How the weight is estimated
The blind flange is modelled as a solid circular plate. Bolt-hole volumes are subtracted and the raised-face volume is added. The selected material density converts the resulting volume to a one-piece weight.
Small edge chamfers, machining allowances, tolerances, coatings and packaging are not included. Confirm actual weight against the approved drawing or measured product.
Standard and quotation check
Reference outside diameter, minimum thickness and bolt pattern follow the supplied ASME B16.5-2003 Class 150, 300 and 600 flange tables. Raised-face height changes with the selected class. Specify NPS, class, facing, material, quantity and destination in the RFQ.
