The American Petroleum Institute (API) develops and maintains standards that ensure safety, reliability, and environmental protection across the oil and gas industry. From API 510 (pressure vessel inspection) to API 1104 (pipeline welding), these standards establish minimum requirements for equipment design, fabrication, and maintenance.

Compliance with API standards is often contractually required and demonstrates commitment to industry best practices. This tag explores specific API requirements, implementation strategies, and how these standards intersect with ASME codes and other regulatory frameworks in energy and petrochemical applications.
