Polyethylene pipe for coal mines

The anti-static and flame-retardant components of polyethylene pipes used underground in coal mines are uniformly distributed throughout the pipe body, so the anti-static and flame-retardant performance indicators will not be affected by long-term use. The anti-static and flame-retardant properties meet national standards and are suitable for flammable and explosive environments underground.

  • Product Description

  • Flame Retardant/Anti-static

    The anti-static and flame-retardant components of polyethylene pipes for underground coal mines are evenly distributed throughout the pipe body, so the anti-static and flame-retardant performance indicators will not be affected by long-term use. The anti-static and flame-retardant properties meet national standards and are suitable for flammable and explosive environments underground.

    Lightweight/Easy Installation

    Polyethylene pipes for underground coal mines have a low density, weighing only 1/8 that of steel pipes and 1/3 that of fiberglass pipes. Therefore, transportation and installation are convenient, significantly reducing labor intensity and improving work efficiency underground.

    Good Anti-aging and Anti-rapid Cracking Performance

    Polyethylene pipes for underground coal mines have good anti-aging properties, are not easily brittle, and have good toughness and impact energy absorption. Their elongation at break exceeds 350%, and their resistance to rapid cracking is excellent, effectively preventing breakage accidents.

    Corrosion Resistant, Non-scaling

    Polyethylene pipes for underground coal mines are highly corrosion-resistant and non-scaling, making them especially suitable for transporting high-alkaline water and water containing calcium and magnesium ions underground. This saves on corrosion prevention and descaling costs, and the service life is far longer than that of steel pipes; the overall economic benefit is 6-8 times that of steel pipes.

    Self-lubricating

    Polyethylene pipes for underground coal mines have a smooth inner wall, with an equivalent absolute roughness of 2/5 that of steel pipes. This results in low transport resistance and a 30% increase in transport capacity under the same conditions.

PE wear-resistant pipe

PE wear-resistant pipe

PE wear-resistant pipe is a high-density polyethylene pipe made from modified ultra-high molecular weight polyethylene as raw material, with the addition of antioxidants, UV absorbers, flame retardants and other additives, through extrusion molding and injection molding processes. Its main features include excellent wear resistance, high internal pressure strength, good impact resistance, excellent low temperature performance and strong corrosion resistance.

PPH chemical pipe

PPH chemical pipe

PPH chemical pipes (Polypropylene-Homo, abbreviated as PPH) are alloy polypropylene pipes formed by β-modification of ordinary polypropylene materials, with a uniform and fine Beta crystalline structure. PPH chemical pipes are widely used in the chemical industry, mainly due to their excellent chemical corrosion resistance, high-temperature performance, and good physical properties. Characteristics Chemical Corrosion Resistance: PPH chemical pipes have the strongest chemical corrosion resistance among all polypropylene pipes and can withstand long-term corrosion by various acids, alkalis, and salts. High-Temperature Performance: The operating temperature can reach 100℃, and the applicable temperature range is -20℃ to 110℃, combining low-temperature impact resistance with high-temperature pressure resistance. Physical Properties: PPH chemical pipes have low density and light weight, making them easy to transport and install; they also have high strength and can withstand a certain amount of pressure. Insulation: They have good electrical insulation properties, are non-conductive, and are suitable for pipeline systems in the power industry. Application Areas Chemical Industry: PPH chemical pipes are often used to transport various chemical media, such as acids, alkalis, and salt water, and are widely used in the chemical industry due to their excellent corrosion resistance. Pharmaceutical Industry: Used to transport medicines and chemical reagents, ensuring that they do not react with the medicines and maintain the purity of the medicines. Food Industry: Meets food safety standards and is often used in food processing and transportation to ensure food safety and hygiene. Construction Industry: Used in the water supply and drainage systems of buildings, and due to their corrosion resistance and high-temperature resistance, they can effectively extend the service life of the pipelines. Power Industry: Due to their good insulation properties, they are often used as cable protection pipes in the power industry.

UPVC industrial pipe

UPVC industrial pipe

Corrosion Resistance: UPVC pipes are renowned for their excellent corrosion resistance, capable of withstanding the erosion of most acids, alkalis, salts, and other chemical substances. This makes them very popular in the chemical, industrial, and wastewater treatment fields. Temperature Resistance: UPVC pipes have relatively low temperature resistance and usually cannot exceed 60℃, otherwise they will deform or soften, limiting their application in high-temperature environments. Flexibility: UPVC pipes are rigid pipes that are not easy to bend. Precise measurement and cutting are required before installation, demanding high construction skills. Installation Convenience: UPVC pipes are usually connected using adhesive bonding or mechanical connections. The connections are well-sealed, but the installation process is relatively complex and requires professional skills and tools. Service Life: UPVC pipes have a long service life, typically exceeding 50 years. The actual lifespan depends on the operating environment, medium properties, and maintenance.
