    焊管与冷拔无缝钢管的制做过程的区别

    2018-11-29 14:01:44 无锡盛发地坪科技有限公司 阅读

    据我了解很多人对冷拔无缝钢管与普通冷拔钢管的区别不怎么清楚,今天我们就来说说他们的区别,其实仅仅从这两种管材的名字上就能够想到它们的主要不同之处。不过作为冷拔无缝钢管专业销售企业还是要给您略作介绍一下,让各位朋友对对冷拔无缝钢管与普通冷拔钢管的区别有一个大概的了解。

    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.

    冷拔无缝钢管与普通冷拔钢管主要是成型工艺不同。普通钢管,比如自来水水管,一般是通过将平板材经折弯后焊接起来的,你可以在上面发现一条焊缝;直径较粗的一般是螺旋焊缝。而无缝钢管一般是将熔融状态的钢水通过环形狭缝积压出来后再经拉伸等处理工艺成型,这样就没有焊缝,管材强度自然就高些,工业价值也会提升,价格也略高于普通冷拔钢管

    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 usually 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. 冷拔无缝钢管与普通冷拔钢管在性能上,尤其是承压能力上较普通钢管有很大提高,所以经常被用于高压设备上使用。如液压设备的管路连接等。而普通冷拔钢管的焊缝部位是其薄弱环节,焊缝质量也是影响其整体性能的主要因素。在北方生活过的人一般都有过自来水管或暖气管在冬天被冻爆的经历,爆的地方一般都是焊缝处。焊管不如无缝钢管结实。

    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.


    通过以上这两点区别比较,朋友们以后在购买管材的时候就可以轻易区分出什么是冷拔无缝钢管、什么是普通焊管了。虽然普通焊管较冷拔冷拔无缝钢管价格便宜不少,但其使用年限相当短,特别是在北方地区使用。普通焊管的使用寿命只有冷拔无缝钢管的一半,所以在长期工业用途中还是建议选购性价比高的冷拔无缝钢管。

    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.
