DURITE® is an abrasion resistant, low chromium cast iron (modified ASTM A532) with a nominal hardness of 400 BHN. DURITE fittings are the primary option used in all pneumatic and hydraulic systems conveying abrasive materials. DURITE pipe spools are used in straight piping routes for high wear locations.

  • Abrasion resistant for a variety of ash handling applications
  • DURITE C - 400 BHN standard in most applications
  • DURITE H - 600 BHN option in highly abrasive applications
  • Beveled End allows for positive clamping and assured connection

  1. Does UCC recommend to cut DURITE?[+]
    No, UCC does not recommend cutting cast components due to materials of construction and connection mechanisms.
  2. What is the maximum length of a DURITE spool piece? [+]
    The maximum length of a DURITE spool piece is 6 feet.
  3. Where is DURITE commonly used? [+]

    DURITE wear sections are used downstream of change in direction for improved abrasion resistance in highly turbulent areas.

  4. Can DURITE be welded?[+]

    No, welding will cause cracking/annealing of DURITE piece.

  5. What is the average service life for a straight run of DURITE?[+]

    250,000 tons of ash, provided the pipe is rotated twice from its original position to equalize wear(120° per rotation).

  6. Is special handling required for DURITE?[+]

    Due to the high hardness of DURITE it is a brittle material and requires special handling.

NUVA FEEDER Dilute Phase Pressure System

The NUVA FEEDER® pressure system is optimal where conveying capacity requirements exceed the limits of a vacuum system. 

MultiDAC Dense Phase Pressure System

The MultiDAC™ system is intended primarily for short conveying distances.  Learn more about our MultiDAC Pressure System.


DEPAC Dense Phase Pressure System

DEPAC® is a dense phase system for conveying large quantity of material at low velocity over very long distances. 


Vacuum Systems

The NUVEYOR® Vacuum System is an industry standard for efficient, reliable ash removal and is capable of conveying up to 80 TPH and distances of 1500 ft (450m).


Ideal for converting wet sluice systems into a “dry” ash system without change to the existing bottom ash hoppers.


Pneumatic Systems

UCC pioneered the first dry bottom ash system using pneumatic technology in 1920. The PAX Pneumatic Ash Extractor added new technology to this time-proven vacuum system design and offers many benefits over wet bottom ash systems.

Lime Handling

Lime Handling systems for wet scrubbers, dry scrubbers and fluidized bed boiler (FBB) applications.
