Pressure vessels are fabricated to ASME Section 8, Div. 1 standards and are fabricated from a variety of materials including carbon, stainless, alloy 20, monel, inconel, hastelloy & 904L. Thicknesses up to 1” and pressures up to 1000 PSIG are routinely accommodated. Radiography, liquid penetrant, magnetic particle, hydrostatic & pneumatic testing are non-destructive testing options available.
Storage tanks conforming to API 620 and API 650 standards are available in a variety of configurations, Including flat bottom, sloped bottom & elevated. These tanks are welded using semi-automatic submerged arc welding and then pickled and passivated for a smooth, clean appearance.
ASME pressurized & non-pressure columns up to approx. 100’ in height (in one piece) have been fabricated at Savannah Tank. Column internals such as demisters, support plates, distributors, & packing can be furnished upon request. The columns can be completed with all platforms and ladders supplied also.
Heating or cooling can be provided on tanks or pressure vessels by means of integrally welded dimple jackets which can be welded directly on any surface. Pressures up to 200 PSIG & temperatures up to 650 degrees F can be provided for hot water, steam or hot oil applications. Welded dimple jackets provide a means of cooling by cold water or glycol circulation, but are not recommended for rapid alternate cooling and heating cycles. Material options are carbon steel or stainless.
For improved pressure drop control, higher pressure applications & alternate heating & cooling cycles, half-pipe type jacket is recommended. Although more limited than dimple jacketing from a tank installation standpoint, half-pipe jacket is better suited for larger heat transfer areas. Material options are carbon & stainless.
