HDPE Double-wall Corrugated Pipe for Water Drainage DWC Underground, Pipe Size 200mm to 800mm
HDPE双壁波纹管，用于排水DWC地下，管道尺寸200mm至800mm
HDPE双壁波纹管排水
优点：
1.化学稳定性：由于分子极性不足，HDPE材料在化学稳定性方面具有良好的性能;尽管几乎没有氧化剂，但大多数化学介质不能损坏;耐腐蚀和防污渍;长时间使用后内部流量不会降低; HDPE管是一种环保产品
2.可焊接强度：主要指热焊接;例如，接头少，无泄漏
3.安装方便：轻便，安装方便;可以降低安装成本，特别是在恶劣的环境下
4.较高的流量：平滑的内墙导致较低的压力损失和较高的体积
5.更好的缠绕和弯曲能力：垂直允许弯曲有利于在波动地表上的构造
6.低温保存：抗脆性温度达到-70°C，在普通低温（-30°C）下，无需采用特殊防护或保护;方便冬季安装;同时，耐压试验可通过水锤承受2.5倍额定压力
7.耐腐蚀：德国实验室证明HDPE材料的防腐蚀是铜的几倍
8.使用寿命：正确使用50年以上

HDPE double-wall corrugated pipe for drainage
Advantages:
1. Chemical stability: as lack of polarity in the molecules, the HDPE material has good performance in chemical stability; in spite of few oxidants, most of the chemical medium can not damage; corrosion resistant and anti stains; the interior flow capacity not be reduced after long time usage; HDPE pipe is a kind of environmental product
2. Formidable joint strength: mainly refer to the thermal welding; for example, few joints, no leak
3. Convenient installation: lightweight and ease of installation; can reduce installation cost, especially in bad environment
4. Higher flow capacity: smooth interior walls result in lower pressure loss and higher volume
5. Better wrap and bend ability: the vertical allowable bending benefits the construction on fluctuant earth surface
6. Low temperature preservation: anti-embrittlement temperature reaches -70°C, and under common low temperature (-30°C), no need to adopt special defending or protecting; convenient to install in winter; in the mean time, the pressure resistant test can stand 2.5 times nominal pressure by water hammer
7. Corrosion resistant: Germany lab ever proofs anti-corrosion of the HDPE material is several times than that of copper
8. Longevity: more than 50 years under proper use
