2017/01/18· Officials decided to install a 48-inch HDPE DR 32.5 pipe and pump the raw water the last 13,000 feet from the pump station to the plant. The old canal system would provide the path the pipe would take, requiring no digging or Puhui Pipe manufacturer in China
/06/11· HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or HDPE mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene) , its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.
MUNICIPEX is more flexible than HDPE or composite pipes and will resist kinking even at temperatures well below freezing. Kinking can be prevented by bending the pipe more slowly in cold temperatures, taking care not to bend
