Expansion Joints

UCC offers a wide array pipe expansion joints designed to absorb thermal expansion and contraction in common piping systems due to the heat transfer from materials and airflow conveyed. They are also are designed to handle flue gas duct work and hopper movements.

Joint Types:

  • Bellows
  • NUVALOY
  • DURITE
  • Rubber

  • Absorbs movement and vibration in pipeline
  • Available in sizes 4" - 14"

  1. What is the most common expansion joint used in pneumatic applications?[+]
    Although every application has its own unique requirements, the most commonly used expansion joint in pneumatic applications is NUVALOY.
  2. What is the most common expansion joint used in sluice systems?[+]
    Although every application has its own unique requirements, the most commonly used expansion join in sluice systems is DURITE.
  3. What is the most common expansion joint used in economizer ash or a mechanical drag chain system?[+]
    The most commonly used expansion joint in an economizer ash or mechanical drag chain system is Bellows. Bellows is used in applications that transport high temperature media such as exhaust gasses or steam typically found in economizer ash systems.
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).

Vacuum-Pressure Transfer System

UCC's Vacuum/Pressure Transfer systems combine the simplicity and lower headroom requirements of a vacuum system under the hoppers with the high capacity and long distance conveying capability of a positive pressure system.

Lime Handling

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

Recirculation

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