| The definition of square pipe |
|
Side tube, as its name suggests, it is a physical side of the tube, it is a wide range of materials can be formed of the material side tube, which in the medium, what to use, and where the majority of square tube steel tube in the majority, most of the structure of square tube, square decorative tube, square tube, such as construction.
Square tube, square tube is a name, that is, while the appearance of the steel pipe and so on. After the strip by rolling process. After the general is to strip unpacking, flat, curly, welding tube formation, and then rolled into a tube and then cut into a square tube length needs. Is generally 50 per pack.
Party in possession of a seamless and weld points, seamless square tube is extruded from seamless tube.
1. Side tube analysis of the performance index - plastic
Plasticity refers to the metal material in the load to produce plastic deformation (permanent deformation) without disrupting the ability of.
2. Square Tube performance index analysis - hardness
Hardness is a measure of the degree of soft and hard metal materials pointer. Determination of hardness of the current methods of production of the most commonly used method is the indentation hardness, which is a certain geometry of the pressure head in a certain load to be tested under the pressure of the metal surface, according to the degree of pressure to determine its hardness.
Commonly used methods are Brinell Hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and so on.
3. Side tube analysis of the performance index - fatigue
Discussed in the previous strength, plasticity, hardness is the role of metal under static load in the mechanical properties of pointer. In fact, many machine parts are in working under cyclic loading, in which parts will be under the conditions of fatigue.
4. Side tube analysis of the performance index - the impact toughness
Significant role in the speed of the mechanical load on the load as the impact of metal under impact loading in the destruction of the capacity of resistance is called toughness.
5. Square Tube performance index analysis - strength
Strength refers to metallic materials under static load resistance to damage (excessive plastic deformation or fracture) performance. Because of the way the role of load tensile, compression, bending, shear and other forms, it is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. A certain range of intensity of contact between the frequent use of more generally as a tensile strength of the most basic indicator of the strength. | | | 来源： 时间：2009/7/24 9:14:07 |  |
