PVC mining pipes, also known as polyvinyl chloride mining pipes, are primarily used for the extraction and discharge of gas in coal mines, and are often referred to as "gas pipes." PVC mining pipes serve as an ideal replacement for traditional steel and fiberglass pipes used underground. Compared to the obsolete mining pipes, PVC mining pipes possess unique characteristics: 1. PVC mining pipes are lightweight and easy to install. The density of PVC is less than 20% of that of steel, making PVC pipes significantly lighter than steel pipes of the same diameter. In the special construction environment of coal mines, using lightweight pipes facilitates a more efficient and easier installation process, providing strong support for the normal operation of coal mines. 2. PVC mining pipes are corrosion-resistant and anti-aging. PVC materials are inert and not easily corroded; moreover, the unique environment underground, which lacks sunlight, greatly enhances their resistance to aging. 3. PVC pipes have high tensile strength and excellent crack resistance. PVC is a unique high polymer material with a dense molecular structure and strong intermolecular forces. Localized cracks are not prone to extend. Their strength ensures that they will not deform under either positive or negative pressure ventilation. 4. PVC mining pipes have self-lubricating and non-scaling properties. The inner wall of PVC pipes has minimal fluid resistance, allowing for a greater flow rate compared to other pipe materials of the same diameter, especially for liquid media. Additionally, steel pipes tend to develop a layer of dirt on the inner wall over time, which not only accelerates corrosion but also reduces the effective inner diameter of the pipes, a situation that PVC pipes do not face. 5. They are safer to use in terms of anti-static and flame-retardant properties. PVC is an inert material with inherent flame-retardant properties. Our factory produces PVC mining pipes with flame-retardant and anti-static performance that exceeds the technical standards specified in MT558.2-2005 for national coal mining PVC. Furthermore, flame-retardant and anti-static plastic pipes enhance the safety of gas transportation underground. 6. Low cost for transportation, installation, modification, and disassembly. PVC mining pipes typically use connection methods such as bell-and-spigot joints, flange connections, and threaded connections. Coupled with their lightweight nature, this makes transportation, installation, modification, and disassembly very time and labor-efficient. Applications of PVC mining pipes include: - Gas extraction (discharge) pipes in coal mines; - Protective pipes for electrical wires and cables in coal mines; - Compressed air pipelines in coal mines; - Other pressure pipelines in high gas environments underground.
