nd鋼管在日常工作中會存在一些安全隱患（huàn），我們一定要特別注意，稍不留神就可能釀成大患，給我們帶來不可估量（liàng）的經濟損失甚至危及生命安全。因此在使用nd鋼管時一定要注意檢查，排除隱患做好安全防範工作，那麽（me）nd鋼管有哪些重要的檢查方（fāng）法呢？首先要看管的表麵。觀察亮度和表麵有無漏焊和脫皮等表（biǎo）麵問題。好的nd鋼管表麵色澤光亮，一般情況下（xià）不會生鏽。
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. 第二點就是看材質。化學成分是nd鋼管的基礎。檢查化學（xué）成分（fèn）是否達標（biāo）是nd鋼管很重要的檢查方式（shì）。還有就是檢（jiǎn）查是否精煉爐的材料。
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.
第三點就是要看做工。圓管的圓度、方（fāng）管的方度、表麵的處理、nd鋼管兩端的處理（lǐ）、還有很重要的一點就是整隻（zhī）鋼管（guǎn）的平直度（dù）。
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.
最後，好的nd鋼管廠（chǎng）家擁有好的管理層（céng）、好的操作工、好的製度、有一定的知名度和信譽度，產出來的產品（pǐn）自然也能滿足客戶的高端要求。而一（yī）些小的（de）或者不正規的鋼管廠家生產出（chū）來nd鋼（gāng）管不僅在外觀上與（yǔ）好的nd鋼管有差距，其堅硬（yìng）程度、韌性，也（yě）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鋼管生產安全隱患錯綜複雜（zá），變化無（wú）常，難以預料和掌控，稍有大意，便（biàn）會釀成無法挽回的（de）經濟損失甚至危機生命（mìng）。隨著對工作熟練程（chéng）度的加深，有些職（zhí）工（gōng）逐（zhú）漸掉以輕心（xīn），自（zì）認為對操作流程熟（shú）練，從而忽略了基本的nd鋼管生產設備安全防範措施。一次漫不經心，一次不大的（de）失誤，會導致無法預料的後果，甚至是要付出血（xuè）的代價。
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（zhèng）所謂“安全第一，預防為主”。為nd鋼管生產線安全買份“保險”，這“保險”便是職（zhí）工的安全意識，隻有提高（gāo）職工的安（ān）全意識才能達到人人抓安全、人人重安全，才能（néng）將各類nd鋼管生產安全隱患消除在萌芽狀態。
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.
