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 regulations for drinking water safety evaluation. PE environmentally friendly and healthy water supply pipes offer advantages such as excellent flexibility, strong corrosion resistance, lightweight, and outstanding 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, ensuring system safety and reliability with low construction costs. They have developed rapidly 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: Uses a dedicated electrofusion welding machine to connect straight pipes to straight pipes or straight pipes to fittings. Generally used for pipes below 160mm.

Heat Fusion Butt Connection: Uses a dedicated butt welding machine to connect pipelines. Generally used for pipes above 160mm.

Steel-Plastic Connection: Can be connected using methods such as flanges or threaded couplings.

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

For example: Rotary cutter—for cutting pipes; Rotary scraper—for removing oxide scale from the pipe surface; Wall-climbing scraper—for removing scale from large-diameter pipe surfaces; Gas shut-off tool—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 national health department hygiene and safety regulations.

3. Resistant to corrosion by various chemical media: No electrochemical corrosion.

4. Smooth inner wall with an extremely low friction coefficient, improving medium flow capacity and offering excellent wear resistance.

5. Good flexibility, high impact strength, and resistance 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 equal to the pipe itself, guaranteeing safe and reliable connections.

8. Simple welding process, convenient construction, and low comprehensive project cost.

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