 POLISTAR-TUBE

POLISTAR-TUBE

POLISTAR-TUBE is made up of several layers of grinding stars riveted together. POLISTAR-TUBE grinding stars are used especially for working the inside surfaces of pipes and pipe bends. The grinding stars may be used with ¼” shank drive arbors or with PFERD’s flexible shafts.

POLISTAR-TUBE is ideal for:

  • step-by-step cleaning and finishing of inner surfaces and pipe bends
  • rounding off pipe ends and deburring bore holes
  • use in straight pipes and deep bore holes. (With this application the stars are used with drive arbors.)

Advantages

  • Extremely flexible
  • Very high-quality surface finishes up to Ra 0.2 µm can be achieved.

Recommendation for Use
The following pipe inner diameters can be worked using different diameters:

  • 2” diameter stars for inner pipe dia. 1-3/8” - 1-5/8”
  • 2-1/4” diameter stars for inner pipe dia. 1-5/8” - 1-3/4”
  • 2-3/4” diameter stars for inner pipe dia. 1-3/4” - 2”
  • 3-1/8” diameter stars for inner pipe dia. 2” - 2-1/4”
  • 3-1/2” diameter stars for inner pipe dia. 2-1/4” - 2-3/8”
  • 4” diameter stars for inner pipe dia. 2-3/8” - 2-5/8”

The different grit sizes can be used to achieve the following roughness values:

  • Grit size 60 = 1.0 - 1.3 µm Ra
  • Grit size 120 = 0.6 - 1.0 µm Ra
  • Grit size 180 = 0.4 - 0.6 µm Ra
  • Grit size 240 = 0.3 - 0.4 µm Ra
  • Grit size 320 = 0.2 - 0.3 µm Ra

To prevent corrosion forming on stainless steel (INOX) pipes, POLISTAR-TUBE is made using stainless steel rivets.
