前就有用戶咨詢過無縫管的物理性能,但是有很多人對此還是迷迷糊糊的,不知道到底是什么,杭州亨鑫鋼鐵有限公司給我們介紹一下無縫管的物理性能。
 
  無縫管的特點:
 
  產品的壁厚越厚,它就越具有經濟性和實用性,壁厚越薄,它的加工成本就會大幅度的上升;其次、該產品的工藝決定它的局限性能,一般無縫鋼管精度低:壁厚不均勻、管內外表光亮度低、定尺成本高,且內外表還有麻點、黑點不易去除;其三、它的檢測及整形必須離線處理。因此它在高壓、高強度、機械結構用材方面體現了它的優越性。
 
  無縫管外觀質量
 
  無縫管內外表面不得有裂縫、折疊、龜裂、裂紋、軋折、離層和結疤缺陷存在,這些缺陷應完全清除掉(供機械加工用管除外),清除后不得使壁厚和外徑超過負偏差。凡不超過允許負偏差的其他輕微表面缺陷可不清除。
 
  D、直道允許深度。熱軋、熱擠壓鋼管、直徑小于和等于140mm的不大于公稱壁厚的5%,最大深度不大于0.5mm;冷拔(軋)鋼管不大于公稱壁厚的4%,最大深度不大于0.3mm。
 
  以上就是杭州亨鑫鋼鐵有限公司給我們介紹的無縫管的物理性能,經過以上杭州亨鑫鋼鐵有限公司的分享,相信很多人對此也有了一定的了解,希望可以幫助到你們。

Before the users consulted about the physical properties of seamless tubes, but there are many people are still confused about this, do not know what it is, Hangzhou Hengxin Steel Co., Ltd. to introduce us to the physical properties of seamless tubes.
The characteristics of seamless tubes:
The thicker the wall of the product, the more economical and practical it is, and the thinner the wall is, the higher the processing cost will be. Secondly, the technology of this product determines its limited performance. Generally, the accuracy of seamless steel pipes is low: the thickness of the wall is uneven, the brightness of the inner surface of the tube is low, the cost of the fixed ruler is high, and the internal surface is not easy to remove; Thirdly, its detection and shaping must be handled offline. Therefore, it embodies its superiority in high pressure, high strength, and mechanical structure materials.
Seamless tube appearance quality
The inner and outer surfaces of seamless tubes shall be free from cracks, folding, cracking, cracking, rolling, layering and scarring defects, which shall be completely removed(except for tubes used for machining) and shall not be removed so that wall thickness and outer diameter exceed negative deviation. Other minor surface defects that do not exceed the permissible negative deviation may not be removed.
D, straight channel allows depth. Hot rolling, hot extrusion steel pipes, not more than 5 % of the nominal wall thickness with a diameter of less than and equal to 140 mm, and a maximum depth of not more than 0.5 mm; Cold drawn(rolled) steel pipes are not greater than 4 % of the nominal wall thickness and the maximum depth is not more than 0.3 mm.
The above is the physical properties of seamless pipes introduced to us by Hangzhou henxin steel Co., Ltd.. After the above sharing of Hangzhou henxin steel Co., Ltd., I believe many people have a certain understanding of this, hope to help you.
