Application Of Polyurethane Remote Water Supply Hose in Mine Rescue

Polyurethane remote water supply hose is a kind of hose that can be flat-coiled for positive pressure delivery. Static electricity problem.

It can replace steel pipes and composite pipes in mine rescue. It has the advantages of light weight, high pressure bearing, high conveying efficiency, soft texture, coilable, convenient operation, fast laying and withdrawal speed, flexible maneuverability, strong environmental adaptability, and safe use. Reliable and durable and so on.

The joint also has the advantages of interchangeability, simple structure, convenient operation, quick assembly and disassembly, and reliable operation. When connecting, just dock the two quick connectors and rotate clockwise. The water supply hose with quick connector can greatly shorten the installation time of the drainage pipeline and win valuable time for mine drainage rescue.

The common diameter of this kind of hose is from Ф25mm to Ф300mm, the rated working pressure is 2.8MPa, and the bursting pressure can reach 8.4MPa. Considering factors such as the difficulty of pipeline installation and meeting the drainage requirements, the diameter of the selected pipeline should not be too large, preferably Ф150mm to Ф250mm. When the height difference of the roadway is less than 300m, all polyurethane high-pressure hoses are used. When the height difference is greater than 300m, seamless steel pipes are used for the part below the vertical depth of 300m, and polyurethane remote water supply hoses are used for the drainage pipelines above 300m.
