The Anti-static Flame Retardant Colored Steel Wire Reinforced PE Composite Pipe, also referred to as the SRTP Pipe, is a revolutionary pipeline innovation. Crafted by expertly winding high-strength steel wires around a robust polyethylene (PE) core, this solution transcends traditional carbon black conductivity methods. Our company's groundbreaking research has led to a vibrant, color-antistatic, and flame-retardant design that marks a significant milestone in standardized mining construction.
Introducing Donghong's TOP-modify material modification technology, setting a new standard of safety in the realm of anti-static flame-retardant plastic pipes.
After five years of dedicated research by 12 Donghong researchers, we proudly present the advanced TOP-modify material modification technology. This innovation not only maintains the tensile strength of the pipe but also ensures surface resistance <105Ω. With superior antistatic and flame retardant properties surpassing industry standards, our pipe guarantees unparalleled safety in mining pipeline applications.
1. Electrofusion Welding: This advanced technique uses specialized equipment to meticulously heat the ends of the pipe and fittings. By melting the HDPE material, it allows for a precise and robust fusion, forming a solid and seamless connection.
2. Butt Fusion Welding: In this method, the pipe ends are heated and then pressed together, creating a flawless and continuous joint. This technique ensures a strong and durable connection, ideal for high-pressure applications.
3. Flange Connections: Flange connections involve attaching flanges to the pipe ends, which are then securely bolted together with gaskets. This method ensures a tight seal and reliable joint, perfect for maintenance-friendly installations.
4. Mechanical Couplings: Utilizing compression fittings or clamps, mechanical couplings offer a swift and straightforward way to join pipe sections. This method provides a flexible and quick connection, ideal for both temporary and permanent installations.
5. Threaded Connections: Some steel mesh reinforced HDPE pipes are equipped with threaded ends, allowing them to be screwed together with compatible fittings or adapters. This method offers a reliable and adaptable connection, suitable for various configurations.
