焊管與冷拔無縫鋼管的制做過程的區別

據我瞭解很多人對冷拔無縫鋼管與普通冷拔鋼管的區別不怎麼清楚，今天我們就來說說他們的區別，其實僅僅從這兩種管材的名字上就能夠想到它們的主要不同之處。不過作為冷拔無縫鋼管專業銷售企業還是要給您略作介紹一下，讓各位朋友對對冷拔無縫鋼管與普通冷拔鋼管的區別有一個大概的瞭解。
As far as I know, many people don't know the difference between cold-drawn seamless steel pipe and ordinary welded pipe very clearly. Today we will talk about the difference between them. In fact, we can only think of the main differences between the two pipes from their names. However, as a professional sales enterprise of cold-drawn seamless steel pipe, I would like to give you a brief introduction, so that friends have a general understanding of the difference between cold-drawn seamless steel pipe and ordinary welded pipe.
冷拔無縫鋼管與普通冷拔鋼管主要是成型工藝不同。普通鋼管，比如自來水水管，一般是通過將平板材經折彎後焊接起來的，你可以在上面發現一條焊縫；直徑較粗的一般是螺旋焊縫。而無縫鋼管一般是將熔融狀態的鋼水通過环形狹縫積壓出來後再經拉伸等處理工藝成型，這樣就沒有焊縫，管材強度自然就高些，工業價值也會提升，價格也略高於普通冷拔鋼管。
Cold-drawn seamless steel pipe is different from common welded pipe mainly in forming process. Ordinary steel pipes, such as tap water pipes, are usually welded by bending the plate. You can find a weld on it; the larger diameter is usually spiral weld. Seamless steel pipes are us环氧地坪ually formed by backing up molten steel through annular slits and then stretching, so that there is no weld, the strength of pipes is naturally higher, the industrial value will be increased, and the price is slightly higher than that of ordinary welded pipes.冷拔無縫鋼管與普通冷拔鋼管在性能上，尤其是承壓能力上較普通鋼管有很大提高，所以經常被用於高壓設備上使用。如液壓設備的管路連接等。而普通冷拔鋼管的焊縫部位是其薄弱环節，焊縫質量也是影響其整體性能的主要因素。在北方生活過透水地坪的人一般都有過自來水管或暖氣管在冬天被凍爆的經歷，爆的地方一般都是焊縫處。焊管不如無縫鋼管結實。
Cold-drawn seamless steel pipe and ordinary welded pipe have a great improvement in performance, especially in bearing capacity, compared with ordinary steel pipe, so they are often used in high-pressure equipment. Such as pipeline connection of hydraulic equipment. The weld position of common steel pipe is its weak link, and the quality of weld is also the main factor affecting its overall performance. People who have lived in the North usually have the experience of water pipes or heating pipes being frozen and exploded in winter. The places where the pipes exploded are usually welded seams. Welded pipe is not as strong as seamless pipe.

通過以上這兩點區別比較，朋友們以後在購買管材的時候就可以輕易區分出什麼是冷拔無縫鋼管、什麼是普通焊管瞭。雖然普通焊管較冷拔冷拔無縫鋼管價格便宜不少，但其使用年限相當短，特別是在北方地區使用。普通焊管的使用壽命隻有冷拔無縫鋼管的一半，所以在長期工業用途中還是建議選購性價比高的冷拔無縫鋼管。
By comparing the above two differences, friends can easily distinguish what is cold-drawn seamless steel pipe and what is ordinary welded pipe when they buy Pipes in the future. Although common welded pipe is much cheaper than cold drawn seamless steel pipe, its service life is quite short, especially in northern areas. The service life of ordinary welded pipe is only half of that of cold-drawn seamless steel pipe. Therefore, it is recommended to choose cold-drawn seamless steel pipe with high cost performance for long-term industrial use.
