These standards, all belong to the US steel standards, such as ASME in the material used by the standards are from ASTM, the valve in the standard reference API, and mild steel pipe fittings from the ANSI standard. The difference lies in the different focus of the industry, so the adoption of different standards. API, ASTM, ASME are members of ANSI. American National Standards Institute standards, the vast majority from the professional standards. On the other hand, the professional associations, associations, groups can also be based on existing national standards to develop certain product standards. Of course, can not follow the national standard to develop their own association standards. ANSI standards are voluntary.
