A fire hose is a highly pressurized hose that is used to bring water to the fire. It may also transport flame retardants. Fire hoses can be attached to either a fire engine or a fire hydrant, and the pressure is between 800 and 2000 kPa.

Fire Hose feature: -

▶Description: PVC, EPDM, And Rubber.

▶Standard Length: 20-45 m.

▶Application: Large diameter hose for water supply, municipal, internal firefighting.

▶Color: Red as White hose.

▶Structure: 3 layers.

▶Working Pressure: 8 Bar.

▶Jacket: Single

▶Size: 1", 1-1/2", 2", 2-1/2", 3".

Fire Hose Inspection:

For reasons of fire safety, it's quite important to have a fire hose inspection as well as all fire protection equipment tested. If, during a fire emergency, the fire hose fails it could have disastrous results.

If a facility is equipped with a sprinkler system it's most likely going to have a fire hose and a standpipe system that is capable of dispensing water at high pressure. It's a requirement that the hose or hoses that go with that system be tested periodically.

Different Types of Fire Hose

Fire hoses come in various types, each designed for specific applications and environments. Here are some of the main types:

▶Attack Hose: Also known as a front line or supply hose, it’s used to directly combat fires. It is designed to be relatively light and flexible, allowing firefighters to maneuver it into position yet sturdy enough to withstand high pressures. They are typically smaller in diameter, around 1.5 to 3 inches.

▶Supply Hose: These are larger hoses, often ranging from 3.5 to 5 inches in diameter. Supply hoses move large volumes of water from hydrants or other water sources to the foreground or a fire engine’s pump.

▶Forestry Hose: Designed for fighting wildfires, forestry hoses are lightweight, flexible, and designed to be carried long distances over rough and uneven terrain. They usually have a smaller diameter and are made of materials that can withstand outdoor conditions.

▶Booster Hose: A booster hose is a rubber-covered, thick-walled, flexible hose to fight small fires. It retains its round cross-section when not under pressure and is usually carried on a reel on the fire pumper rather than being stored flat. Booster hose comes in 0.75 inches (19mm) and 1 inch (25mm) nominal inside diameters and is often used for mop-up at a fire scene to extinguish hot spots.

Suction Hoses: These connect a fire engine to a water source, such as a fire hydrant. They are made to withstand vacuum pressures so they don’t collapse when the pump draws water. Suction hoses are typically large in diameter, allowing more water to be drawn into the pump.

▶Relay and Supply Hoses: These are large-diameter hoses, usually 3.5 inches (89mm) or 5 inches (127mm), which are used to convey water over long distances, often from one hydrant to another or to a pumper located near the fire.

▶Occupant Use Hoses: These are found in cabinets in building hallways. They are typically 1.5 inches (38mm) in diameter and about 100 feet (30m) in length, intended for use by building occupants in the early stages of a fire.

What is Fire hose failure?

Failure of the fire hose may occur as a result of overheating of the hose. Overheating will result in the stiffness of the hose. The inner tube will harden and begin to crack because the plasticizers in the elastomer will break down or harden under high temperatures. In some cases, the cover may show signs of being dried out.

Waterproof Heat Detector
Fixed Temperature Waterproof Heat Detector, the detector uses a bi-metallic strip to sense temperature change, therefore consuming minimal standby current and providing high reliability.
The Detector is particularly suited to environments, which are exposed to high levels of condensation or are hosed down. The detector has a wide operating margin allowing it to respond to both slow and fast increases in temperature; it can also sense temperature reliably in a horizontal or vertical position.

Addressable Explosion-proof Fire Alarm System Introduction

Aug .08.2023

The Explosion Proof range of products has been designed to provide protection against explosions and products to ensure that all major advantages of high-quality fire detection technology can be safely exploited in industrial and hazardous environments. Many difficult sites such as metal, paint, pipelines, chemical, pharmaceutical, oil refineries, and other installations are vulnerable to the risk of explosion. In order to protect the assets and people, they need special solutions for fast and reliable fire detection.
