Omfang

This SAE Aerospace Standard (AS) provides required contours and limits of size of the surfaces of the internal fluid passages of tube fittings for the portions that are not already defined by the fitting end design standard drawings. Purpose The internal passages of fittings are defined by: (1) the dimensions of the fitting end design standards, (2) a through hole diameter that may be smaller than that on the fitting ends, (3) an allowable offset of holes on the same axis, (4) a minimum wall thickness of the center body section of shape fittings, and (5) a requirement for a minimum ball to pass through shape fittings. This standard provides manufacturing requirements to reduce abrupt changes in contours and thus minimize pressure drop, reduce the number of edges produced to minimize burrs and provide sufficient minimum size of fluid passages while maintaining a minimum wall thickness of the center body section, which is defined herein. The historical background of the need for this document is given in 4.1.
