(formerly RP0198) is titled “Control of Corrosion on Steel, Fixed Offshore Structures Associated with Petroleum Production.”
Standard techniques highlighted for scanning CUI without stripping insulation include:
Recognizing that even the best plan can fail with poor execution, these sections outline best practices for installation and quality control of both coatings and insulation. It provides clear guidance on inspection procedures for detecting CUI, including non-destructive evaluation (NDE) techniques to assess the condition of equipment without fully removing the insulation.
This article provides a detailed overview of the NACE SP0198 standard, its key sections, best practices, and where to locate the NACE SP0198 PDF for professional use. What is NACE SP0198? nace sp0198 pdf
If you need the , purchase it directly from AMPP (approx. $150–$250 for non-members, less for members). For occasional reference, check if your organization has a shared standards library. Never risk using a pirated copy for operational decisions—offshore corrosion failures are far more expensive than the cost of the PDF.
The objective of this report is to provide an overview of NACE SP0198 and highlight the best practices for designing, installing, and maintaining cathodic protection systems on reinforced concrete structures.
The consequences can be severe: leaks in pressurized piping, loss of wall thickness in storage tanks and vessels, and even catastrophic failures, all of which translate to significant financial losses, environmental damage, and safety risks.
Coatings applied for CUI service require stringent surface cleanliness (typically NACE No. 2/SSPC-SP 10 Near-White Metal Blast Cleaning) and specific anchor profiles to ensure adhesion. What is the (constant or cyclic)
: The standard outlines strategies for identifying CUI, which often involves non-destructive testing (NDT) or visual inspection by removing insulation in high-risk areas [1, 2]. Why It Matters
Your specific (Carbon steel, 300-series stainless, etc.) The operating temperature range of your equipment
This report provides a general overview and should be adapted based on specific project requirements and local regulations.
Asset integrity managers, corrosion engineers, and maintenance professionals frequently search for the to design, specify, and implement reliable protective coating systems. This article provides a comprehensive breakdown of the standard, its core methodologies, and how to apply it to prevent CUI. What is NACE SP0198? This article provides a detailed overview of the
The (published by the Association for Materials Protection and Performance - AMPP ) is the global benchmark for mitigating Corrosion Under Insulation (CUI) and fireproofing materials. CUI is one of the most critical, expensive, and hidden threats in the oil, gas, chemical, and power generation industries. Because water ingress under insulation is virtually inevitable, the document establishes a comprehensive, multi-disciplinary "systems approach" to prevent catastrophic equipment failures.
Before diving into the specifics of the standard, it is crucial to understand the problem it addresses: CUI. It is a form of external corrosion that occurs on carbon and low-alloy steels, as well as austenitic and duplex stainless steels, which are covered by thermal insulation or fireproofing materials.

Corrosion Under Insulation (CUI) is one of the most insidious and expensive problems facing the oil, gas, chemical, and power generation industries. Because CUI occurs hidden beneath thermal insulation, it often goes undetected until a catastrophic failure occurs, such as a process leak, pipe rupture, or fire.
