The material of PE water supply pipes is PE (polyethylene) resin, meticulously polymerized from monomer ethylene. By varying polymerization conditions such as pressure and temperature, we achieve different resin densities, resulting in high-density polyethylene, medium-density polyethylene, and low-density polyethylene. PE water supply pipes boast an impressive array of benefits including outstanding toughness, exceptional corrosion resistance, superior crack resistance, a stable interface, and a lightweight structure that ensures easy construction. These pipes are extensively used in the water supply industry. Beyond traditional excavation construction methods, advanced non-excavation techniques can also be employed. With a remarkable service life exceeding 50 years, polyethylene pipes are validated by both stringent international standards and cutting-edge foreign benchmarks, as well as through practical application.

2. Polyethylene pipes must be connected using PE pipes and fittings of the same brand, material, and SDR rating to ensure compatibility and reliability. Prior to commencing the connection, conduct a comprehensive test to confirm the quality meets the required standards, guaranteeing a secure and long-lasting pipeline.
3. When joining polyethylene water supply pipelines, maintain pristine pipe ends to ensure a seamless and efficient connection. Temporarily seal pipe openings at the end of each work session to prevent contamination. Immediately inspect the interface upon completing the connection to ensure it is secure and free of defects.
5. Follow the prescribed pressure holding and cooling durations for hot melt butt welding as stipulated by the equipment and pipe manufacturers. During these periods, it is crucial not to move or apply pressure to the connecting parts to ensure a strong and stable connection.
6. Post-connection, it is essential to conduct a water pressure test on the pipes within 1 hour after completing the hot-melt weld to ensure the integrity and reliability of the pipeline. Secure the pipeline and expose the joints prior to the hydrostatic test. Fill the pipeline with water, purge all air, and then check for water tightness to confirm a successful connection.
7. The pipeline engineering construction can only be deemed operational after successfully passing the final acceptance inspection, ensuring that all standards and specifications have been met for a safe and effective water supply system.
