CNC Machining of a Ductile Iron Waste Gas Elbow Assembly for the
Steel Mill Application

Custom Steel Fabrication of a Ductile Iron Gas Elbow
Custom Steel Fabrication of a Ductile Iron Gas Elbow

A customer in the steel mill industry contracted Davis Machine & Fabricating for the precision machining of the waste gas elbow assembly highlighted here. Utilizing an advanced CNC horizontal boring machine, ductile iron was expertly manipulated to meet the customer specified profile. A tolerance of ± 0.001" was achieved throughout machining. The unit was then deburred to remove unwanted machining debris, and assembled as per the supplied 2D drawings. The outer castings were finished with a coating of super high heat paint. The elbow assembly was subjected to full dimensional and visual inspections to maintain accuracy and quality.

Overall part dimensions of the 90°elbow were 35" in length, 35" in width, 32" in height, and a weigh of 1,800 lbs. 72 units were produced with an 8 week turnaround time and shipped to the customer in the North East USA.
