Full title: Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments
Purpose:
Provides guidelines to prevent environmental cracking (e.g., sulfide stress cracking, hydrogen-induced cracking, stress corrosion cracking) in carbon steel weldments used in wet H₂S (sour) service and other corrosive refinery environments. nace rp0472 pdf

| Full title | Standard Test Method for Determination of the Effect of Salt‑Water on the Tensile Strength of Coated Steel |
| Sponsor | NACE International (formerly the National Association of Corrosion Engineers) |
| Document type | Recommended Practice (RP) – a technically‑focused guideline, not a regulatory requirement |
| First issue | 1990 (subsequent revisions in 1998, 2005, 2014 and 2020) |
| Primary audience | Corrosion engineers, materials scientists, quality‑control labs, coating manufacturers, oil‑&‑gas operators, naval architects, and anyone involved in assessing the durability of metallic components exposed to seawater. |
| Purpose | Provides a reproducible laboratory method to evaluate how immersion in a saline environment (simulated seawater) influences the tensile properties (yield strength, ultimate tensile strength, elongation, reduction of area) of steel that has been coated with protective systems (e.g., epoxy, polyurethane, zinc‑rich, metallic, or composite coatings). |
| Why it matters | • Corrosion‑related failures are a leading cause of downtime and costly repairs in marine, offshore, and coastal infrastructure.
• Tensile‑strength degradation is a critical design parameter for pipelines, ship hulls, offshore platforms, and offshore wind‑turbine foundations.
• The test method allows manufacturers to qualify coating systems, compare alternative products, and support warranty claims. |
