Erosion Resistant | CastoTube®

Supplier: SMENCO

When the world's toughest industries went searching for the best wear and erosion-resistant pipes and elbows, naturally they came to Castolin Eutectic, the world leaders in wear and fusion technologies.


The result? Castolin Eutectic developed CastoTube® and CDP® WearPlate - these tough, wear resistant composite materials consist of an easy-to-weld base steel plate or tube overlaid with abrasion and erosion resistant alloys by utilising processes such as arc welding, metal atomisation or plasma powder coating. 

The CDP® and CastoTube® production units use the latest robotised manufacturing technologies and vacuum fusion techniques to ensure the highest degree of process stability, regularity of anti-wear characteristics and surface finish
Industries and applications:
CastoTube® is installed in extremely demanding applications:
  • Cement and concrete
  • Mines and quarries
  • Sand and gravel pits
  • Shredders and recycling plants
  • Iron and steel mills
  • Cement and ready-mix concrete plants
  • Brickworks
  • Foundries and coking plants
  • Incineration plants and electric power stations
For mining CastoTube consists of a mild steel tube which has been internally wearfaced with TeroMatec® 4666 alloy. Applied internal coating thicknesses are typically 3-4.5mm. 
The TeroMatec® 4666 wearfacing alloy contains multiple hard phases throughout the coating that contain hard phases 1500-2700 HV which resist abrasion and erosion at temperatures up to 500°C.
This provides the exceptional wear resistance of the well-known 4666 CastoDur Diamond Plates®. By avoiding expensive forming operations of flat plates into tubes, seamless small diameter CastoTube® are available.
CastoTube® offers many advantages:
  • Exceptional wear resistance
  • Extremely 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 CastoTube® 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 82mm 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. CastoTube® can be fabricated into "lobster back bends" to suit your plant and machinery.
