The seamless steel pipe widely used in the world is a high-quality pipe and is widely used in industry, chemical industry, construction and other fields. Seamless steel pipes are favored by the industry due to their high strength, corrosion resistance, and high temperature resistance. There are also corresponding standards in terms of specifications and wall thickness. The following is a list of international seamless steel pipe specifications and wall thickness standards:
Specifications:
1. American standards: ASTM A106, ASTM A53, API 5L, ASTM A192, ASTM A210, ASTM A213, etc.;
2. Japanese standards: JIS G3454, JIS G3455, JIS G3456, JIS G3461, JIS G3462, etc.;
3. German standards: DIN 1626, DIN 17175, DIN 2448, DIN 2391, etc.;
4. British standards: BS 1387, BS 3601, BS 3059, BS 6323, etc.;
