Power Generation

Triad Bellows is the leading manufacturer of exhaust bellows and expansion joints for the power generation industry, delivering rugged, high-performance solutions engineered to withstand the extreme temperatures, pressures, and vibration common in both coal and natural gas facilities. With a commitment to U.S.-based manufacturing and strict adherence to ISO and industry standards, Triad ensures long-term reliability and safety across all critical plant systems.

Turbine Exhaust Systems – Absorb high-temperature thermal expansion and vibration from gas or steam turbines to protect ductwork and downstream equipment.

Boiler Piping and Ductwork (coal-fired plants) – Allow for expansion and contraction in high-pressure steam lines and flue gas ducts subjected to extreme temperature changes.

Heat Recovery Steam Generators (HRSGs) (natural gas plants) – Compensate for thermal movement in the transition ducts and steam-generating sections downstream of gas turbines.

Air Intake Systems – Handle thermal and mechanical movement in large air intake ducts, maintaining alignment and system integrity.

Flue Gas Desulfurization (FGD) and Emissions Systems – Allow movement in systems used to treat and exhaust combustion byproducts, helping to maintain proper sealing and alignment.

Pump and Fan Connections – Isolate vibration and movement at connections to large rotating equipment like boiler feed pumps, cooling water pumps, and forced draft fans.

Condensers and Cooling Systems – Manage expansion in low-pressure lines and water transfer systems in both types of plants.
