Standard numbers, names and grades of steel pipes commonly used in Japan JISG3429-88 - Seamless steel pipes for high-pressure gas containers - STH11, STH12, STH21, STH22, STH31 JISG3452-97 - Carbon steel pipes for piping - SGP JISG3454-88 - Carbon steel pipes for pressure pipes - STPG370, STPG410 JISG3459-97 - Stainless steel pipes for piping - SUS304TP, SUS304HTP, SUS304LTP, SUS309TP, SUS309STP, SUS310TP, SUS310STP, SUS316TP, SUS317TP. How are they related to Chinese steel pipes?
The standards for materials implemented in different countries are different. Strictly speaking, these brands are not related. However, similar materials can also be found in various standards regarding their characteristics and uses. You can find a comparison table of Chinese and foreign steel numbers online to compare them one by one. But this is just a reference. For example, the ASME standard requires that the nickel content of 316L is 10-14%, while the national standard requires 12-15%.
Agree with the comments above. At present, there are no unified standards in various countries. Various material properties and specifications cannot be completely matched. However, similar materials can still be found under various internationally accepted standards.
At present, domestic and foreign pipeline standards can basically be divided into two series, the American system and the European system. The American series represented by ASME B16.5 and the European series represented by DIN2401 currently have great influence in different regions of the world and cannot be unified into one standard. The international standards organization developed ISO, which is a compromise standard that is compatible with both standards. Japan's JIS standard is neither American nor European. In order to make up for this shortcoming, the Japan Petroleum Association compiled the JPI standard. The basic equivalence adopts the ASME/API application standard and is interchangeable with ASME.
Thank you very much, useful post!
