方管是种方形体的管型,很多种材质的物质都可以形成方管体,它介质于,干什么用,用在什么地方,大多数方管以钢管为多数,多为结构方管,装饰方管,建筑方管等.

Square pipe is a kind of square pipe. Many kinds of material can form square pipe. It's medium, what's it used, where is it used. Most square pipe is made of steel pipe, mostly structural square pipe, decorative square pipe, building square pipe and so on.

方管,是方形管材的一种称呼,也就是边长相等的的钢管。是带钢经过工艺处理卷制而成。一般是把带钢经过拆包,平整,卷曲,焊接形成圆管,再由圆管轧制成方形管然后剪切成需要长度。一般是50根每包。

Square pipe is a form of address for square pipe, that is, steel pipe with equal side length. The strip is coiled by process treatment. Generally, strip steel is unpacked, flattened, coiled, welded to form a circular pipe, then rolled into a square pipe from the circular pipe and cut into the required length. Usually 50 pieces per bag.

方管有无缝和焊缝之分,无缝方管是将无缝圆管挤压成型而成。

Square pipe can be divided into seamless and welded seams. Seamless square pipe is formed by extrusion of seamless round pipe.

1. 方管的性能指数分析-塑性

塑性是指金属材料在载荷作用下,产生塑性变形(变形)而不破坏的能力。

Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without destroying under load.

2. 方管的性能指数分析-硬度

2. Performance Index Analysis of Square Tube-Hardness

硬度是衡量金属材料软硬程度的指针。目前生产中测定硬度方法比较常用的是压入硬度法,它是用一定几何形状的压头在一定载荷下压入被测试的金属材料表面,根据被压入程度来测定其硬度值。

Hardness is the index to measure the degree of hardness and softness of metal materials. Pressure hardness method is the most commonly used method to measure hardness in production at present. It uses a certain geometric shape of the pressure head to press into the tested metal material surface under a certain load, and to measure its hardness value according to the degree of pressure.

常用的方法有布氏硬度(HB)、洛氏硬度(HRA、HRB、HRC)和维氏硬度(HV)等方法。

Common methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).

3. 方管的性能指数分析-疲劳

3. Performance Index Analysis of Square Pipe-Fatigue

前面所讨论的强度、塑性、硬度都是金属在静载荷作用下的机械性能指针。实际上,许多机器零件都是在循环载荷下工作的,在这种条件下零件会产生疲劳。

The strength, plasticity and hardness discussed above are all mechanical performance indicators of metals under static loads. In fact, many machine parts work under cyclic loads, under which fatigue occurs.

4. 方管的性能指数分析-冲击韧性

4. Performance Index Analysis of Square Tube-Impact Toughness

以很大速度作用于机件上的载荷称为冲击载荷,金属在冲击载荷作用下抵抗破坏的能力叫做冲击韧性。

The load acting on the machine parts at a great speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.

5. 方管的性能指数分析-强度

5. Performance Index Analysis of Square Pipe - Strength

强度是指金属材料在静荷作用下抵抗破坏(过量塑性变形或断裂)的性能。由于载荷的作用方式有拉伸、压缩、弯曲、剪切等形式,所以强度也分为抗拉强度、抗压强度、抗弯强度、抗剪强度等。各种强度间常有一定的联系,使用中一般较多以抗拉强度作为比较基本的强度指针。

Strength refers to the resistance of metal materials to failure (excessive plastic deformation or fracture) under static load. Because the load acts in the form of tension, compression, bending and shearing, the strength can also be divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is always a certain relationship between various strengths. Tensile strength is usually used as the most basic strength indicator.
