UM Type expansion joints

These expansion joints can operate at high temperatures, where vibrations are present and pressure impulses occur. Expansion joints can be customized for flue gas applications and are designed for engine exhaust systems.

Product Description

Features:
  • Customized for flue gas applications, designed for engine exhaust systems.
  • Located in the engine exhaust system, in mainly two areas. The flue gas line between the engine and the turbo charger, and on the charger air lines.
  • Designed for, and operate at high temperatures, where vibrations are present and pressure impulses occur.
Benefits:
  • Highly customizable design: Bellows geometry, material options and combinations
  • Multiply bellows with low spring rate and high cycle life

With loose/ swivel flange connection:

  • Easy installation, flanges can be rotated
  • Flanges are not in contact with medium, which enables lower grade material
  • Connection with non weldable materials possible
  • Galvanic surfaces/ coatings possible
  • Gaskets can often be eliminated
