※ Product Introduction
Plastic pipes used in coal mines are high-performance engineering plastic piping systems designed specifically for harsh environments underground. It gradually replaces traditional metal pipes such as steel pipes and cast iron pipes, and has become a key material for modern coal mine safety production, efficient transportation, and environmental protection due to its excellent corrosion resistance, light weight, easy installation, and low fluid resistance. These pipes must comply with strict national safety standards and possess safety properties such as flame retardancy and anti-static.
Plastic pipes used underground in coal mines are indispensable "blood vessels" and "nerves" in modern coal mine construction. With their comprehensive advantages of safety, durability, economy, and efficiency, they provide a solid material foundation for the safe production, energy conservation, emission reduction, and efficient operation of coal mines. Choosing suitable plastic pipes for mining is an important part of building modern and intelligent mines.
※ Product Features
1. Intrinsically safe flame retardancyAfter the evacuation of the open flame, it can extinguish on its own and will not continue to burn, preventing the fire from spreading along the pipeline.
2. Anti staticThe surface resistance value is controlled within a safe range, effectively preventing the accumulation of static electricity and the generation of electric sparks, and avoiding the ignition of flammable and explosive gases (such as gas) underground.
3. Excellent corrosion resistance performanceCan resist the erosion of chemical substances such as acid, alkali, salt, etc. in mine water, will not rust or scale like metal pipes, has a long service life, and can reach50Years or more.
3. Lightweight and easy to installThe density is only about 1/8 of steel pipes, greatly reducing the handling and construction intensity. Usually using socket connections, flange connections, etc., the installation speed is fast, the efficiency is high, and it can significantly shorten the construction period and reduce labor costs.
4. Excellent hydraulic performanceSmooth inner wall, low friction coefficient, and low conveying resistance. Under the same pipe diameter, it can increase the conveying capacity by about 30% compared to metal pipes, and the energy-saving effect is significant.
5High mechanical strength and toughnessHas good impact resistance, compression resistance, and wear resistance, can withstand certain formation pressure and external impact, and is not easily deformed or broken. Sanitary and environmentally friendly materials are non-toxic and odorless, and will not cause secondary pollution to the water supply and quality in mines.
