1. What are the outdoor drainage pipes?
1, pvc-u water pipe
Pvc-u water pipe has smooth inner wall, low fluid resistance, excellent acid resistance, alkali resistance and corrosion resistance, and will not affect its water quality. Pvc-u water pipe has low density, long service life and convenient construction, and is widely used in water supply and drainage engineering, but its push-pull performance is relatively poor.
2. Polyethylene sewage pipe
The pe sewage pipe can be used at the temperature of -60-60 degrees. Even if it is constructed in winter, it will not be brittle, and its internal light and water flow resistance are small. Moreover, it also has good pit scraping resistance, corrosion resistance, sealing performance, wear resistance and long service life.
3.pvc-u double-walled corrugated pipe
Pvc-u double-walled corrugated pipe has a double-layer structure with smooth inner wall, small water flow resistance, good corrosion resistance and sealing performance, light weight, convenient construction and strong resistance to uneven settlement. However, its compression resistance is insufficient.
Second, what brand of water pipe is better?
