Requires any exposed portion of pipeline to be 192.459: External Corrosion Control: Examination of Buried Pipeline when
examined for evidence of corrosion if the pipe is bare or Exposed
the coating is deteriorated.
If remedial action is needed, the pipe must be inspected beyond the the exposed area to determine whether additional corrosion exists
Requires external protective coatings to be applied on a 192.461: External Corrosion Control: Protective Coating
properly prepared surface, be sufficiently adhesive,
ductile, and strong, and have properties compatible with
any supplemental cathodic protection
Exposed plastic joints must be visually inspected and, if the condition must be immediately reported to appropriate company personnel
an abnormal operating condition such as an improper in accordance with company operating procedures
fusion joint or mechanical joint is noted,
Look for evidence of external corrosion on any bare pipe and evidence of deterioration of the protective coating on a coated
pipe
Check for print line date or manufacturer information and for example: leaks, gouges, or any deformation on all exposed pipe, and inspect
potential damage any exposed joints
If the exposed pipe has a protective coating, the coating evidence of deterioration, such as nicks, scratches, tears, or cuts
is examined for
If corrosion is found requiring remedial action, inspect exposed area for additional corrosion
the pipe beyond the
When inspecting the exposed pipeline, be aware of other utilities encroaching on the gas facility
Note the environment in which the pipe and pipe coating exposed
system is
The environment where pipe coating and pipe are in is moisture, bacteria, or other contaminants, such as solvent or gasoline, that could
critical because damaged coating could house cause significant "under side" or under coating corrosion, ultimately leading to
pipe failure.
While impacts of damaged coating may not be long term implications could be catastrophic

It is important to be able to recognize the different types of pipe material
