如何判断nd钢管好坏
作者:www.wxsgjc.com 时间:2019-04-02 09:44:30 浏览:0次
1、看nd钢管的表面。观察亮度和表面有无漏焊和脱皮等表面问题。好的nd钢管表面色泽光亮,一般情况下不会生锈。 1. Look at the surface of ND steel pipe. Observe the brightness and surface problems such as welding leakage and peeling. A good ND steel pipe has a bright surface and will not rust in general. 2、看材质。nd钢管化学成分是的基础。检查化学成分是否达标是nd钢管很重要的检查方式。还有就是检查是否精炼炉的材料。 2. Look at the material. The chemical composition of ND steel pipe is the basis. Checking whether the chemical composition is up to the standard is an important inspection method for ND steel pipes. The other is to check whether the material of the refining furnace is available. 3、看做工。圆管的圆度、方管的方度、表面的处理、nd钢管两端的处理、还有很重要的一点就是整只钢管的平直度。 3. Look at the workmanship. Roundness of circular pipe, squareness of square pipe, surface treatment, treatment of both ends of ND steel pipe, and a very important point is the flatness of the whole steel pipe. 4、好的nd钢管厂家拥有好的管理层、好的操作工、好的制度、有一定的知名度和信誉度,产出来的产品自然也能满足客户的高端要求。而一些小的或者不正规的钢管厂家生产出来nd钢管不仅在外观上与好的nd钢管有差距,其坚硬程度、韧性,也有很大的差距。 4. Good ND steel pipe manufacturers have good management, good operators, good system, a certain degree of popularity and credibility, and the products can naturally meet the high-end requirements of customers. And some small or irregular steel pipe manufacturers produced ND steel pipe not only in appearance and good ND steel pipe has a gap, its hardness, toughness, but also a big gap. |
