Control of Internal Corrosion in Steel

Pipelines and Piping Systems

This NACE International standard represents a consensus of those individual mem-

bers who have reviewed this document, its scope, and provisions. Its acceptance

does not in any respect preclude anyone, whether he or she has adopted the

standard or not, from manufacturing, marketing, purchasing, or using products,

processes, or procedures not in conformance with this standard. Nothing contained

in this NACE standard is to be construed as granting any right, by implication or

otherwise, to manufacture, sell, or use in connection with any method, apparatus,

or product covered by letters patent, or as indemnifying or protecting anyone

against liability for infringement of letters patent. This standard represents minimum

requirements and should in no way be interpreted as a restriction on the use of

better procedures or materials. Neither is this standard intended to apply in all

cases relating to the subject. Unpredictable circumstances may negate the

usefulness of this standard in specic instances. NACE assumes no responsibility

for the interpretation or use of this standard by other parties and accepts responsi-

bility for only those ofcial NACE interpretations issued by NACE in accordance

Users of this NACE standard are responsible for reviewing appropriate health,

safety, environmental, and regulatory documents and for determining their applica-

bility in relation to this standard prior to its use. This NACE standard may not

necessarily address all potential health and safety problems or environmental

hazards associated with the use of materials, equipment, and/or operations

detailed or referred to within this standard. Users of this NACE standard are also

responsible for establishing appropriate health, safety, and environmental protec-

tion practices, in consultation with appropriate regulatory authorities if necessary, to

achieve compliance with any existing applicable regulatory requirements prior to

the use of this standard.

CAUTIONARY NOTICE: NACE standards are subject to periodic review, and may

be revised or withdrawn at any time in accordance with NACE technical committee

procedures. NACE requires that action be taken to reafrm, revise, or withdraw this

standard no later than ve years from the date of initial publication and subsequent-

ly from the date of each reafrmation or revision. The user is cautioned to obtain

the latest edition. Purchasers of NACE standards may receive current information

ABSTRACT

This standard presents recommended

practices for the control of internal corro-

sion in steel pipelines and piping systems

used to gather, transport, or distribute

crude oil, petroleum products, or gas. It is

meant to serve as a guide for establishing

minimum requirements for control of in-

ternal corrosion in crude oil gathering and

ow lines, crude oil transmission, hydro-

carbon products, gas gathering and ow

lines, gas transmission, and gas distribu-

tion. This standard is maintained by Task

Group 038.

Foreword

The purpose of this NACE standard practice is to describe procedures and practices for achieving effective control of internal

corrosion in carbon steel pipe and piping systems used to gather, transport, or distribute crude oil, petroleum products, and

gas, including produced water and water injection pipe. Certain constituents that are found in the gas and liquid transported in

these systems (e.g., oxygen, carbon dioxide, hydrogen sulde, bacteria, etc.) can cause corrosion. Additionally, the complex

nature and interaction between constituents in the pipeline may affect whether a corrosive condition exists, or increase the

severity of a corrosive condition. These corrosive conditions can lead to localized pitting corrosion, underdeposit corrosion,

microbiologically inuenced corrosion and general corrosion. The predominant failures occur by localized pitting mechanism;

therefore controlling pitting corrosion is paramount. Identication of potentially corrosive gas and liquid in a pipeline can only

be achieved by analysis of operating conditions, uid composition, physical monitoring and/or inspection results, or other

considerations. There are many mitigation methods that can be implemented in systems where corrosive conditions exist. This

standard presents general practices in regard to control of internal corrosion in steel piping systems. This standard is intended

for use by pipeline operators, pipeline service providers, government agencies, and any other persons or companies involved

in planning, designing, or managing pipeline integrity.

This standard was prepared by Task Group (TG) 038 on Control of Internal Corrosion in Steel Pipelines and Piping Systems. It

was revised in 2018 by TG 038. TG 038 is administered by Specic Technology Group (STG) 35 on Pipeline, Tanks, and Well

Casings. This standard is issued by NACE International under the auspices of STG 35.

In NACE standards, the terms shall, must, should, and may are used in accordance with the denitions of these terms in

the NACE Publications Style Manual. The terms shall and must are used to state a requirement, and are considered

mandatory. The term should is used to state something good and is recommended, but is not considered mandatory. The

term may is used to state something considered optional.
