nd鋼管在使用前需要經過嚴格的（de）檢查，隻有達到（dào）標準的（de）產（chǎn）品才能使用，在檢查nd鋼（gāng）管時會根據nd鋼管的表（biǎo）麵亮度（dù），製作的材質及nd鋼管產品（pǐn）的工藝手法來判斷。現（xiàn）在小編要為大家介紹的就是nd鋼管檢查的三種方法。一次漫不經心，一次不大的失誤，會導致（zhì）無法預料的後果，甚至是要付（fù）出（chū）血的代（dài）價。正所謂安全第一，預防為主。為（wéi）nd鋼管生產線安全（quán）買份保險，這保險便是職工的（de）安（ān）全意識，隻有提高職工（gōng）的安全意識才能達到人人抓安全、人（rén）人重安全，才能將各（gè）類nd鋼管生產安全隱患消除在萌芽狀態。
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. 首先要看管的表麵。觀察亮度和表麵有（yǒu）無（wú）漏焊和脫皮等表麵問題。好的nd鋼管表麵色澤光亮，一般情況下不會生鏽。
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（gāng）管的基礎。檢查化學成分是否達標是nd鋼管很重要的檢查方式。還有就是檢查是否精（jīng）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、方管的方（fāng）度、表麵的處理、nd鋼管兩端的處理（lǐ）、還有很重要的（de）一點就是整隻鋼管的（de）平直（zhí）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.
最後，好的nd鋼管廠家擁（yōng）有好的管（guǎn）理層、好的操作工、好的製度、有一定的知名（míng）度和信譽度（dù），產出來的（de）產品自然也能滿足客戶的高端要求。而一些小的或者不正規的鋼管廠家生產出來nd鋼管不僅在外觀上與好的（de）nd鋼管有差距，其堅（jiān）硬程度、韌性，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鋼管（guǎn）生產安全隱患錯（cuò）綜複雜，變化無（wú）常，難以預料和掌控，稍有大意，便（biàn）會釀成無法挽回的經濟損（sǔn）失甚至危機生命。隨著對工作熟練程（chéng）度的（de）加深（shēn），有些職工逐（zhú）漸（jiàn）掉以輕心，自認為對操作流程熟練，從而忽略了基本的nd鋼管生（shēng）產設備安全防範（fàn）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.
