14 High Temperatures High Pressure and Vibration Engineered Solutions Metal Exhaust Expansion Joints are designed for diesel and gas engines to absorb vibrations, axial, lateral and angular movements or any combination of these. Bredan ® UM-Types are installed on the engine before the turbo charger where high temperatures, vibrations and pressure impulses occur. UM-Types of metal expansion joints can be designed for service temperatures up to 1472 O F (800 O C) and/or pressure up to 174 PSIG (12 Barg). The bellows, the flexible component of the expansion joint, is a multi-layer construction with thinlayers of heat resistant stainless steel. Bellows materials include: • Austenitic steel • Incoloys • Inconels • Hastelloys • Titanium • Other formable materials Engine exhaust joints absorb all types of movement and vibration Exhaust Joints for Engines and Gas Turbine Systems The expansion joint provides superior flexibility and is corrosion resistant in the aggressive exhaust gas application. Bredan Metal Expansion Joints for engines are installed in: • Turbocharger Exhaust Inlet • Turbo Charger Air Outlet • Exhaust Receiver • Turbocharger Bypass • Single Pipe or Pulse • Exhaust Manifold • Engine Exhaust Line • Vehicles Exhaust Line • Generator Sets Exhaust Line Metal expansion joint for gas turbine exhaust systems are predominantly used as a pressure vessel. The expansion joint can withstand very high pressures while still absorbing thermal growth. These joints typically see a similar temperature to the internal duct temperature; this reduces or eliminates the thermal stress. Metal expansion joints are able to withstand extremely high temperatures and fast ramp rates without the thermal stress that causes yielding. When specifying expansion joints for gas turbines, stainless steel 321 is recommended for the bellows and stainless steel 321 or 347 for the connecting hardware. 321 and 347 are stabilized with titanium and columbium respectively. Liner thickness and design should be determined based on flow conditions and turbulence correction factors. EagleBurgmann EJS uses liner stiffeners welded to the liner and internal ducting.

Rectangular metal expansion joints are designed to compensate for axial, lateral and angular movements over a diverse cross section of operating conditions found in power generation, steel, petrochemical, refining, chemical, and other industries. Commonly installed in: • Gas turbine exhaust systems • Steam turbine/condenser connections • Boiler breaching • Forced draft fans • Flue gas ducts • Regenerators • Precipitators • Other hot gas, large volume ducting systems Rectangular design considerations include: • Pressure capability • Instability • Stresses due to pressure • Stresses due to deflection • Fatigue life • Spring rate and forces • Materials Rectangular expansion joint with camera corners Single miter corners Rectangular Expansion Joints for Ducting Absorbs Movements in Rectangular Ducting Rectangular product range includes two standard types of rectangular expansion joints: • A single-ply type with mitered or rounded corner configurations • A multi-ply type with radius corners Round corner Camera corner EagleBurgmann Expansion Joint Solutions calculates expansion joints according to the latest edition of EJMA Standards.
