Nace Sp0170 Pdf 2021 Jun 2026

The National Association of Corrosion Engineers (NACE) developed the SP0170 standard to provide a comprehensive framework for corrosion prevention in carbon steel pipelines. The standard outlines the requirements for coatings and cathodic protection (CP) systems, which are essential for mitigating corrosion and ensuring the safe and reliable operation of pipelines.

NACE SP0170, also known as "Control of Stray Current Corrosion," provides guidelines and best practices for the control of stray-current corrosion that can affect pipelines, metallic structures, and other infrastructure. Stray current corrosion is an electrochemical process that can lead to significant damage and leaks in pipelines and similar structures.

Austenitic stainless steels (like Types 304 and 316) and other austenitic alloys used in high-temperature, high-pressure refinery service are often in a condition called "sensitized." This means their grain boundaries are depleted of chromium and are therefore vulnerable to attack. When PTA attacks these sensitized grain boundaries, it can initiate .

Always ensure you are accessing the latest version (SP0170-2021 or the most current reaffirmation) to maintain compliance with safety regulations. Conclusion Alkaline Washing NACE SP0170, also known as "Control

For decades, engineers and integrity managers have relied on a single, critical standard to mitigate this risk: (formerly NACE MR0175). The 2021 revision of this standard represents the cutting edge of materials selection for sour service.

: The standard details the use of an aqueous solution containing soda ash (sodium carbonate, Na2CO3cap N a sub 2 cap C cap O sub 3 ) mixed with a corrosion inhibitor.
