2010 Steel Pipeline and Pipe Fabrication Project of the Year Award Winners

2010 Pipe Fabrication Project of the Year

Combination Steel Fittings 
Combination steel fittings included a 102-inch x 102-inch diameter tee with three piece crotch plate reinforcement and riser pipe section fitting complete with one dished head end and two 30-inch diameter outlets.  The cylinder thickness is 3/4 inch and the crotch plate thickness is 4 inches.  The combination fitting weighed 35 tons in one piece.  An additional 102-inch diameter steel pipe was also installed to extend the riser pipe to the ground surface.

ASTM A570 grade 70 steel plates were used to fabricate the fitting and crotch plate reinforcement.  The weld seams of the fitting were stress-relieved and the whole fitting was hydrostatically tested.
