WASHINGTON, May 5, 2025 — The American Petroleum Institute (API) is pleased to announce the publication of an Addendum to the 11th edition of the API 5CT, Casing and Tubing. The update strengthens the requirements for the manufacture of steel casing and tubing used in oil and gas drilling and production operations, enhancing safety, environmental protection and operational integrity.
In December 2020, American Petroleum Institute (API) published Recommended Practice 1183, First Edition (RP 1183), Assessment and Management of Dents in Pipelines. Since being issued, RP 1183 has been applied by pipeline operating companies and engineering consultants providing services to the energy pipeline industry to evaluate dents and deformations on pipeline systems and to support mitigation and repair decisions. RP 1183 includes various screening tools to estimate the remaining fatigue life of a dent in a pipeline.
February 4, 2025 – The American Petroleum Institute (API) today released a new report, 2025 API StandardsInternational Usage Report, detailing the growing international influence of API standards. The report identifies where governments and standards bodies reference API standards in policies, national and international standards, and technical regulations, highlighting the paramount role of API standards in advancing safety, sustainability, and efficiency across the global natural gas and oil industry.
The American Petroleum Institute (API) is pleased to announce the release of the second edition of API Standard 20S, Qualification of Metal Additive Manufacturing Processes and Components Production Control for Use in the Petroleum and Natural Gas Industries.
