Full titles differ between systems:

IPC:

Pipe-line systems > for gases or vapours > Arrangements for producing propulsion of gases or vapours

CPC:

Pipe-line systems (conveying articles or materials through a pipe- line by means of a fluid carrier B65G51/00, B65G53/00; liquids B67D; special devices for transferring liquids from bulk storage containers into vehicles or boats or vice versa, e.g. loading or unloading vehicles or portable containers B67D7/00; conveying material which has been excavated by a dredger or soil shifter through a pipe-line E02F7/10; sewer pipe-line systems E03F3/00; thermal insulation of pipe-lines F16L59/00; central heating systems F24D) > for gases or vapours > Arrangements for producing propulsion of gases or vapours

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
