Spiral Grooved

Internal spiral-grooved straights and pipe and tube bends increase turblence of materials passing through the system to reduce clogging due to angel hair or stringers. Available in:

  • Bends and straights
  • Aluminum and stainless steel
  • Sizes range from 2” O.D. through 8” IPS


Some plastic pellets cannot be conveyed by conventional smooth tubing due to stringers and angel hair. The angel-hair problem requires special treatment. Heli-Groove is specifically designed as a highly effective solution. Very simply, Heli-Groove prevents angel-hair residue from collecting. Grooved Elbows are also available.
