Apex Engineered Products, a North American fabricator of heat exchangers for chemical processing plants worldwide, has completed fabrication and delivery of a 1,800-tube heat exchanger reboiler for a North American nitrogen-based fertilizer producer. The 44,000-pound unit was fabricated entirely from SA- 240-304 / 304L stainless steel and manufactured, tested, and documented in accordance with ASME Section VIII, Division 1 requirements. The construction was designed for demanding fertilizer and nitrogen-based chemical processing applications, where high temperatures, corrosive process streams, and continuous operation make equipment reliability critical. All pressure-boundary and wetted components, including the channel cover, shell, flanges, tubesheet, tubes, nozzles, baffles and tie rods, were fabricated from 304 / 304L |
stainless steel. The tubesheet features an NEN design and is welded directly to the shell on both sides, creating a fully welded shellto-tubesheet connection. Quality assurance included pressure testing before shipment, spot radiography on both shell and tube sides, Joint Efficiency verification, liquid penetrant testing, and positive material identification. The testing and documentation provide weld and material traceability across the unit’ s wetted components. The project demonstrates Apex’ s fabrication capabilities for specialized heat-transfer equipment serving fertilizer and chemical processing facilities. The company’ s work includes shelland-tube heat exchangers and equipment supporting fertilizer and ammonium nitrate production, where dependable performance and minimized unplanned downtime are essential. |
