QINGDAO EASTOP PLASTIC PRODUCT CO., LTD.
We are a professional manufacturer and exporter of PVC hose.
Fire hose used to transport high-pressure water or foam and other flame-retardant liquids. The traditional fire hose is lined with rubber, and the outer surface is wrapped with flax braid. High-quality fire hoses are made of polymer materials such as polyurethane. There are metal joints on both ends of the fire hose. You can connect another rubber hose, polyurethane hose, or PVC fire hose to extend the distance or connect a nozzle to increase the liquid spray pressure.
The fabric layer of the hose should be woven evenly, and the surface should be neat; no double warp, broken double warp, weft jump or scratches.
The thickness of the hose lining (or covering layer) should be uniform, and the surface should be smooth and flat, without wrinkles or other defects.
Fire hose connection: When the fire hose is put on the hose interface, it must be covered with a soft protective object, and then tied with galvanized iron wire or hose clamp.
Fire hose use: When using a fire hose, the high-pressure-resistant hose should be connected to a strong place away from the water pump. The filled hose should be prevented from twisting or sudden bending, and the hose interface should be prevented from collision and damage.
Fire hose laying: When laying the hose, avoid sharp objects and various oils. When laying the hose vertically to a high place, use the hose hook. When laying the hose through the main traffic, the bridge should be protected by a hose , When passing the railway, the hose should pass under the track to prevent the hose from being crushed by wheels and intermittent water supply.
Fire hose cleaning: After the hose is used, it needs to be cleaned. For the foam-carrying hose, the protective rubber layer must be carefully scrubbed. In order to remove the grease on the hose, it can be washed with warm water or soap. For the frozen hose, first melt it and then wash and dry. The hose that has not been dried should not be stored in a roll.
