Application of polyurethane high-pressure hose in mine rescue

During the production process of coal mines, there may be water leakage accidents that affect the lives of many miners. When a water leakage accident occurs, it is necessary to timely discharge the underground water. At this time, drainage pipes are needed, such as steel pipes, hard PE pipes, hydraulic pipes, etc. These pipes have their own advantages, some are cheap, some have high pressure resistance, and some have strong corrosion resistance. But they all lack an important advantage, which is speed!
Traditional mine drainage pipes, PE pipes, steel pipes, etc
The polyurethane high-pressure hose used in mining solves this problem very well. The polyurethane hose is made of flexible materials through high-temperature composite, which has good compressive performance. At the same time, it can also be flattened and rolled up, which is convenient for transportation and can withstand high working pressure. Combined with a high lift water pump, it can discharge the accumulated water from the deep underground of the coal mine.
The length of a roll of polyurethane hose can be very long, and in mining rescue, the length of each roll can generally reach 50 meters. This is not the limit length of polyurethane hose, but meets the actual needs of mining rescue, ensuring that it can be quickly transported to the underground and has sufficient length. Each roll of hose is equipped with a quick interface at both ends, which is a hose quick interface specifically used for mine rescue. It can quickly connect the two hoses together and also ensure no leakage or slipping during high-pressure water transportation.
At present, many places in China are beginning to attach importance to this aspect, and many units are gradually choosing high-pressure polyurethane hoses as important components for mine rescue. When purchasing polyurethane hoses for mining purposes, it is necessary to go to a reputable manufacturer and provide a national level third-party pressure testing report for the corresponding product. You need to understand the detailed parameters and past performance of the manufacturer's corresponding product, so that you can purchase products with confidence.
