- ASTM, ANSI, ASME and API Standards Introduction and Difference
- ASTM: American Society for Testing and Materials (American Society for Testing and Materials) - Materials
- ANSI: American National Standards Institute (AMERICAN NATIONAL STANDARDS INSTITUTE) - Fittings
- ASME: American Society of Mechanical Engineers (American Society of Mechanical Engineers)
- API: American Petroleum Institute (American Petroleum Institute) - Valve
- The above four standards are U.S. standards, these four standards complement each other, drawing on each other, such as ASME in the material aspects of the standards adopted by the ASTM, in the valve aspects of the standards draw on API, and pipe fittings standards are from ANSI. The difference lies in the different focus of the industry, so the standards adopted are different, API, ASTM, ASME are members of ANSI.
