Rectangular pipes
, as the name suggests, it is a rectangular tube shape, and many materials can be used to form rectangular pipes. Body, its medium, what is it used for, and where is it used? Most rectangular tubes are mostly steel tubes, mostly structural rectangular tubes, decorative rectangular tubes, architectural rectangular tubes, etc.
Rectangular tubes are a type of rectangular tubes The name refers to the strip steel rolled through process treatment. Generally, the strip steel is unpacked, flattened, curled, and welded into a round tube, which is then rolled into a rectangular tube and then cut to the required length. Usually one root per package.
Rectangular tubes can be divided into seamless and welded seams. Seamless rectangular tubes are made by extruding seamless round tubes.
Analysis of plasticity of performance index of shaped pipe
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without destruction under the action of load.
Performance Index Analysis of Rectangular Pipe Hardness
Hardness is a measure of the softness and hardness of metal materials. At present, the most commonly used method for measuring hardness in production is the indentation hardness method, which uses an indenter of a certain geometric shape to press into the surface of the metal material being tested under a certain load, and the hardness value is measured based on the degree of indentation.
Commonly used methods include Brinell hardness, Rockwell hardness and Vickers hardness.
Fatigue analysis of performance index of rectangular tube
The strength, plasticity and hardness discussed above are all mechanical performance indicators of metal under static load. In fact, many machine parts are operated under cyclic loading, and fatigue will occur in the parts under such conditions.
Performance Index Analysis of Rectangular Pipes Impact Toughness
The load acting on the machine parts at a very high speed is called impact load, and the ability of metal to resist damage under the action of impact load is called impact toughness.
Performance index analysis strength of rectangular tube
Strength refers to the performance of metal materials against damage (excessive plastic deformation or fracture) under static load. Because the load acts in the form of tension, compression, bending, shear, etc., strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc. There is often a certain relationship between various strengths. In use, tensile strength is generally used as the most basic strength indicator.
