Full titles differ between systems:

IPC:

Flanged joints > the flanges being connected by members tensioned axially

CPC:

Flanged joints (F16L13/00, F16L17/00, F16L19/00 take precedence; adjustable joints F16L27/00; for hoses F16L33/00; couplings of the quick-acting type F16L37/00; for double-walled or multi-channel pipes, or pipe assemblies F16L39/00; connecting arrangements or other fittings specially adapted to be made of plastics or to be used with pipes made of plastics F16L47/00; specially adapted for pipes of brittle material F16L49/00) > the flanges being connected by members tensioned axially (F16L23/12 takes precedence)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1990.
