  镀锌管在钢铁行业中深入人心,深受大家的喜爱,但我们在采购镀锌管时,还必须掌握一些产品的优缺点的技巧,帮助我们在采购时选择钢材的质量。

  Galvanized pipe is popular in the iron and steel industry and deeply loved by everyone. However, when we purchase galvanized pipe, we must master the advantages and disadvantages of some products to help us choose the quality of steel when we purchase.

  1. 假镀锌管容易划伤,原因是假镀锌管厂家设备简单,容易产生毛刺,划伤钢材表面。深度划痕降低了钢的强度。

  1. The fake galvanized pipe is easy to be scratched, because the equipment of the fake galvanized pipe manufacturer is simple and easy to produce burrs and scratch the steel surface. Deep scratches reduce the strength of the steel.

  2.劣质镀锌管无金属光泽,呈淡红色或类似生铁。

  2. The poor galvanized pipe has no metallic luster and is light red or similar to pig iron.

  3.的单杠下镀锌管薄,低,经常出现填不满的现象,原因是制造商为了达到大负公差,成品前几的压力太大,铁太小,填补这个洞的不满。

  3. The galvanized pipe under the horizontal bar is thin and low, which often causes dissatisfaction with filling. The reason is that in order to achieve a large negative tolerance, the pressure in the front of the finished product is too large, and the iron is too small, so the dissatisfaction with filling this hole occurs.

  4.假镀锌管的横截面是椭圆形,原因是厂家为了节省材料,成品辊前两个压力太大,这个管道的强度大大降低,也不满足钢管的标准尺寸。

  4. The cross-section of the fake galvanized pipe is elliptical, because in order to save materials, the pressure of the first two rollers of the finished product is too large, the strength of the pipe is greatly reduced, and it does not meet the standard size of the steel pipe.

  5.镀锌管的构成是偶数,冷切机的吨位高,切割头的端面光滑整洁,和下镀锌管由于不良材料,切割头的端面会经常有肉的现象,也就是说,不均匀,没有金属光泽。而由于劣质厂家产品割头少,头尾会出现大耳子。

  5. The composition of galvanized pipe is even, the tonnage of cold cutting machine is high, the end face of cutting head is smooth and tidy, and the end face of cutting head often has flesh phenomenon due to poor materials of lower galvanized pipe, that is to say, it is uneven and has no metallic luster. And because inferior manufacturer product cuts head little, head and tail can appear big ear.

  6.劣质镀锌管材质中含有杂质,钢密度小,尺寸超差,所以在没有游标卡尺的情况下,可以进行称重和校核。一般来说,更好是调整比例量,主要考虑累积误差和概率论的问题。

  6. The poor galvanized pipe material contains impurities, the steel density is small, and the size is out of tolerance, so it can be weighed and checked without vernier caliper. Generally speaking, it is better to adjust the proportion, mainly considering the problems of cumulative error and probability theory.
