Material Standard
Material standards for steel are usually formulated by international organizations, national standardization institutions and industry associations. The following are some common steel material standards:
International Standards: Mainly formulated by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
American standards: mainly formulated by the American Standards Institute (ANSI) and the American Iron and Steel Institute (AISI).
European standards: mainly formulated by the European Committee for Standardization (CEN) and the European Iron and Steel Association (Eurofer).
Japanese standards: mainly formulated by the Japanese Industrial Standardization Organization (JIS).
In addition to the above common standards, there are many standards formulated by other countries and regions, such as China’s GB/T standard, Canada’s CSA standard, etc. Different standards of steel are different in chemical composition, mechanical properties, processing technology, etc., so it needs to be selected according to specific needs when selecting and using.

Production Standards
Flange production standards usually refer to the production standards of steel flanges. Steel flange is a common pipeline connection component used to connect pipelines, valves, pumps and other equipment. The following are some common steel flange production standards:
ANSI standards: Standards formulated by the American National Standards Institute, including ANSI B16.5, ANSI B16.47, etc.
DIN standards: Standards formulated by the German National Organization for Standardization, including DIN 2573, DIN 2576, DIN 2631, DIN 2632, etc.
JIS Standards: Standards formulated by Japanese Industrial Standards, including JIS B2220, JIS B2291, etc.
BS Standards: Standards formulated by British Standards, including BS 4504, BS 10, etc.
These standards usually include flange size, material, pressure level, surface treatment, connection method and other requirements. When producing steel flanges, it is necessary to select appropriate production standards according to specific application scenarios and requirements. If customers have special needs, welcome to submit drawings and customize flanges.
