The Fabrication of a Massive Nen Heat Exchanger

BBN Machining recently completed the fabrication of a massive NEN heat exchanger on a 19-week expedited delivery. The exchanger measured 62" OD x 54' -0" long, and weighed over 117,000 pounds. The project required the knowledge and technical expertise of many different areas of the company, including engineering, detailing, custom fabrication, CNC drilling, bundle fabrication, weld procedure development, OGTAW welding and critical QC involvement. Even our field machining team was utilized.

We have all of the tube sheet, channel, shell and cover SA 516-70N materials in inventory, which were formed and machined in-house. All of the tubes in this exchanger were orbitally strength welded, with multiple passes, to each tube sheet. After the fabrication was completed, the entire unit was PWHT in one of our furnaces.
