HDPE Dredger Pipe:
China HDPE Dredger Pipe:
HDPE pipes are high abrasion and corrosion resistant pipes and are made from advanced grades of PE. The material is UV Stabilized for usage in harsh marine environments. Pipes are duly coupled with HDG Flanges and stubends on boths ends and enable easy fitment by use of gaskets and galvanized buts and bolts.
Material: High Density Polyethylene
Grade: PE100
