HDPE Pipe
Piping made of polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrialmarine, mining, landfill, duct and agricultural applications. t has been tested and proven effective for above groundsurface, buried, sliplined, floating, and sub-surface marine applications.High-density polyethylene pipe (HDPE) can carry potable water, wastewater, sluries, chemicals, hazardbous wastes.and compressed gases. Polyethylene is strong, extremely tough and very durable.
- Marine, mining, landfill, duct and agricultural applications.
- Carry potable water, wastewater, slurries.
- Chemicals, hazardBous wastesand compressed gases.
HDPE Pipe Feature
High corrosion resistance, resulting into a longer life.
High impact strength.
Extremely light weight and hence easy to handle.
High flexibility.
High abrasion resistance.
Earthquake resistance.
No infiltration, helps maintaining the quality of fluids being conveyed.
No trenches needed, resulting into easy and economicalinstallation.
High UV resistance to scaling and biological build upAllows fusion to eliminate leakages.
