Steel frame composite pipe mining pipe

Steel skeleton composite pipe mining pipe

The steel mesh skeleton polyethylene liquid pipe for underground coal mines is a new type of mining pipe. Its main features include:

Structure: This product has a steel mesh frame covered with polyethylene material. The steel mesh skeleton improves its strength and pressure resistance, while the polyethylene material protects the pipe from damage.

Material and process: This kind of pipe is scientifically compounded using high-performance modified epoxy resin and special formula, combining the excellent properties of steel wire and polyethylene.

Excellent rigidity and flexibility of wire mesh skeleton polyethylene pipe for underground coal mines: Since the high-strength steel wire reinforcement is coated in continuous thermoplastic plastic, this composite pipe overcomes the shortcomings of steel pipes and plastic pipes, while maintaining their respective advantages. It has the characteristics of strength, rigidity, and impact resistance that exceed ordinary pure plastic pipes, and is similar to the low linear expansion coefficient and creep resistance of steel pipes. At the same time, it has the excellent toughness and flexibility of PE pipes .

Steel mesh skeleton polyethylene composite pipes used in coal mines can be connected in different ways according to the usage requirements.

Purpose: Steel mesh skeleton polyethylene liquid pipes for underground coal mines are mainly used for pipe networks such as water supply, drainage, ventilation and gas drainage in underground mines. In addition, it can also be used to transport liquids, oils and gases, has good corrosion resistance and wear resistance, and can withstand high temperature and high pressure water erosion.

The wear resistance of steel mesh skeleton polyethylene pipes used in coal mines: A comparative test of the wear resistance of PE pipes and steel pipes shows that the wear resistance of HDPE pipes is 4 times that of steel pipes . In the field of slurry transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means HDPE pipes have better service life and better economy.

Steel mesh skeleton polyethylene liquid pipe has the characteristics of high strength, good flexibility, high temperature resistance and wear resistance. Due to the high-strength connection between the steel wire and the polyethylene, it is more impact-resistant and tensile-resistant than ordinary plastic pipes. At the same time , both steel wire and polyethylene have excellent wear resistance, making the pipe perform well in the underground coal mine environment.

Corrosion resistance: The underground environment of coal mines usually contains various corrosive substances, such as hydrogen sulfide, sulfur dioxide, etc. The steel mesh skeleton polyethylene gas pipe uses high-quality polyethylene material as the matrix, which has good corrosion resistance and can effectively resist the erosion of these corrosive substances and extend the service life of the pipeline.

Good flexibility: The wire mesh skeleton polyethylene gas pipe has good flexibility and can adapt to the complex terrain and installation methods of coal mines. This makes the pipeline more flexible and convenient during installation, while also being able to resist a certain degree of vibration and impact.

The largest flow capacity of wire mesh skeleton polyethylene pipe used in coal mines: PE pipe has a smooth inner surface, and its Manning coefficient is 0.009 . The smooth performance and non-adhesive characteristics make PE pipe have a higher transmission capacity than traditional pipes, and also reduce the pressure loss and water transmission energy consumption of the pipeline. The flow capacity of PE pipe is more than 30% higher than other general pipes .

Good construction performance of steel mesh skeleton polyethylene pipes for underground coal mines: PE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to transport and install, convenient, fast, stable, and easy to construct, reducing manpower and equipment requirements. This means that the installation cost of the project is greatly reduced. Complete specifications and models, better quality assurance.
