PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL

Introduced: September 1968

Description

F16L covers rigid and flexible pipes for fluid transport, encompassing design, materials, and construction methods applicable to gases, liquids, or mixed media. The class includes joints, couplings, fittings, and connectors that enable assembly and leak-free operation of piping systems, as well as mechanical supports, clamps, and fastening devices for pipes, cables, and protective tubing. Thermal insulation of pipes and general thermal insulation means for industrial applications are also included. This classification excludes specialized piping for particular industries (e.g., steam pipes in F22, automotive fuel systems in B60) and specific end-use applications covered by their respective technical fields.

Of 34 combined children, 31 exist in both systems.

2 codes are CPC-only extensions, 1 exist only in IPC.

Note: 2 CPC extensions are marked as secondary classification only.

19 shared codes have differing titles between IPC and CPC.
