Fabrication of High Pressure Carbon Steel ASME Vessels for the Military
We were recently contracted by a military customer to custom fabricate these twin carbon steel vessels. Designed for use as hydro-pneumatic vessels, they would contain hot water and require special finishes, coatings, and insulation. Composed of an A516 GR70 carbon steel, all of the vessel components were formed in-house, utilizing our advanced shearing, metal forming, and welding capabilities.
After assembly, the vessels interior surfaces received a near-white metal blast per SSPC-SP-10 standards, followed by the application of a 646 mill white Macropoxy coating. The exterior surfaces were prepared with SSPC-SP-6 commercial blasting, and finished with a Durethane Fast Clad coating, prior to insulation. The finished vessels featured dimensions of 72” in diameter and 19.5’ in height, with a capacity of 4,620 gallons each, and can accommodate water up to 120°F, at 400 psi. This vessel project met ASME Section VIII, Div. 1 standards and was completed, from fabrication to installation, in just 14 weeks.
