About this file
This is an engineering drawing for a Support Cone - Air Admission component manufactured for the Hoover Dam Wide Head Turbine project. The drawing is document number 20-23-0016, associated with Contract No. R10PC30013 for the United States Bureau of Reclamation (USBR), and was prepared by Andritz Hydro Corp. The component is specified to be fabricated from ASTM A240 304L stainless steel with a combined weight of approximately 130 pounds, split into two halves of about 65 pounds each.
The drawing provides comprehensive technical specifications including detailed dimensions, tolerances, and machining requirements. Key specifications include six holes per section (12 total), reamed holes with specific tolerances of +.0015/-.0005 inches, a 250 RMS surface finish requirement, and various diameters ranging from Ø10.50 to Ø35.410. The component features 8 total gussets spaced as shown, 45-degree chamfers, and multiple reference datum points (ER 1 through ER 4). The drawing includes three views with detailed sections and is drawn to various scales (1:5 for general view, 1:3 for sections, 1:2 for details). Reference drawings for related components (Distributor Section, Upper Pipe Extension, and Lower Pipe Extension) are provided. The drawing was last revised on 2/27/2013 with geometric tolerances added for clarity.
