HDPE

HDPE pipes are flexible hence best suited for lying in hilly and uneven terrain. Flexibility allows simple handling and installation.

METAL

Metal pipes are rigid. Any small curvature and unclear surface has to be connected with additional joints.

PVC

Very little flexibility. Normally considered rigid.

Advantages of HDPE Pipes Over Other Pipes

BACK

Inside surface is very smooth due to which pressure losses are minimal. No scale formation.

Internal surfaces are not as smooth, due to which pressure losses are possible. Chances of scale formation.

Internal surface is smooth.

HDPE pipes have excellent weldability. The butt fusion and electrofusion are very simple and most reliable welding techniques used.

Additional accessories are required for welding hence high cost association.

No weldability.

HDPE pipes are non corrosive (Metallic/Microbic). These pipes have a good resistance to acids and alkaline.

Metal pipes are corrosive in nature and require inner lining if used for transportation of corrosive media.

Chemical resistance is not as good as HDPE pipes.

Because of low density, Pipes are very light in weight. Due to light in weight, they are easy for handling, reduce transportation and installation costs.

Very heavy as compared to HDPE pipes, due to which installation and transportation is difficult.

Light in weight, but due to brittleness, handling has to be done with more care.
