CastoTubes® are Castolin Eutectic's response to the market request for erosion-resistant pipe sections and elbows.

They consist of a mild steel tube which has been internally wearfaced with TeroMatec® 4666 alloy. This provides the exceptional wear resistance of our well-known 4666 CastoDur Diamond Plates®. Furthermore, by avoiding expensive forming operations of flat plates into tubes, seamless small diameter CastoTubes® are available.

CastoTubes® offer many advantages:

  • Exceptional wear resistance
  • Highly cost effective solutions for plant productivity
  • Lightweight
  • Easy to replace
  • Easy to join
  • Absence of harmful linear weld joints, can operate at high pressures
  • Small diameters available

Standard CastoTubes® Range
Tubes with a minimum internal diameter of 82 mm are available and a maximum length of 3 m. CastoTubes® can be installed with standard flanges so that the replacement of worn out tubes can be done quickly and easily. Virtually any inner diameter from the 82 to 282mm can be produced by applying a different wearfacing thickness inside the standard base tube. This allows a smooth joint to the existing installation so as to avoid turbulent media flow.
