Application for Hollow Wall Corrugated Pipe:
Hollow wall corrugated pipe has been widely used for sewerage and drainage in municipal,irrigation in agriculture, it will replace the cement pipe, cast iron pipe and other pipes. because of low cost of assembling, easy operation, easy connection and economical construction.

Features of HDPE Large Diameter Hollow Wall corrugated Pipe
1). High Ring Stiffness
2). High Brunt Intensity and low weight
3). Good creep deformation resistance.
4). Outer pressure resistance.
5). Erosion resistance ( such as acid, alkali and salt etc. )
6). Long life of approximate 50 years.
