如何辨别镀锌管的材质和质量?

来源:http://www.jnlhjscl.com/ 日期:2020-06-11 发布人:adminlehao

  我们知道现代社会装修的原材料很多,其中镀锌管作为一种能够有效提高钢管耐腐蚀性的产品,它在工业生产当中发挥出了突出的优势,并且为满足不同用户的需求而进行了不断的完善和改进,从而为作为用户的我们提供了有保障的服务。下面济南镀锌管的小编就为您带来镀锌钢管的材质,镀锌管质量如何鉴别希望可以帮助大家认识

  We know that there are many raw materials for decoration in modern society, among which galvanized pipe, as a product that can effectively improve the corrosion resistance of steel pipe, has played an outstanding advantage in industrial production, and has been continuously improved and perfected to meet the needs of different users, thus providing us as users with guaranteed services. The following small braid of Jinan galvanized steel pipe will bring you the material of galvanized steel pipe. How to identify the quality of galvanized steel pipe is hoped to help you understand
  镀锌钢管的材质?
  Material of galvanized steel pipe?
  1、低碳:由于韧性、焊接性和冷成形性能的要求高,其碳含量不超过0.20%。
  1. Low carbon: due to the high requirements of toughness, weldability and cold forming performance, the carbon content shall not exceed 0.20%.
  2、加入以锰为主的合金元素。
  2. The main alloy element is manganese.
  3、加入铌、钛或钒等辅加元素:少量的铌、钛或钒在钢中形成细碳化物或碳氮化物,有利于获得细小的铁素体晶粒和提高钢的强度和韧性。此外,加入少量铜(≤0.4%)和磷(0.1%左右)等,可提高抗腐蚀性能。加入少量稀土元素,可以脱硫、去气,使钢材净化,改善韧性和工艺性能。
  3. The addition of Nb, Ti or V: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel. In addition, adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can remove sulfur and gas, purify steel, improve toughness and process performance.
  4、元拓热镀锌钢管具有镀层均匀、附着力强、使用寿命长等优点。热镀锌钢管基体与熔融镀液发生复杂的物理及化学反应,形成耐腐蚀且结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体,其耐腐蚀性能强。
  4. YUANTUO hot-dip galvanized steel pipe has the advantages of uniform coating, strong adhesion and long service life. The complex physical and chemical reactions between the hot-dip galvanized steel pipe matrix and the molten bath form a zinc iron alloy layer with corrosion resistance and tight structure. The alloy layer is integrated with pure zinc layer and steel pipe matrix, which has strong corrosion resistance.
  镀锌管质量如何鉴别?
  How to identify the quality of galvanized pipe?
  1、镀锌钢管的牌号和化学成份,在设计制作的过程中,镀锌钢管所用钢的牌号与化学成分应该符合GB-3092中所规定的黑管用钢的牌号和化学成份要求。
  1. The brand and chemical composition of galvanized steel pipe. In the process of design and manufacture, the brand and chemical composition of steel used for galvanized steel pipe shall meet the brand and chemical composition requirements of black pipe steel specified in gb-3092.
  2、镀锌钢管的制造方法选择,制造厂选择制造黑管的制造方法,镀锌时应该采用热浸镀锌法。
  2. The manufacturing method of galvanized steel pipe shall be selected. The manufacturer shall select the manufacturing method of black pipe. The hot-dip galvanizing method shall be adopted when galvanizing.

  3、镀锌钢管的螺纹及管接(一般的客厅都会使用这种)
  3. Galvanized steel pipe thread and pipe connection (common living room will use this)
  (1)带螺纹交货的镀锌钢管,螺纹应在镀锌后车制。螺纹必须符合YB822的规定。
  (1) For galvanized steel pipes delivered with thread, the thread shall be machined after galvanizing. The thread must comply with yb822.
  (2)钢制管接头必须符合YB238的规定,可铸铁管接头必须符合YB230的规定。
  (2) The steel pipe joint must conform to the regulations of yb238, and the cast iron pipe joint must conform to the regulations of yb230.
  4、镀锌钢管力学性能与镀锌层重量,镀锌前的钢管力学性能应符合GB3092的规定。镀锌层重量应不小于500g/㎡。
  4. The mechanical properties of galvanized steel pipe and the weight of galvanized layer, and the mechanical properties of steel pipe before galvanizing shall conform to the provisions of gb3092. The weight of galvanized layer shall not be less than 500g / ㎡.
  5、镀锌层的均匀性与冷弯曲试验,钢管试样在硫酸铜溶液中连续浸渍5次不得变红。口径不大于50mm的镀锌钢管应做冷弯曲试验。弯曲角度为90度。
  5. For the uniformity and cold bending test of the galvanized layer, the steel pipe sample shall not turn red after being immersed in copper sulfate solution for 5 times. The galvanized steel pipe with diameter no more than 50mm shall be subject to cold bending test. The bending angle is 90 degrees.
  6、镀锌钢管水压试验与表面质量,试验压力及涡流探伤对比试样尺寸应符合国标GB3092的规定。 镀锌钢管的表面应该有完整层,不得有未镀上锌的黑斑和气泡存在。允许有不大的粗糙面和局部的锌瘤存在。
  6. The hydrostatic test, surface quality, test pressure and eddy current test of galvanized steel pipe shall conform to the provisions of GB 3092. The surface of galvanized steel pipe shall have a complete layer, and there shall be no black spots and bubbles without zinc plating. Small rough surface and local zinc tumor are allowed.
  镀锌管,我们又称为镀锌钢管,分为热镀锌和电镀锌两种。其中热镀锌镀锌层厚,具有镀层均匀,附着力强,使用寿命长等优点。而电镀锌成本低,表面不是很光滑,其本身的耐腐蚀性比热镀锌管差很多。以上就是镀锌钢管的材质,镀锌管质量鉴别的详细介绍,由济南镀锌管提供,想要了解更多欢迎咨询http://www.jnlhjscl.com网站。
  Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro galvanizing. Among them, the hot-dip galvanizing zinc coating has the advantages of uniform coating, strong adhesion and long service life. The cost of galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe. The above is the material of galvanized steel pipe, the detailed introduction of quality identification of galvanized pipe, provided by Jinan galvanized pipe, for more information, please consult http://www.jnlhjscl.com Website.
