TufSeam Coke Drum Insulation Panel

TufSeam is the most advanced coke drum insulation panel system available today. Our system provides long-term maintenance-free thermal control. Saving hundreds of thousands of dollars by not having to replace the system due to fastener failure, water intrusion and drum damage from expansion restriction or cold spots.

Each system is pre-fabricated in our factory to meet the highest quality control standards. TufSeam is custom engineered for your specific drum size and structure restrictions.

Benefits and Features

The stainless outer shell combined with a standing seam provides a weather proof, durable, maintenance -free coke drum insulation which allows thermal movement. The internal floating ring or support cage holds the system off the drum allowing drum movement without damaging the insulation. The screw attachment to the floating ring or support cage and the single folded standing seam allows the panel removal / replacement during weld seam inspection. The panels are designed and manufactured to allow ease of handling and thermal movement.

Application Considerations: TufSeam Coke Drum Insulation Panel System

Insulation system specifically engineered for long term coke drum insulation. The system is designed to take in consideration the constant thermal expansion and contraction a drum goes through in its cycle. The system can be installed on existing drums on a turn-around basis, or on a totally new drum. The floating rings can be designed to be installed on welded clips or non-welded "Bird-Cage" straps. Either system will insure a long term efficient insulation system which will allow inspection of at risk weld seams on the vessel.

Coke Drum Insulation Body

The sidewall panel length is engineered to allow for vertical drum expansion, ease of handling in installation, and ease of inspection of weld seams. The floating support ring or support cage allows the drum to expand horizontally and not affect insulation system. The sidewalls have a single folded seam which ensures a dry system during driving rain.

Coke Drum Insulation Head

The head is installed with a prefabricated multiple layered insulation modules encased in stainless steel foil and hex mesh, and covered with a stainless steel standing seam jacket. This prevents water intrusion into the system causing cold spots and warping.

Coke Drum Insulation Cone and Hot Box

To prevent steam intrusion, the system is jacketed in .020 inch thick stainless steel with double folded standing seams. The head and cone have double folded standing seams which keeps the high pressure water on the head and steam cloud on the cone from entering the system and corroding the drum.

Turn-Around Installation

Because the system is pre-designed and fabricated, it allows easy and rapid installation of panel modules. With each panel individually attached to the floating ring, a single panel or complete row can be removed and replaced without involving the rest of the drum's panels after an In-service Weld Inspection.


Stainless steel jacketing with standing seams allows coke dust to be washed off of drums without compromising the efficiency of the insulation system.
