Analysis of the performance index of Lecong square pipe

            Square tube is a kind of square body tube type and material of many kinds of material can form a square body, medium, dry what is used, in what place, most square tube with steel tube for most, square pipe structure, decoration Square, building square.

               The square is a square, called pipe, pipe length is equal. Is the strip through the process of processing volume and become. Generally, the strip is cut down, flat, coiled, welded to form a circular tube, and then rolled into a square tube with a circular tube and cut into the required length. Generally 50 per pack.

             Square seamless and weld points, seamless pipe is extruded into a seamless pipe.

The performance index of 1, the analysis of plastic pipe
Plastic refers to the metal material under the load, resulting in plastic deformation (permanent deformation) and not the ability to destroy.

The performance index of 2, square - hardness analysis
Hardness is a measure of the hardness of the metal material and the pointer. At present the most commonly used method for measuring the hardness of the method is the indentation hardness method, which is used to press the pressure head under certain load to be tested.
Commonly used methods are the method of the hardness, the hardness of the hardness of the and the hardness of the Vivtorinox.

The performance index of 3, the fatigue analysis of square tube
The strength, plasticity and hardness of the preceding discussion are the mechanical properties of the metal under static loading. In fact, many of the machine parts are under the cyclic loading, in which part will produce fatigue.

4, the square performance index analysis of impact toughness
With great speed to load in the parts of the said to impact load, metal under impact load resistance ability damage called impact toughness.

5, the performance index and strength analysis of square
Strength refers to the performance of metal materials under static loading to resist damage (excessive plastic deformation or fracture). Because of the role of the load has a tensile, compression, bending, shear and other forms, so the intensity is also divided into tensile strength, compressive strength, shear strength, etc.. There is a certain connection between the various strength, the use of the general more to the tensile strength as the most basic intensity pointer.
