I. Product Introduction

DN225 large-diameter PE water supply pipes and fittings are produced using imported PE100 or PE80 as raw materials. Their specifications, dimensions, and performance comply with standard requirements, and their hygienic performance meets standards as well as the relevant national health department's safety evaluation regulations. PE environmentally friendly and healthy water supply pipes offer advantages such as excellent flexibility, strong corrosion resistance, lightweight, and superior impact resistance. Pipes and fittings can be connected using methods like heat fusion socket, heat fusion butt, and electrofusion, integrating pipes and fittings into one system, ensuring safety and reliability with low construction costs. The rapid development in engineering applications promotes the widespread use of PE pipes, aligning with the guidelines of the National Ministry of Construction and the State Economic and Trade Commission for developing chemical building materials and meeting the growing needs of improving living standards.

II. Pipeline Connection:

Electrofusion Connection: Special electrofusion welding machines are used to connect straight pipes to straight pipes or straight pipes to fittings. Generally used for pipes below 160mm.

Heat Fusion Butt Connection: Special butt welding machines are used to connect pipelines, generally used for pipes above 160mm.

Steel-Plastic Connection: Methods such as flanges or threaded connections can be used.

To facilitate construction and ensure quality, corresponding tools should be prepared.

For example: rotary cutters—for cutting pipes; rotary scrapers—for removing oxide scale from pipe surfaces; wall-climbing scrapers—for removing scale from large-diameter pipe surfaces; gas shut-off tools—for on-site gas shut-off operations.

Characteristics of Large Diameter PE Water Supply Pipes

1. Long Service Life: Under normal conditions, the lifespan reaches 50 years.

2. Excellent Hygiene: PE pipes are non-toxic, contain no heavy metal additives, do not scale, and do not breed bacteria, effectively solving the problem of secondary pollution in drinking water. They comply with safety evaluation standards and relevant national health department hygiene and safety evaluation regulations.

3. Resistance to Various Chemical Media Corrosion: No electrochemical corrosion.

4. Smooth Inner Wall, Extremely Low Friction Coefficient: Improves medium flow capacity and offers excellent wear resistance.

5. Good Flexibility, High Impact Strength, Resistant to Strong Vibrations and Twisting.

6. Lightweight, Easy to Transport and Install.

7. Unique Electrofusion and Heat Fusion Butt/Socket Connection Techniques: Ensure joint strength matches the pipe body, providing safe and reliable connections.

8. Simple Welding Process, Convenient Construction, Low Overall Project Cost.

9. PE environmentally friendly and healthy water supply pipes are blue. Pipes above DN110 are blue or black with blue lines. Other colors require customization. Fittings correspond to the pipe color.
