When searching for the , engineers often look for the historical "Recommended Practice" (RP). In the mid-2000s, NACE systematically transitioned its nomenclature from "RP" to "SP" (Standard Practice) .

It is important to note that the practices recommended in NACE RP0472 are intended to avoid in-service cracking and are not intended to address cracking that can occur during fabrication, such as delayed hydrogen cracking. In most cases, however, these practices are also helpful in minimizing these fabrication problems. nace rp0472 pdf

The standard was developed to combat a specific type of failure known as "environmental cracking." Most petroleum refining equipment is made of carbon steel with a minimum specified tensile strength of up to 480 MPa (70,000 psi), and welding is the primary fabrication method. Failures in these welds, often documented in NACE publications, can lead to dangerous safety incidents, expensive mechanical repairs, and substantial production losses. The industry recognized a need for a unified, consensus-based method to minimize the risk of such failures. In most cases, however, these practices are also

NACE SP0472 (formerly RP0472) provides the industry-standard "Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments." Key Takeaways for Engineers & Inspectors: Target Hardness:

The standard focuses primarily on downstream refining environments where hydrogen blistering, Hydrogen-Induced Cracking (HIC), and Stress Oriented Hydrogen-Induced Cracking (SOHIC) are common risks.

Confusion often arises regarding which NACE standard to apply. The following breakdown clarifies their distinct applications: Scope / Focus Primary Industry Sector
