Shinestar steel group Co.,LTD

Carbon steel pipe mainly refers to the carbon quality score is less than 2.11% and does not contain specially added alloy elements of steel, included in the carbon steel level is the most important factor is to affect the strength of steel, hardness increase, and reduce ductility, toughness and welding capacity. In addition to carbon, it usually contains small amounts of silicon, manganese, sulfur and phosphorus. Compared with other types of steel, it is the earliest, low cost, wide range of performance, the largest amount of steel. It is suitable for water, steam, air, hydrogen, ammonia, nitrogen and petroleum products at a nominal pressure PN of 32.0MPa, temperature -30-425 degrees C. Steel pipe is the earliest basic material to be used most in modern industry. While the world's industrial countries are striving to increase the production of high-strength, low-alloy steel and alloy steel, they also pay great attention to improving quality, expanding the variety and use of the range. It is not only widely used in buildings, bridges, railways, vehicles, ships and various machinery manufacturing industry, but also in the modern petrochemical, marine development and other industries, but also a large number of applications. Carbon steel pipes are used to transport oil, gas and other fluids.
