    Note: 1. For pressure classes ≤600, the standard flange sealing type is "RF." If using "RJ" (ring-type seal) or "LF" (large concave face), please specify accordingly.

    2. The structural length L of the ANSI ring-type seal (RJ) equals the structural length of the "RF" flange connection plus an "x" value.
