热镀锌管的特点有哪些?

  热镀锌管的制造是先将钢管进行酸洗,用来去除钢管表面的氧化铁,酸洗后,通过氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗,然后送入热浸镀槽中。这都是很多的镀锌管厂家所运用的方法。热镀锌钢管是钢管基体与熔融的镀液发生复杂的物理、化学反应,形成耐腐蚀的结构紧密的锌铁合金层。合金层与纯锌层、钢管基体融为一体,这样热镀锌钢管也有很好的附着力、均匀的镀层,使用的寿命也延长了很多,这些也都是热镀锌管的优点。

  Hot-dip galvanized pipes are manufactured by pickling the steel pipes to remove iron oxide on the surface of the pipes. After pickling, the pipes are cleaned through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot-dip galvanized tank. These are the methods used by many galvanized pipe manufacturers. Hot-dip galvanized steel pipe is a kind of zinc-iron alloy layer with corrosion-resistant structure, which is formed by complex physical and chemical reaction between the steel pipe matrix and the molten plating solution. Alloy layer is integrated with pure zinc layer and steel tube matrix, so hot-dip galvanized steel pipe also has good adhesion, uniform coating and prolonged service life. These are also the advantages of hot-dip galvanized steel pipe.

  镀锌管的力学性特点

  Mechanical Characteristics of Galvanized Pipe

  钢材力学能使保证钢材最终是用性能的一种重要标指标。在钢管标准中,根据不同的使用要求,规定了拉伸性能以及硬度和韧性的指标,还有一些用于作要求的高、低温性能等等。

  Steel mechanics is an important criterion to ensure the ultimate performance of steel. In the steel pipe standard, according to different application requirements, the indexes of tensile properties, hardness and toughness are stipulated, and some of them are used for high and low temperature properties.

  镀锌管镀层的均匀性

  Uniformity of Galvanized Tube Coating

  镀锌钢管试验在硫酸铜溶液中连续浸泡5次不得变红(呈镀铜色),这样的镀锌管镀锌层是均匀的。

  The galvanized steel pipes are immersed in copper sulphate solution for five consecutive times without turning red (copper-plated). The galvanized layer of the galvanized steel pipes is uniform.

  镀锌管的规格尺寸

  Specification and Dimension of Galvanized Pipe

  公称壁厚(mm):2.0 2.5 2.8 3.2 3.5 3.8 4.0 4.5

  Nominal wall thickness (mm): 2.02.52.8 3.23.53.8 4.04.5

  重量系数c:1.064 1.051 1.045 1.040 1.036 1.034 1.032 1.028

  Weight coefficient c: 1.064 1.051 1.045 1.040 1.036 1.034 1.032 1.028

  由于市场的不稳定,镀锌管价格在某些方面也会受到一定的影响,所以用户们也不用太过于担心,这是一个比较正常的现象。

  Because of the unstable market, the price of galvanized pipe will be affected in some aspects, so users need not worry too much, this is a relatively normal phenomenon.
