Our Clients goal was to extend the lifespan of their aging 54” cooling tower return line, originally installed over 50 years ago, by relining it with a durable structural liner. To avoid a full system shutdown, our role was to install a 36” hot-tap and 30” bypass line, enabling our client to proceed with the relining while maintaining operations and avoiding a total outage.

Key tasks:

• Construct temporary bypass support structure.
• Install permanent steel rigging framework.
• Integrate a 54”x36” CAM flange branch tee.
