What Are The Characteristics of Large-diameter Steel Pipes

1. Impact toughness of large-diameter steel pipe galvanized square pipe: The load acting on the machine parts at a very high speed is called impact load, and the ability of the metal to resist damage under the impact load is called impact toughness.

2. Strength of large-diameter steel pipe: Strength refers to the ability of metal materials to resist damage (excessive plastic deformation or fracture) under static load. Since the load acts in the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength, etc. There are often corresponding relationships between various strengths. In use, tensile strength is generally used as the more basic strength indicator.

3. Large-diameter steel pipes are divided into seamless and welded seams: Large-diameter steel pipes are made by extruding seamless round pipes.

4. Plasticity of large-diameter steel pipes: Plasticity refers to the ability of metal materials to produce plastic deformation (long-term deformation) without destruction under load.

5. Large-diameter steel pipe fatigue: The strength, plasticity, and hardness discussed previously are all indicators of the mechanical properties of metal under static load. Many machine parts are operated under cyclic loading, and fatigue will occur in the parts under such conditions.

6. Hardness of large-diameter steel pipe: Hardness is a measure of the softness and hardness of metal materials. At present, the commonly used method for measuring hardness in production is the indentation hardness method. It uses an indenter with a corresponding geometric shape to press into the surface of the metal material being tested under a corresponding load, and the hardness value is measured based on the degree of indentation.
