Square tube is kind of square body, many kinds of material can form a square body, it is medium in, what, in what place, most square to steel for the majority, for the structure of square, square building decoration,square and so on.
The square is a square, called pipes, is equal to the length of steel pipe. After the process of strip is rolled. The general is to strip after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into squaretube and then cut into required length. The average is 50 per package.
Square seamless and weld points, seamless pipe is extruded into a seamless pipe.
The performance index of 1 square - plastic analysis
Plastic refers to the metal material under load, plastic deformation (permanent deformation) without destroyingthe ability.
The performance index of 2 square - hardness analysis
Hardness is a measure of the pointer degree of soft metal materials. In the current production of hardness testing method is the most commonly used method of indentation hardness, it is with a certain pressure headgeometry under load is pressed into the metal surface to be tested, according to the degree to be pressed into the determination of the hardness.
The commonly used method of Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vivtorinox(HV) hardness method.
The performance index of 3 square - fatigue analysis
The strength, plasticity, hardness and mechanical properties of the metal pointer is under static load. In fact,many of the machine parts are working under cyclic loading conditions, in this part will produce fatigue.
Analysis of performance index of 4 square impact toughness
With great speed to load the parts called the impact load, the metal against damage under impact load is called impact toughness.
Analysis of performance index of the 5 square pipe strength
Strength refers to the metal material damage resistance under static loading condition (excessive plastic deformation or fracture) performance. Because of the effects of the way of load tensile, compression, bending,shear and other forms, so the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength. Often there is some relationship between the use of various strength, generally totensile strength as the strength of the most basic pointer.
