    Study Notes

    API Welding Standards and Publications

    • API publications aim to make engineering and operating practices widely available and do not replace the need for sound engineering judgment.
    • Manufacturers must comply with API standards when marking equipment, but API does not guarantee conformance.
    • Classified areas may differ based on location, conditions, equipment, and substances, and users should consult appropriate authorities.
    • The standard was developed by a committee including API, AGA, PLCA, AWS, ASNT, pipe manufacturers, and related industry representatives.
    • Its voluntary purpose is to guide the production of high-quality welds and inspection methods for new construction and in-service welding.
    • The standard applies to welding of piping used in the compression, pumping, and transmission of crude petroleum, petroleum products, fuel gases, carbon dioxide, and nitrogen.
    • API standards do not grant rights for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent.
    • The use of "shall" in the standard denotes a minimum requirement, while "should" denotes a recommendation but not a requirement.
    • API standards are reviewed, revised, reaffirmed, or withdrawn every five years, with a possible two-year extension.
    • The document was produced under API standardization procedures and is designated as an API standard.
    • Questions and requests for permission should be directed to the Director of Standards at the American Petroleum Institute.
    • The standard covers scope, normative references, terms and definitions, specifications, equipment, materials, qualification of welding procedures, and inspection and testing of production welds.

    Welding and NDT Standards Summary

    • The document contains detailed standards for Non-Destructive Testing (NDT) personnel certification and acceptance criteria for various NDT methods such as Radiographic, Magnetic Particle, Liquid Penetrant, and Ultrasonic Testing.
    • It also includes guidelines for repair and removal of weld defects, including authorization for repair, repair procedures, and acceptance criteria.
    • The procedures for NDT are outlined, including specific methods for Radiographic, Magnetic Particle, Liquid Penetrant, and Ultrasonic Testing.
    • Mechanized welding with filler metal additions is covered, including acceptable processes, procedure qualification, essential variables, and inspection standards for production welds.
    • Automatic welding without filler metal additions is also detailed, including acceptable processes, procedure qualification, and quality assurance of production welds.
    • The document includes alternative acceptance standards for girth welds and in-service welding, as well as a process for requesting interpretation and revision.
    • Various figures and tables are provided, showing sample forms, test reports, test specimens, imperfections, and macro test specimens for in-service welds.
    • The figures include sample welding procedure specification forms, location of test specimens, and examples of typical temper bead deposition sequences.
    • Tables provide information on filler metal groups, types and numbers of test specimens, and maximum dimensions of undercutting.
    • The document also includes detailed illustrations of various test specimens, such as tension test, nick break test, and macro test specimens for in-service welds.
    • It covers various imperfection limits for CTOD testing and criteria for evaluation of imperfection interaction.
    • The document also provides suggested locations of test specimens for sleeve and branch welds, reinforcing pads, saddles, and sleeves.
