Features of PU layflat Fire Hose
For high-rise buildings, the facades of buildings are usually constructed with glass curtain walls, and it is difficult to lay fire hoses vertically. If an internal fire occurs, a fire hose must be laid along the stairs before fire fighting, which will affect the fire During the time of firefighting, OrientPU fire hoses have metal joints on both ends during use. You can connect another hose to extend the distance or connect the nozzle to increase the liquid spray pressure.
Fire hose are hoses used to transport flame-resistant liquids, such as high-pressure water or foam. Traditional fire resistant ribbon lined with rubber and linen woven fabrics. Advanced fire hoses are made of polyurethane and other polymer materials. There is a metal discussion in the middle of the fire hose, and another hose can be connected to extend the interval or to the nozzle to increase the liquid radiation pressure.
The characteristics of PU layflat fire hose are as follows:
1. The fabric layer of the fire hose should be evenly woven with a neat appearance without double warp, double warp breakage, weft jump and scratches.
2. Fire hose lining (or cover layer) has uniform thickness, smooth appearance and no defects such as wrinkles. 3. The nominal size of fire hoses and the inside diameter of public utilities must comply with the rules.
4. The length and size of fire hoses should comply with public service rules.
5. The planned task pressure and pressure resistance of fire hoses shall not be lower than the specified values.
Fire hoses are hoses used to transport water in a fire. According to the material, it can be divided into lined fire hose and non-lined fire hose. Among them, the unlined fire hose has the characteristics of low pressure resistance, high resistance, easy leakage, mildew, and short life. It is suitable for laying in the field of building fire protection. ; The lining water hose has high pressure resistance, wear resistance, mildew resistance, good durability, not easy to leak, low resistance, and can be bent at will. Free to move and easy to use, it is suitable for laying and connecting fire trucks in the field.
