B/T 8163 is a Chinese national standard suitable for liquid transportation at general temperatures, such as oil, natural gas, and water. There are several types of seamless steel pipes that comply with the GB/T 8163 standard, including:

20 # Carbon Structural Steel: This is a commonly used non alloy steel with a high carbon content in its chemical composition, high strength and hardness, and can meet some general requirements for liquid transportation.

10# Carbon Structural Steel: This is a low-carbon steel with low carbon content in its chemical composition, good plasticity and toughness, suitable for low-pressure liquid transportation.

Q345B low-alloy high-strength structural steel: This is a widely used high-strength steel with a high carbon content in its chemical composition, high tensile strength and yield strength, suitable for high-pressure liquid transportation.

16Mn carbon structural steel: This is a low-alloy high-strength steel with a high carbon content in its chemical composition. It has good strength and toughness and is suitable for medium and high pressure liquid transportation.

It should be noted that the above steel pipe materials are only partial materials that comply with the GB/T 8163 standard. There are other steel pipe materials that comply with this standard, and users can choose according to their actual needs.
