1.Properties:
HDPE corrugated drainage pipes made by HDPE additives to form the
corrugated shape pipe for seep and drain water. Light weight,
strong pressure, bending performance, unique structure, high
strength, impact resistance; smooth wall, a small frictional
resistance, the largest circulation; corrosion-resistant, non-toxic
pollution, environmental protection and outstanding performance;
convenient connections,excellent joint sealing, and no leakage;
light weight , construction speed, low-cost, short construction
period; buried life more than 50 years.
2.Usage:
Widely used in highway,railway roadbed,the subway project,waste
landfill,tunnels,and green belts,sports grounds and high moisture
content slope protection,for drainage.

Specification requirement KN/m2 | ≥4 | ≥6.3 | ≥8 |
Note: We can produce pipes with different ring stiffness according
to customers requirement. |
5.Connect Method ：
Faucet in the same direction with stream, use two of "O" rubber
ring were installed in the first and second sealed socket.If choose
one ring only, must be installed on the second sealed socket.
Finally, in the mouth for sealing wall and smearing grease on the
apron,
insert tightening apparatus in the mouth, straight to bottom line,
complete the Socket-drainage link.
