Characteristics:

1. Good physical property and flexibility, wearproof and shockproof quality.
2. Its installation and connection is simple and reliable, the interface strength of heat melt and electric fusion connection is higher than that of pipe itself. So no leaking, and it is called the integrated pipeline.
3. Easy construction, cost effective and long service life, light and reelable, simple welding and fast constructing, low excavation quantities; compared with metal pipe, it can save 1/3 construction cost.
4. Harmless, sanitary, is green building material; no fouling, no woolly masses, not breeding bacterium, no secondary pollution.
5. Smooth inner wall, low friction coefficient, water distribution quantity enhances above 30% under the same condition with the cast pipe.
6. 50 years service life, few or no maintenance.
