CB&I builds stacks and chimney liners for discharging flue gases from power generation plants and other industrial applications. Our unmatched expertise in welding and metallurgy and our proven safety record translate into high-quality results and lower risk for our customers—all at a competitive price.

Quality in construction. We construct single- and double-wall stacks that may be freestanding, top-hung or guy-supported. Over the past several decades, we've built stacks as tall as 1,000 feet using a variety of materials, including high-end stainless steel, carbon steel and corrosion-resistant alloys such as Hastelloy^® and Inconel^®.

Our projects are backed by the knowledge and experience of our specialized, in-house technical groups. We maintain a sophisticated laboratory that performs metallurgical evaluations, corrosion studies and other research to help identify the most appropriate materials for the job. Our Welding and QA Technology group develops standardized policies and processes to ensure consistency of welding and quality assurance activities for all our projects.

Experienced planners in our Construction Technology group provide expertise on rigging, heavy lifting and other construction disciplines. They develop site-specific plans and procedures and select the appropriate heavy-lift cranes, temporary supports and other equipment needed to erect large components.

Safety is our top priority. When executing stack and liner projects, safety is our top priority. Over the years, we've developed construction and rigging methods that make elevated work safer and more efficient. We've implemented a comprehensive company-wide safety program and executed thousands of projects without a single lost workday or recordable incident. These accomplishments have earned us one of the best safety records in the industry and recognition from customers, industry associations and safety organizations.
