nd钢管在使用前需要经过严格的检查，只有达到标准的产品才能使用，在检查nd钢管时会根据nd钢管的表面亮度，制作的材质及nd钢管产品的工艺手法来判断。现在小编要为大家介绍的就是nd钢管检查的三种方法。一次漫不经心，一次不大的失误，会导致无法预料的后果，甚至是要付出血的代价。正所谓安全第一，预防为主。为nd钢管生产线安全买份保险，这保险便是职工的安全意识，只有提高职工的安全意识才能达到人人抓安全、人人重安全，才能将各类nd钢管生产安全隐患消除在萌芽状态。
ND steel pipe needs to undergo rigorous inspection before use, only the products that meet the standard can be used. When inspecting ND steel pipe, it will be judged according to the surface brightness of ND steel pipe, the material made and the technological methods of ND steel pipe products. Now Xiaobian want to introduce three methods of ND steel pipe inspection. A carelessness, a minor mistake, will lead to unpredictable consequences, and even to pay the price of blood. The so-called safety first, prevention first. Buy an insurance for the safety of ND steel pipe production line. This insurance is the safety consciousness of workers. Only by improving the safety consciousness of workers can everyone grasp safety and put safety at the top of everyone's weight, and can all kinds of hidden dangers of ND steel pipe production be eliminated in the bud. 首先要看管的表面。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。
The first thing to look after is the surface. 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.
第二点就是看材质。化学成分是nd钢管的基础。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。
The second point is to look at the material. Chemical composition is the basis of ND steel pipe. 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.
第三点就是要看做工。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。
The third point is to 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.
最后，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。
Finally, a good ND steel pipe manufacturer has good management, good operators, good system, a certain degree of popularity and credibility, and the products produced 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.
在工作中nd钢管生产安全隐患错综复杂，变化无常，难以预料和掌控，稍有大意，便会酿成无法挽回的经济损失甚至危机生命。随着对工作熟练程度的加深，有些职工逐渐掉以轻心，自认为对操作流程熟练，从而忽略了基本的nd钢管生产设备安全防范措施。
In the work, the hidden dangers of ND steel pipe production safety are complex, changeable, unpredictable and difficult to control. A little carelessness will lead to irreparable economic losses and even crises of life. With the deepening of working proficiency, some workers gradually take it lightly and think they are skilled in the operation process, thus ignoring the basic safety precautions for ND steel pipe production equipment.
