Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
The flange design, inner and outer conductor dimensions are standardized, by EIA, in the RS-225, 50 Ω (ohm), and RS-259, 75 Ω, standards.They are commonly referred to by the inner diameter of the outer conductor in fractional inches.
Plumbing or piping. A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange ). A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.

It is a rectangular bicolour with a field divided into green on the hoist, and red on the fly. The lesser version of the national coat of arms of Portugal ( armillary sphere and Portuguese shield) is centered over the colour boundary at ...
Standard sizes are indicated by the nominal inner diameter in millimeters for flanges 10 through 50 mm in diameter. [2] Sizes 10, 20 and 32 are less common sizes (see Renard numbers). Some sizes share their flange dimensions with their respective larger neighbor and use the same clamp size.
The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...
The 6-sphere, or hypersphere in seven dimensions, is the six-dimensional surface equidistant from a point. It has symbol S6, and the equation for the 6-sphere, radius r, centre the origin is. The volume of the space bounded by this 6-sphere is. which is 4.72477 × r7, or 0.0369 of the smallest 7-cube that contains the 6-sphere.
