NACE RP0472 (now ANSI/AMPP SP0472) is the primary industry standard for preventing environmental cracking in carbon steel weldments within corrosive petroleum refining environments. Overview of the Standard The standard, titled

"Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Refining Environments,"

establishes the minimum requirements for welding procedures, hardness testing, and post-weld heat treatment (PWHT). Its goal is to ensure that weldments are resistant to common refining industry issues like Stress Corrosion Cracking (SCC) Hydrogen-Induced Cracking (HIC) 1. Scope and Application Target Materials: Specifically covers P-No. 1 carbon steels (the most common structural and pressure vessel steels). Environment: You're looking for information related to NACE RP0472,

Focuses on refining processes involving corrosive agents such as hydrogen sulfide ( cap H sub 2 cap S ), hydrofluoric acid ( cap H cap F ), and amines. Weld Zones:

Addresses the weld metal, the Heat-Affected Zone (HAZ), and the adjacent base metal. 2. Key Prevention Strategies

The standard outlines three critical control methods to maintain the integrity of the steel: Hardness Control:

High hardness is a primary indicator of susceptibility to cracking. The standard typically mandates a maximum hardness of 200 Brinell (HBW) for the weld deposit. Post-Weld Heat Treatment (PWHT):

PWHT is often required to reduce residual stresses from welding and to temper the microstructure, thereby lowering the hardness of the HAZ. Welding Procedure Qualification:

Procedures must be tested and qualified to ensure they consistently produce welds that meet the hardness and ductility requirements. 3. Hardness Testing Requirements Updated Edition : NACE periodically updates its standards,

To verify compliance, the standard specifies rigorous testing protocols: Frequency:

Regular testing intervals on production welds (e.g., one test per every 15 meters of weld).

Testing must be performed on the process-side (the side exposed to the corrosive medium) whenever possible. Methodology:

Guidance is provided on using portable hardness testers and converting values (e.g., Rockwell C to Brinell) accurately. 4. Transition to AMPP

Users looking for the "new" PDF should note that NACE International merged with SSPC to form

AMPP (The Association for Materials Protection and Performance) . Consequently, the document is now designated as ANSI/AMPP SP0472

Here’s a draft feature / content brief for a piece (blog post, product page, or tool tip) focused on “NACE RP0472 PDF new” — i.e., the latest version of NACE RP0472 (now often numbered RP0472-202X).

4. Filler and Shim Installation (Major Update in the New Version)

• Old standard allowed organic felt pads—now prohibited due to wicking.
• Required: Closed-cell polymer shims with a compressive strength >50 MPa.
• The PDF includes a new Table 3 listing approved shim materials and their load ratings.
