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 properties meet national standards as well as the safety evaluation regulations of the Ministry of Health. 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 a single unit. This ensures system safety and reliability, with low construction costs, leading to rapid development in engineering applications. Promoting the use of PE pipes aligns with the guidelines of the Ministry of Construction and the State Economic and Trade Commission for developing chemical building materials and meets the growing needs of improving living standards.

II. Pipe Connection Methods:

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

Heat Fusion Butt Connection: Special butt welding machines are used to connect pipes, typically for pipes 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 pipes; and gas shut-off tools for on-site gas disconnection 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 health and safety regulations of the Ministry of Health.

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

4. Smooth Inner Wall: Extremely low friction coefficient, improving medium flow capacity and offering 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 Connection Technologies: Ensure joint strength matches the pipe body, providing safe and reliable connections.

8. Simple Welding Process: Easy construction and 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, and fittings correspond to the pipe color.
