Firemen Sleeves. Properties And Application.

Modern conditions of human life require him to fulfill the requirements of certain norms, including fire safety rules. This is due to the size of the likely damage from various kinds of fires. And even more important is the rapid elimination of the source of fire. In turn, any fire can not be quickly and effectively eliminated, without organizing the supply of fire extinguishing agents to the fire site. To transport these funds, fire hoses are used.

These hoses serve as fire extinguishing means and are included in the set of necessary equipment for fire protection of public buildings, structures and even large and small ships.

Fire hoses are flexible pipelines, for connection of which special connecting heads are used.

To connect the fire hose to the hydrant, use special metal connecting heads, which can also be used to connect fire hoses with each other. In this case, each head is provided with a rubber gasket, which ensures reliable connection of fire hoses.

In accordance with the particular application, fire hoses (fire hoses) are divided into three types: pressure, suction and suction hoses.

Pumping of fire extinguishing agents in the sleeves is carried out due to excess pressure ( pressure fire hose), or due to vacuum (suction). A feature of suction hoses is their rigidity, and pressure hoses have sufficient flexibility and strength.

Pressure hoses are characterized by a flexible design and are intended for pumping pressure extinguishing agents under fire to the fire, which necessitates the presentation of special requirements for the materials used in the manufacture of hoses and their strength. Pressure hoses are made of heat-resistant synthetic threads, and the upper layer consists of vulcanized rubber. Sleeves are completed with couplings connecting the hose with other fire-technical equipment. The technology of production of pressure fire hoses provides a warranty period of operation for 10 years.

Suction fire hoses have a rigid structure of the textile frame, they are designed to take water from the source and feed it to the source of ignition. When using the hose, it is necessary to avoid contact with the ground to prevent mechanical damage.

Pressure-suction fire hoses have the qualities of both types of hoses.
