I. Product Introduction

The DN225 large-diameter PE water supply pipes and fittings are manufactured using imported PE100 or PE80 as raw materials. Their specifications, dimensions, and performance comply with standard requirements, and their hygienic properties meet the standards as well as the relevant safety evaluation regulations of the National Health Commission. PE environmentally friendly and healthy water supply pipes offer advantages such as excellent flexibility, strong corrosion resistance, lightweight, and superior impact resistance. The pipes and fittings can be connected using methods like heat fusion socket fusion, heat fusion butt welding, and electrofusion, integrating the 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. The vigorous promotion 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. Pipeline Connection:

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 160mm.

Heat Fusion Butt Connection: Specialized butt welding machines are used to connect pipelines. This method is generally used for pipes with diameters 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 the pipe surface; wall-climbing scrapers for removing scale from large-diameter pipe surfaces; and 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 addressing the issue of secondary pollution in drinking water. They comply with safety evaluation standards and relevant health and safety evaluation regulations of the National Health Commission.

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

4. Smooth Inner Wall: Extremely low friction coefficient, correspondingly 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 that the joint strength matches that of the pipe itself, guaranteeing 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 with DN110 and above are blue or black with blue lines. Other colors require customization, and fitting colors correspond to the pipe color.
