STEEL PLANT
EXPANSION JOINTS

Expansion Joints are used in a wide range of applications within steel plants. Steel plants are large and complex plants with many pipelines, some of which are of large diameter. The piping is often placed high above ground level, which places high demands on the components used and installed as well as their design and functions. In these pipelines a large quantity of Expansion Joints is needed to absorb thermal movement.

Applications:

  • Exhaust gas ducts
  • Water lines/water pipelines
  • Chemical processing plants
  • Pipes around, and to and from,
    the blast furnaces
  • Pipelines for gas cleaning
  • Air pipes
  • Coke gas plants
  • and many more applications

Design expertise:

  • High temperatures
  • Large dimensions
  • Special designs
  • Special material requirements
  • Special insulation requirements
  • Refurbishment
