Butt Fused Joints

  • HDPE pipe can be butt fused together to form a joint that is as strong as or stronger than the pipe itself and is leak free.
  • This eliminates the potential leak points every 10-20 feet as found with PVC and Ductile Iron bell and spigot connections.
  • The Life Cycle Cost of HDPE pipe differs from other pipe materials because the “allowable water leakage” is zero rather than typical leakage rates of 10 to 20% for PVC and Ductile Iron.
  • HDPE pipe fused joints are self restraining and costly thrust re strains or thrust blocks are not required.
  • HDPE pipe’s butt fused joints simply do not leak, eliminating infiltration and ex filtration problems experienced with alternate pipe joints.

Flexible and Fatigue Resistant

  • HDPE pipe can be bent to a radius 25 times the nominal pipe diameter (Example: 315mm HDPE can be cold formed in the field to a 25 ft radius). This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with altemate 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.
