nd钢管在日常工作中会存在一些安全隐患，我们一定要特别注意，稍不留神就可能酿成大患，给我们带来不可估量的经济损失甚至危及生命安全。因此在使用nd钢管时一定要注意检查，排除隐患做好安全防范工作，那么nd钢管有哪些重要的检查方法呢？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。
There are some hidden safety hazards in the daily work of ND steel pipe. We must pay special attention to it. A little carelessness may lead to serious hazards, which will bring us immeasurable economic losses and even endanger life safety. Therefore, when using ND steel pipe, we must pay attention to inspection, eliminate hidden dangers and do a good job of safety precautions. What are the important inspection methods for ND steel pipe? 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 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。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。
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. A careless, a minor mistake, will lead to unpredictable consequences, and even pay the price of blood.
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。
The so-called "safety first, prevention first". Buy a "insurance" for the safety of ND steel pipe production line. This "insurance" is the safety awareness of workers. Only by improving the safety awareness of workers can everyone grasp safety and attach importance to safety, and can all kinds of hidden dangers of ND steel pipe production be eliminated in the embryonic state.
