Carbon seamless steel pipe refers to a pipe made of carbon steel without any welded joints or seams, and a solid billet is extruded through a die to form a pipe of the desired shape and size. Carbon seamless steel pipe is popular for its outstanding durability, tensile strength and corrosion resistance, making it ideal for a wide range of industries including oil and gas, automotive and construction.
One of the most popular grades of carbon seamless steel pipe is A106 Grade B, which is the ASTM standard for seamless carbon steel pipe for high temperature service. It has a maximum carbon content of 0.30%, making it ideal for applications requiring high temperature and pressure. It is also suitable for low pressure and low temperature applications, as well as welding and brazing.
Another popular grade is API 5L Grade B, which is the standard for seamless and welded steel pipe for pipeline transmission systems in the oil and gas industry. It has a maximum carbon content of 0.30%, making it ideal for use in high pressure and high temperature service environments.
In addition to the grade, the material of the carbon seamless steel pipe is also very important. Common materials include SAE 1020, which has a low carbon content and is ideal for bending, flanging and similar forming operations, and SAE 1045, which has a higher carbon content and is ideal for applications requiring hardness, toughness and resistance to wear.
Other materials include ASTM A519 Grade 4130 for high-pressure hydraulic lines and oilfield tubing, and ASTM A106 Grade C with a maximum carbon content of 0.35% for applications requiring high corrosion resistance.
In conclusion, carbon seamless steel pipes are essential in a wide range of industries and the choice of grade and material depends on the specific application. A106 Grade B and API 5L Grade B are popular grades, while materials such as SAE 1020, SAE 1045, ASTM A519 Grade 4130, and ASTM A106 Grade C are popular choices.
