Custom ASME pressure vessels — columns, reactors, separators, scrubbers, storage tanks, and specialized process equipment — engineered and shop-built under one accountable quality system, from concept through hydrostatic test.
Fintelius's vessel fabrication division designs, engineers, and builds the complete range of process pressure vessels a gas processing, petrochemical, or chemical facility needs — separation packages, columns and towers, reactor and jacketed vessels, storage tanks, and specialized separation and emissions-control equipment. Every vessel is engineered first around its process duty, then fabricated to code by the same shop, under the same quality system, regardless of which of our ten vessel product lines it belongs to.
Design and fabrication capability spans carbon steel through high-performance alloys — Inconel, Duplex/Super Duplex stainless, chrome-moly, Hastelloy, Alloy 20, titanium, and aluminum — so a single accountable shop can cover a project's full vessel scope, from a single replacement separator to a complete multi-vessel process package.
Every vessel — whatever its type — follows the same controlled path through the shop.
Process duty, feed composition, and operating conditions are analyzed and the vessel is sized and mechanically designed to code.
Plate is rolled and formed to the design diameter, height, and wall thickness the process design demands.
Trays, packing, weirs, agitators, jackets, or scrubber internals are fitted according to the vessel's function; nozzles and manways are installed.
Code-qualified welders complete all pressure-boundary welds; radiography, ultrasonic, and dye-penetrant testing verify every joint, with heat treatment where required.
Every vessel is hydrostatically tested, stamped, coated, and prepared for shipment or field erection.
