Product Description:

Large Diameter Double-wall Corrugated Pipe

Product Details

Product Introduce
HDPE double-wall corrugated pipe is a new kind of environmental protection pipe.
The outer wall of the pipe is annular corrugated structure, greatly enhance the pipe ring stiffness, thus enhances the pipeline on the soil load resistance. Compared with solid wall pipe of the same material specification, about half of the raw materials can be saved, so the cost of this kind of pipe is relatively low.
