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 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. Pipes and fittings can be connected using methods like socket fusion, butt fusion, 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 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. Generally used for pipes below 160mm.

Butt Fusion Connection: Specialized 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 construction quality, corresponding tools should also be prepared.

For example: Rotary cutters—for cutting pipes; Rotary scrapers—for removing oxidation scale from the pipe surface; Crawling scrapers—for removing oxidation scale from 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 solving the problem 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 Corrosion by Various Chemical Media: No electrochemical corrosion.

4. Smooth Inner Wall, Extremely Low Friction Coefficient: Enhances 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 Butt Fusion/Socket Fusion Connection Techniques: Ensure joint strength matches that of the pipe itself, guaranteeing safe and reliable connections.

8. Simple Welding Process, Convenient Construction, Low Comprehensive Engineering 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 in color to the pipes.
