Power Generation Joints

Sector: Power Generation

Background

Teconnex Bellows was commissioned to supply 358 pipe penetration seals for a large-scale power generation project in Canada. 

This project uses Heat Recovery Steam Generators (HRSGs) designed to generate steam from the flue gas of a combustion turbine. Each HSRG has three pressure levels and a reheat section, with a horizontal gas path and natural circulation system. 

Challenge

The bellows would become an integral part of the system, and needed to meet demanding criteria:

• Withstand high temperatures and pressures
• Accommodate thermal expansion and movement within the HRSG system 
• Deliver long-term durability under continuous heavy-duty operation

Solution

Teconnex Bellows provided a fully tailored solution:

• Precision-Engineered Seals: 358 custom-designed bellows built to handle continuous operation in high-stress environments.
• Seamless Integration: Designed specifically for compatibility with the HRSG’s pressure boundaries and thermal cycling.
• Built for Endurance: Manufactured using high-grade materials and strict quality controls to ensure long-lasting performance.

These pipe penetration seals enable safe and efficient movement of pipework through the HRSG casing while maintaining pressure containment.

Result

This successful delivery demonstrates our continued commitment to engineering excellence and dependable service in the global energy sector. Teconnex Bellows’ pipe penetration seals are now supporting high-efficiency, low-emission power generation at the power plant. 

We have also collaborated with this client on various projects in Taiwan, Korea, and Brazil.
