Carbon steel pipe & tube is an important steel pipe. It has been widely used in industrial production due to its wide range of uses, such as oil pipes, water pipes, gas pipes, etc. Carbon steel pipes have good mechanical properties such as pressure testing, bending, twisting, and stretching, and have the characteristics of high strength and corrosion resistance. Due to its good comprehensive performance, carbon steel pipes have been highly recognized by the market.
International standards:
1. ASTM standard: Steel pipe standard formulated by the American Society for Testing and Materials, applicable to pipes and equipment under various temperatures and pressures.
2. DIN standard: Standard formulated by the German Industrial Standardization Committee, applicable to pipelines and equipment in high-pressure, high-temperature and low-temperature environments.
3. EN standards: Standards formulated by the European Organization for Standardization, applicable to various steel pipes and equipment in the European market.
4. GB standard: Standard formulated by the National Standardization Administration Committee, applicable to pipelines and equipment in construction, shipbuilding, machinery, chemical industry and other fields.
5. JB standard: Standard formulated by the Machinery Industry Standardization Committee, applicable to pipelines and equipment in the machinery industry, metallurgical industry and other fields.
Implementation standards for carbon steel pipes:
1. American standards:
ASTM A106,
ASTM A53, API 5L
2. Japanese standards: JIS G3444, JIS G3454, JIS G3455, JIS G3456, JIS G3457, JIS G3461
