Mounting Stiffener Rings On The Discharge Pipe (Equipment for construction, transportation, and maintenance) Item Info

Specifications No. 2329. Picture Series 18532-3 through 18537-3. Morrison-Knudsen Co., Inc., and Peter Kiewit Sons' Co., subcontractor, Consolidated Western Steel Corp., Electric City Yard. A view of the process of mounting the stiffener rings on the discharge pipe with the aid of a compressed air-activated bull press. Rings are fabricated from quarter segments, with one joint being welded to the pipe as temporary lugs to keep the ring in alignment. 'The Bull' presses the ring into firm contact with the pipe and it is tack welded with a 4 inch fillet weld. The pipe is revolved approximately one foot by the positioning rollers, and the process is repeated until the ring is entirely tack welded. The pipe will then be rolled down the line to an automatic welder set-up (picture 18532-3) where a full fillet weld will be placed on both sides of the stiffener rings to complete the pipe for placing in the tunnel.
