1.Electrofusion Welding: This method involves using specialized equipment to heat the pipe ends and fittings, melting the material and allowing them to fuse together.
2.Butt Fusion Welding: Similar to electrofusion welding, butt fusion welding involves heating the pipe ends and then pressing them together to create a seamless joint.
3.Flange Connections: Flange connections utilize flanges attached to the pipe ends, which are then bolted together with gaskets to create a secure seal.
4.Mechanical Couplings: Mechanical couplings are used to join pipe sections together using compression fittings or clamps, providing a quick and easy connection method.
5.Threaded Connections: Some steel wire reinforced PE composite pipes feature threaded ends, allowing them to be screwed together with compatible fittings or adapters.

Our Advantages

1. Anti-Static Properties: The pipe's anti-static properties effectively dissipate static electricity, reducing the risk of sparks or ignition in underground settings where flammable gases or dust may be present.
2. Steel Wire Reinforcement: The inclusion of steel wire reinforcement enhances the pipe's structural integrity, providing excellent resistance to external pressures, impacts, and mechanical stress commonly encountered in underground installations.
3. Corrosion Resistance: The pipe's corrosion-resistant properties ensure long-term durability and reliability in harsh underground conditions, including exposure to moisture, chemicals, and abrasive materials.
4. Flexibility: Despite its robust construction, the pipe remains flexible and easy to handle, allowing for straightforward installation and accommodating changes in terrain or layout without compromising performance.
5.Lightweight Design: The lightweight nature of the pipe simplifies transportation, handling, and installation, reducing labor costs and improving overall project efficiency.
6. Versatile Applications: Suitable for a wide range of underground applications, including mining, tunneling, construction, and infrastructure projects, the anti-static steel wire reinforced pipe offers versatile solutions for various piping needs.
