scope:

General

This standard presents recommended practices for the control of internal corrosion in steel pipelines and piping systems used to gather, transport, or distribute crude oil, petroleum products, or gas.

This standard serves as a guide for establishing minimum requirements for control of internal corrosion in the following systems:

(a) Crude oil gathering and flow lines

(b) Crude oil transmission

(c) Hydrocarbon products

(d) Gas gathering and flow lines

(e) Gas transmission

(f) Gas distribution

(g) Storage systems

This standard does not designate practices for every specific situation because the complexity of pipeline inputs and configurations precludes standardizing all internal corrosion control practices.

The provisions of this standard should be applied under the direction of competent persons who, by reason of knowledge of the physical sciences an the principles of engineering and mathematics acquired by education or related practical experience, are qualified to engage in the practice of corrosion control and risk assessment on carbon steel piping systems. Such persons may be registered professional engineers or persons recognized as corrosion specialists by organizations such as NACE, or engineers or technicians with suitable levels of experience, if their professional activities include internal corrosion control of buried carbon steel piping systems.
