Steel Stack Construction Techniques

Steel StackOver the years, Hamon Custodis has pioneered some of the most innovative steel stack erection techniques available including use of specialized lifting cranes, helicopters to lift preassembled sections in place on extremely tall stacks, and derrick systems for areas where site access or adjacent construction prohibits use of normal lifting equipment.

Steel Stack Complete Vibration and Corrosion Control

Petrochemical Steel StackPetrochemical Steel StackTwo of the biggest problems that can adversely affect steel stack operation are vibration and corrosion problems. Control of vibration that can lead to serious structural problems in steel stacks and tall steel structures due to their light mass and crosswind-induced conditions is a problem that has plagued both designers and owners of steel stacks alike. Hamon Custodis has the in-house capability to design, build, test, and install state-of-the-art vibration dampeners for use on any steel stack.

Through years of experience, Hamon Custodis has developed a thorough understanding of steel stack operation. This, combined with our ongoing association with qualified experts in corrosion control guides us in selection of appropriate materials and methods necessary to prevent corrosion. This experience has enabled us to develop corrosion-resistant stack designs that are reliable and proven over time. We are experts in lining stacks with gunite, brick, borosilicate glass block, stainless steel and high nickel alloy wallpaper, and are specialists in applying protective coatings to resist attack from highly corrosive flue gases.
