How do we calculate?
According to ASME B16.36, orifice flanges are weld neck (or slip-on) and at least Class 300; because of the tap hole the flange thickness is at least 38 mm (1.5"). The pressure taps are drilled opposite each other, 1" (25.4 mm) from each face of the orifice plate. This tool prepares the correct description for ordering.
