I. Product Introduction

The 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 the standards and relevant national health department 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 such as hot melt socket fusion, hot melt butt fusion, and electrofusion, integrating pipes and fittings into a single unit. This ensures a safe and reliable system with low construction costs, leading to rapid development in engineering applications. Promoting the use of PE pipes aligns with the guidelines of the National Ministry of Construction and the National Economic and Trade Commission for developing chemical building materials and meets the growing needs of improving living standards.

II. Pipe Connection Methods:

Electrofusion Connection: Specialized electrofusion welding machines are used to connect straight pipes to straight pipes or straight pipes to fittings. This method is generally used for pipes with diameters below 160 mm.

Hot Melt Butt Fusion Connection: Specialized butt welding machines are used to connect pipes. This method is generally used for pipes with diameters above 160 mm.

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 layers on the pipe surface; wall-climbing scrapers—for removing oxide layers on large-diameter pipe surfaces; gas shut-off tools—for on-site gas shut-off operations.

Features 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 addressing the issue of secondary contamination in drinking water. They comply with safety evaluation standards and relevant national health department hygiene and safety evaluation regulations.

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

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

5. Good Flexibility and High Impact Strength: Resistant to strong vibrations and twisting.

6. Lightweight: Easy to transport and install.

7. Unique Electrofusion and Hot Melt Connection Technologies: Ensure joint strength matches that of the pipe itself, providing safe and reliable connections.

8. Simple Welding Process and Convenient Construction: Low overall project cost.

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