Engineering Specification
ABC Chemical Complex
1
Corrosion Control & Monitoring
SCOPE
– This Engineering Specification includes external and internal corrosion control and monitoring for DOT regulated pipelines.
– Design, construction, construction inspection, construction acceptance, operation, and maintenance of DOT regulated pipelines are covered by this Engineering Specification.
ABC Chemical Complex
2
Corrosion Control &Monitoring
GENERAL
– All DOT regulated ABC pipelines require protection from the environment.
– Corrosive elements in the pipeline stream must be neutralized or the pipe material must be resistant to the stream.

Corrosion Control & Monitoring
Minimum requirements for corrosion control:
– External Corrosion Control
» Buried DOT regulated pipelines will be coated and cathodically protected
– Internal Corrosion Control
» Known corrosion rate based on historical data
» Corrosion rate from a national standard data base
» Data collected from laboratory prototype testing
