Introduction

Description

 

HDPE (high density polyethylene pipe) pipe is a flexible plastic pipe used to transfer fluid and gas and is often used to replace aging concrete or steel mains. Made from the thermoplastic HDPE, its high level of impermeability and strong molecular bonding makes it suitable for high-pressure pipelines.

Puhui HDPE pipe are made of superior PE100 or PE80 raw materials supplied by famous manufacturers, such as: CRP100 from Basell, HE3490-LS from Borealis and YGH041T from Sinopec, etc, which is certified as the highest quality HDPE material in the world.

Puhui HDPE pipe are used worldwide in applications such as water mains, gas mains, rural irrigation, sewer mains, slurry transfer lines, fire system supply lines, electrical and communications conduit, and stormwater and drainage pipes.
