The Anti-static Flame Retardant Colored Steel Wire Reinforced PE Composite Pipe, also known as SRTP pipe, is a revolutionary pipeline solution meticulously crafted by winding high-strength steel wires around a resilient polyethylene (PE) core. Departing from traditional carbon black conductivity methods, Shandong Donghong Pipe Industry Co., Ltd. proudly introduces our independently developed color antistatic and flame retardant technology. This innovation not only enhances safety but also offers a visually appealing bright appearance, setting a new standard in the field of standardized mine construction.
Donghong's pioneering TOP-modify material modification technology heralds a new era of safety with anti-static and flame retardant features for plastic pipes.
After five years of dedicated research and development by 12 expert researchers at Donghong, the groundbreaking TOP-modify material modification technology was successfully developed. This technology ensures that, while maintaining the exceptional tensile properties of the pipe, the surface resistance is maintained at less than105Ω. The antistatic and flame retardant performance surpasses industry standards, ensuring unparalleled safety and reliability for mining pipelines.
1. Electrofusion Welding: This advanced technique uses specialized equipment to heat the pipe ends and fittings, melting the material seamlessly to fuse them together for a robust connection.
2. Butt Fusion Welding: This method similarly entails heating the pipe ends, but then pressing them together to fabricate a seamless, enduring joint, enhancing system integrity.
3. Flange Connections: Flange connections involve attaching flanges to the pipe ends, which are subsequently bolted together with gaskets, ensuring a secure and leak-proof seal.
4. Mechanical Couplings: Mechanical couplings offer a quick and efficient way to join pipe sections, employing compression fittings or clamps for a reliable, easy-to-install connection.
5. Threaded Connections: Certain steel wire reinforced PE composite pipes feature threaded ends, enabling them to be conveniently screwed together with compatible fittings or adapters for a secure fit.
