苏州镀锌方管价格或暂稳观望运行为主厂家心…方管苏州镀锌方管市场价格暂稳。今日上游原材料市场价格、管厂出厂价格均有小幅上涨，近期苏州镀锌方管市场价格暂未调整，整体成交欠佳。据了解，受季节性影响，近期市场活跃度仍 然较低，下游市场需求疲软，客户采购意向弱。方管厂家心态偏悲观，观望情绪浓厚。库存方面持续低位水平运行，按需补货，操作谨慎。整…

方管强度是指焊接方管资料正在静荷作用下抵制毁坏(适量塑性变形或者折断)的功能。因为负荷的作用形式有拉伸、紧缩、蜿蜒、剪切等方式，因为强度也分成抗拉强度、抗压强度、抗弯强度、抗剪强度等。各种强度间常有定然的联络，运用中正常较多以抗拉强度作为最根本的强度表针。

Square tube strength refers to the function of resisting damage (plastic deformation or fracture) of welded square tube data under static load. Because the load acts in the form of tension, contraction, winding, shearing and so on, because the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is always a definite connection between various strengths. Tensile strength is the most basic strength gauge needle in normal use. 【1】焊接方管的功能指数分析-强度 以很大进度作用来机件上的负荷称为冲锋陷阵负荷，焊接方管正在冲锋陷阵负荷作用下抵制毁坏的威力所谓冲锋陷阵韧性。

[1] Functional index analysis of welded square pipe-the load on the machine parts is called the charge-sink-array load because of the great progress of strength. The resistance of welded square pipe to damage under the charge-sink-array load is called the impact-sink-array toughness.

【2】焊接方管的功能指数分析-冲锋陷阵韧性后面所议论的强度、塑性、角度都是金属正在静负荷作用下的机器功能表针。实践上，许多机械整机都是正在重复负荷雇用务的，正在这种环境下整机会发生疲倦。

[2] The strength, plasticity and angle discussed after the toughness of the impact sink array are all the machine function needles of the metal under static load. In practice, many machines are engaged under repeated loads. Under such circumstances, fatigue occurs in the whole machine.

【3】焊接方管的功能指数分析-疲倦罕用的方法有焊接方管布氏角度(HB)、洛氏角度(HRA、HRB、HRC)和维氏角度(HV)等方法。 角度是权衡金属资料软硬水平的表针。眼前生年中内定角度方法最罕用的是压入角度法，它是用定然多少何外形的压头正在定然负荷下压入被测试的金属资料表面，依据被压入水平来内定其角度值。

[3] Functional Index Analysis of Welded Square Pipe - The methods rarely used for fatigue analysis are Brinell Angle (HB), Rockwell Angle (HRA, HRB, HRC) and Vickers Angle (HV) of Welded Square Pipe. Angle is a gauge needle for weighing the hard and soft level of metal data. Pressure angle method is the most rarely used method in the current life. It uses a fixed number of shapes of the pressure head to press into the tested metal data surface under a fixed load, and to determine its angle value according to the level of pressure.

【4】焊接方管的功能指数分析-角度塑性是指焊接方管资料正在负荷作用下，发生塑性变形(永远变形)而不毁坏的威力。

[4] Functional index analysis of welded square pipe-angular plasticity refers to the power of plastic deformation (permanent deformation) without damage of welded square pipe data under load.
