PIPE-LINE SYSTEMS; PIPE-LINES (pumps or compressors F04; fluid dynamics F15D; valves or the like F16K; pipes, laying pipes, supports, joints, branches, repairing, work on the entire line, accessories F16L; steam traps or the like F16T; fluid-pressure electric cables H01B 9/06)
Definition statement
This subclass/group covers:

The way of operating pipelines for transporting gas or liquids like crude oil. The main subject-matter of this subclass is dealing with preventing of fluid leaks, e.g. gas leaks, monitoring losses of fluids or locating losses of fluid.

Relationship between large subject matter areas

This group deals with the operating of pipelines and does not deal with the construction of pipelines, which is relevant for subclass F16L.

Definition statement
This subclass/group covers:

The way of conveying fluids, like two phase gas liquid mixtures, gas, liquids or viscous products, slurries comprising solid particles within a fluid. This group also includes systems to reduce friction and improve flow in pipe lines.

Arrangements for supervising or controlling working operations
Definition statement
This subclass/group covers:
  • Supervision and control of the conveyance of one or several products.
  • Arrangements for sampling fluid from the pipe-line or for injecting a composition into the pipe-line.

Definition statement
This subclass/group covers:

The prevention of gas leaks, or the monitoring of losses of fluids or the locating of losses of fluid.

Protection or monitoring of installation or pipelines

Protection of installations or persons from the effects of high voltage induced in the pipe-line
