READ MORE1.Fire hoses are hoses used to transport high-pressure water or fire-retardant liquids such as foam. Traditional fire hoses are lined with rubber and wrapped in a braided linen outer surface. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or a nozzle to increase the liquid spray pressure.
2.Fire hoses basically consist of three parts: a braided layer (plain weave and twill weave) and a lining and outer covering (main materials used: rubber plastic, rubber and polyurethane); Type 13 and above are mainly made of polyurethane.
3.Product features: This water belt is resistant to high pressure, acid and alkali, and high temperature. The coating is smooth and has low resistance, high strength, light weight, soft and lightweight.
4.Scope of application: This hose is widely used in agriculture (such as water curtain hose), industry and fire protection; the hose can be made in red, green, orange, etc., and the color length can be customized according to customer needs.
1.Other high model hoses (can be made into 20 meters/25 meters/30 meters)
8-50 25-65 25-80 13-100
2.Other water belts (can be made into 20 meters/25 meters/30 meters)
Water curtain water tape, luminous water tape, double-sided adhesive tape and colorful water tape (common red, green, orange, purple, etc.).
3.Our factory can tie the water hose to the fire protection interface.

Fire hose and reel:
The reel is composed of valves, input pipelines, spokes, support frames, rocker arms, hoses and spray guns. It uses water as the fire extinguishing agent and can spray the fire extinguishing agent while rapidly unfolding the hose. Generally installed in an indoor fire hydrant box, it is a new type of indoor fixed fire protection device.
It is suitable for extinguishing fires caused by Class A carbohydrates such as paper, wood, cotton and linen fabrics; its fire extinguishing agent is water, a hose reel with a rated working pressure of 0.8MPa and a hose inner diameter of 19mm. For: JPS 0.8-19
The reels produced by our company are pressure-resistant and corrosion-resistant. The surface of the reel is treated with corrosion resistance, and the paint layer on the painted part is uniform.
Lightweight hose and reel:
Advantages of the lightweight hose reel: small size, light weight, simple operation, easy to use and not easy to leak, and will not affect use when encountering cold.
1. A fire connector is a connecting piece used to connect fire hoses or to fire hoses and fire hydrants. Types of card-type fire protection interfaces; added types of threaded fire protection interfaces
2.Fire protection interface types include: internal button interface, quick interface, pipe thread interface, internal thread fixed interface, external thread fixed interface, stuffy cover, reducing interface, etc. It is used between water belts and at the entrance and exit of fire hydrants, water guns, water distributors, water collectors and other equipment to transport water, water and foam mixture.

1. Fire water gun is a water jet tool for fire extinguishing. When it is connected with a water hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. According to different jet forms and characteristics, it can be divided into: DC water gun, spray water gun, multi-purpose water gun, etc. The commonly used water guns are direct flow and spray water guns.
2. Classification and model
>>According to the working pressure range, it is divided into:
①Low pressure water gun (0.2MPa-1.6MPa);
②Medium pressure water gun (>1.6MPa-2.5MPa)
③High pressure water gun (>2.5MPa-4.0MPa)
>>According to the form of fire extinguishing water sprayed by the water gun, it can be divided into:

Fire hydrant is a fixed fire-fighting facility. Its main function is to control combustible materials, isolate combustion-supporting materials, and eliminate sources of ignition. Divided into indoor fire hydrants and outdoor fire hydrants. Indoor fire hydrant is an indoor pipe network that supplies water to the fire scene. It has a valve interface and is a fixed indoor fire-fighting facility in factories, warehouses, high-rise buildings, public buildings and ships. It is usually installed in a fire hydrant box, together with fire hoses, water guns and other equipment. For use together.
Outdoor fire fighting is a water supply facility installed on the fire water supply network outside the building. It is mainly used for fire trucks to draw water from the municipal water supply network or outdoor fire water supply network to put out fires.
