What Is The Compressive Strength of Carbon Steel Pipe?

The compressive strength of carbon steel pipe varies according to specifications and wall thickness. Common carbon steel pipe pressure grades include PN6, PN10, PN16, etc., indicating different rated pressures. Taking DN15 (1/2 inch) carbon steel pipe as an example, its compressive strength can reach 26.2MPa, which belongs to the PN16 pressure grade. The specific compressive strength needs to be determined according to actual needs and product specifications.

Overview of compressive strength of carbon steel pipe

As a widely used pipe material, the compressive strength of carbon steel pipe is an important indicator for evaluating its quality and performance. Compressive strength refers to the ability of the pipe to withstand internal pressure without rupture or deformation. The compressive strength of carbon steel pipe varies depending on factors such as pipe specifications, wall thickness, and production process. Therefore, when selecting carbon steel pipe, its compressive strength must be clearly determined to meet specific application requirements.

Classification of carbon steel pipe pressure grades

For ease of selection and application, carbon steel pipes are divided into different pressure grades according to their compressive strength. Common carbon steel pipe pressure grades include PN6, PN10, PN16, PN25, PN40, etc., where "PN" represents the rated pressure. These pressure grades correspond to different pressure ranges. For example, PN16 represents a rated pressure of 16Bar, or 1.6MPa.

Calculation of the compressive strength of carbon steel pipes

The compressive strength of carbon steel pipes can be calculated using relevant formulas, which involve parameters such as the nominal size of the pipe, wall thickness, and tensile strength of the material. Taking the commonly used DN15 (1/2 inch) carbon steel pipe as an example, assuming that its nominal wall thickness is 2.11mm, the tensile strength of the material is 410MPa, and the temperature coefficient is 0.8, the formula P=2ST/D is used to calculate that the compressive strength of the carbon steel pipe is 26.2MPa, which belongs to the PN16 pressure grade.

How to choose the appropriate carbon steel pipe pressure grade

When selecting a carbon steel pipe, in addition to considering its compressive strength, it is also necessary to comprehensively consider factors such as the use environment, system pressure, and medium properties. First, determine the required pressure level according to the working pressure of the system; second, select the appropriate pipe material according to the corrosiveness, temperature and other properties of the medium; finally, determine the specifications and wall thickness of the pipeline based on actual needs.

Summary

In short, understanding the compressive strength and pressure level of carbon steel pipes is of great significance for the correct selection and use of carbon steel pipes. By reasonably selecting the pressure level, it can be ensured that the pipeline can withstand the expected pressure during use, thereby ensuring the safe and stable operation of the system.
