Carbon seamless steel pipes are made of carbon steel, alloy steel, stainless steel ingots or solid tube blanks, and are made by hot rolling, cold rolling or cold drawing. Because they are manufactured from a solid billet of steel with no welds, they have inherent mechanical strength. Today, we will discuss how to check the physical properties of seamless carbon steel pipes.
To check whether the physical properties of seamless carbon steel pipes meet the requirements, you need to refer to relevant standards and specifications, as follows:
1. Tensile test
By conducting tensile tests on seamless steel pipes, its physical performance indicators such as tensile strength, yield strength and elongation can be measured. The inspection results should be compared with the requirements in the standard specifications to determine whether the physical properties of the seamless steel pipe meet the standard requirements.
2. Impact test
By conducting impact tests on seamless steel pipes, its toughness and impact resistance can be determined. The inspection results should be compared with the requirements in the standard specifications to determine whether the physical properties of the seamless steel pipe meet the standard requirements.
3. Hardness test
By conducting hardness tests on seamless steel pipes, their hardness values can be determined. The inspection results should be compared with the requirements in the standard specifications to determine whether the physical properties of the seamless steel pipe meet the standard requirements.
4. Dimensional inspection
By measuring the diameter, thickness, length and other dimensions of seamless steel pipes, you can determine whether they meet the standard requirements. The inspection results should be compared with the requirements in the standard specifications to determine whether the physical properties of the seamless steel pipe meet the standard requirements.
5. Appearance inspection
By inspecting the surface of seamless steel pipes, you can determine whether there are defects, bubbles, cracks and other problems on the surface. The inspection results should be compared with the requirements in the standard specifications to determine whether the physical properties of the seamless steel pipe meet the standard requirements.
