As High Density Polyethylene (HDPE) increases its market share in targeted industries, we have also seen it grow into other markets because of its superiority to legacy materials. No other material has the flexibility, longevity, or capabilities of PE - one of those, being able to remove both the internal and external fusion bead and NOT compromise the pipe’s pressure rating.

​

For low-grade gravity lines, removing the internal fusion bead can prevent stimulated blockage and biofilm entrapment. Because of this, bead removal is increasingly included in municipality waterworks specifications across the country.

Not just for water and sewer projects either, wind and solar farm applications are requiring bead removal to lower material costs. With the internal bead removed, smaller sized conduit pipe can be used to house the cables. 

​

Mining operations utilizing large diameter pipe to transport aggregate slurries, commonly remove the bead to prevent stimulated blockage and pipe wall wear due to the turbulent flow of abrasive materials.

Removing the internal and external bead is an observed and effective practice in directional drilling, pipeline pigging operations, dual containment systems, and in conduit work.
