This project consisted of (4) 22,500 carbon steel pressure vessels which act as a buffer mechanism between the compressor and the fluctuating pressure caused by the changing demand for the Sphere in Las Vegas.

These vessels were 10′ ID X 35′ tangent length on a support skirt and each weighed 48,000 pounds. The shell was 3/4″ thick and the dished heads were 7/8″ nominal thickness with full x-ray on all straight seams. These vessels were designed and stamped per ASME Section VIII for 225 PSIG at 200° F.

The interior surfaces were blasted and lined with (1) coat of Rust-Oleum 9100 epoxy mastic at 5-8 mils DFT and the exterior surfaces were blasted and painted with (1) primer coat of Rust-Oleum 9100 epoxy mastic at 5-8 mils DFT & (1) finish coat of Rust-Oleum 9800 polyurethane at 1.5-3 mils DFT.

The sphere can seat 17,600 people with a standing room for 20,000 people and is the world’s largest spherical structure.
