Hooper Welding has shipped its thickest pressure vessels to date. The three, 8.125” thick Steam Drums, are destined for a power plant in Saudi Arabia.

The ASME “S” Stamped steam drums weigh a combined 1,316,100 lbs and are each over 60’ in length. Each vessel is constructed of 6 shell courses of 107” x 245 5/8” (rolled to 70” ID) SA 299N plate.

The Steam Drums were completed sequentially and were shipped within a few months of each other.

Each Drum will be supported onsite by 35' long hanger rods made of 8" thick, A675-70 round bar, and 8" - 4 UNC Hex Head Nuts.
