U.S. Bellows custom designed and fabricated this 90″ diameter radius long elbow duct assembly for an ammonia plant in Louisiana. The duct assembly shown here is being sent for painting before it is shipped. The assembly was fabricated from A-516 Gr. 70 carbon steel material and designed for 16 psig and full vacuum at 302°F. A 100% dye penetrant test, and spot x-ray test of all pipe circumferential and long seam welds was performed prior to shipment.
