforced with steel wire for very high pressures.
• Soaker Hose: Porous material to let water seep out slowly.

Limits and risks

• Kinking: Sharp bends can block flow.
• Bursting: Exceeding pressure limits.
• Degradation: UV light and chemicals can crack the material.
