Abrasion Resistant
PE is abrasion resistant and is well suited for the solids environment in sewer applications and butt fusion welding machine.http://www.zjbuttfusion.com

Construction Advantages (butt fusion welding machine)
The combination of flexibility and leak-free joints allow for unique and cost-effective types of installation methods that the rigid PVC and Ductile Iron pipes can’t use with bell-and-spigot connections. These alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Sliplining, Plow and Plant, Submerged or Floating Pipe, etc.) can save considerable time and money in most applications.
Polyethylene pipe is produced in straight lengths up to 50 feet long and coiled in diameters up through 6 inches. Coiled lengths over 1,000 feet are available (depending on size) providing low cost installations.
Polyethylene is about one-eighth the density of steel and does not require the use of heavy lifting equipment for installation.

Flexible and Fatigue Resistant
HDPE pipe can be bent to a radius 25 times the nominal pipe diameter (Example: 12 inches of HDPE can be cold formed in the field to a 25-foot radius). This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with alternate materials.
The flexibility of HDPE pressure pipe makes it well suited for dynamic soils including areas prone to earthquake.
HDPE pressure pipe can accept repetitive pressure surges that significantly exceed the static pressure rating of the pipe.
