Full title and description

NACE SP0106-2018 — Control of Internal Corrosion in Steel Pipelines and Piping Systems. This NACE (now AMPP) recommended practice provides guidance and minimum requirements for establishing and managing programs to control internal corrosion in steel pipelines and piping used to gather, transport, store or distribute crude oil, petroleum products and gas.

Abstract

NACE SP0106-2018 summarizes best practices for identification, assessment, mitigation and monitoring of internal corrosion threats in carbon-steel pipeline and piping systems. Topics include system characterization, corrosion mechanisms (including CO2, H2S, water- and solids-related corrosion and MIC), selection and qualification of mitigation measures (chemical inhibitors, pigging/cleaning, dehydration, internal coatings, materials selection), and recommended inspection/monitoring and recordkeeping practices. The document is intended as a practical reference for operators and corrosion specialists responsible for pipeline integrity.

Scope

NACE SP0106-2018 applies to internal corrosion control for steel pipelines and piping systems used for crude oil gathering and flow lines, crude oil transmission, hydrocarbon products, gas gathering and flow lines, gas transmission and distribution, storage systems, produced water lines and injection water lines. It is presented as guidance to establish minimum requirements for program elements rather than prescriptive instructions for every possible operational condition.

Key topics and requirements

• System characterization: identifying fluids, phases, water and solids content, flow regimes and operating conditions that influence internal corrosion risk.
• Corrosion mechanisms: CO2 and H2S corrosion, oxygen, water/solids accumulation, microbiologically influenced corrosion (MIC) and localized attack.
• Mitigation methods: chemical corrosion inhibitors, pigging/mechanical cleaning, dehydration/drying, biocide and oxygen scavengers, internal coatings and corrosion-resistant materials.
• Monitoring and inspection: corrosion-rate measurement, coupon/ER probes, inline inspection (where applicable), pigging records, laboratory qualification of inhibitors and operational data collection.
• Program management: qualification of personnel, documented procedures, effectiveness criteria, recordkeeping and periodic review of mitigation performance.
• Limitations: the standard does not attempt to prescribe a single remedy for all circumstances and excludes steam lines and some internal cracking failure mechanisms; application requires competent technical judgement.

Typical use and users

Primary users are pipeline and utility operators, pipeline engineering and integrity teams, corrosion control specialists, inspection and maintenance contractors, consultants, and relevant regulatory or government agencies. The standard is used to develop or update internal corrosion control programs, to qualify chemical treatments and pigging strategies, and as a reference within pipeline integrity management and design practices.

Related standards

Commonly referenced companion NACE/AMPP documents include the prior edition NACE SP0106-2006, NACE SP0169 (control of external corrosion on buried/submerged metallic piping systems), NACE SP0206/SP0208 (internal corrosion direct assessment methodologies), NACE SP0110 (wet gas ICDA) and various NACE technical methods (TM series) for measurement and testing. Industry guidance such as API recommended practices also reference NACE SP0106 for internal corrosion mitigation.

FAQ

Q: What is this standard?

A: NACE SP0106-2018 is a recommended practice titled "Control of Internal Corrosion in Steel Pipelines and Piping Systems" that provides guidance to manage and mitigate internal corrosion risks in carbon-steel pipeline and piping systems used for oil, gas and hydrocarbon products.

Q: What does it cover?

A: It covers system characterization, corrosion mechanisms (including CO2, H2S, water/solids and MIC), selection and qualification of mitigation techniques (chemical inhibitors, pigging, dehydration, coatings, materials), monitoring and inspection methods, and program documentation and review. It is intended as practical guidance rather than a prescriptive code for every case.

Q: Who typically uses it?

A: Pipeline operators, integrity and maintenance engineers, corrosion specialists, third‑party inspection and pigging contractors, consultants and regulators responsible for safe, reliable operation of hydrocarbon pipeline systems.

Q: Is it current or superseded?

A: The 2018 edition (SP0106-2018) is the revised edition that supersedes NACE SP0106-2006. As published on November 28, 2018, it is the active/revised edition; users should verify whether a newer revision has been issued after March 2, 2026 before relying on it for the most current regulatory or contractual requirements.

Q: Is it part of a series?

A: Yes — SP0106 is part of the broader suite of NACE/AMPP pipeline and corrosion standards and technical methods (SP and TM series) that address internal and external corrosion, direct assessment techniques, measurement methods and related practices; many documents are cross-referenced for integrity programs.

Q: What are the key keywords?

A: Internal corrosion, pipelines, corrosion control, inhibitors, pigging, produced water, MIC, CO2, H2S, pipeline integrity.
