高压合金管的主要生产流程:管坯及坯加热、管坯的穿孔、钢管的延伸。
The main production process of high-pressure alloy pipe: billet and billet heating, billet perforation, steel tube extension.
高压合金管的轧制、钢管定径与减径、钢管的冷却和精整 或者可以说是 钢胚的加热 穿孔 热扎 酸洗 冷拔 碳烧 切头 喷标 包装 成品一种无缝钢管的制造方法,其特征在于:设置将具有多个轧辊的轧制机座、以互相不同的轧制方向连续配置多台的芯棒式无缝管轧机,在这样的制造生产线上对无缝钢管进行轧制后,在多点上测定轧制后的钢管圆周方向上的壁厚,根据其测定结果,至少分别控制芯棒式无缝管轧机的最终轧制机座上的轧辊各个轴的两端位置,以便使壁厚不均达到最小。一般合金管>合金管>合金管>高压合金管简称无缝钢管,用普通碳素钢、优质碳素钢、普通低合金钢和合金结构钢制造,用于制作输送液体管道或制作结构、零件用。高压管按外径和壁厚度供货,在同一外径下有多种壁厚,高压管承受的压力范围较大。通常钢管长度,热轧管为3-12.5m,冷拔(轧)管为1.5-9m。
Rolling of high-pressure alloy pipe, sizing and reducing of steel pipe, cooling and finishing of steel pipe, or can be said to be the finished product of hot piercing, hot pickling, cold drawing, carbon burning and cutting head spraying packaging of steel embryo. A manufacturing method of seamless steel pipe is characterized by setting up a rolling stand with multiple rolls and a mandrel seamless tube rolling mill with zhongyaocai.71ix.combaohuqi.07858.netzaoxingzd.37ix.com.cnlangfang.71ix.cndifferent rolling directions. After rolling the seamless steel tube on such a production line, the wall thickness of the zhongyaodou.71ix.comkakou.37ix.com.cnrolled steel tube in the circumferential direction is measured at many points. According to the measured results, the positions of the ends of the rolls on the final rolling stand of the mandrel seamless tube mill are controlled at least separately so as to minimize the uneven wall thickness. Seamless steel pipes are made of common carbon steel, high quality carbon steel, common low alloy steel and alloy structural steel. They are used to make pipelines for conveying liquids or structures and parts. High-pressure pipe is supplied according to its outer diameter and wall thickness. There are many kinds of wall thickness under the same outer diameter. The pressure range of high-pressure pipe is large. Usually the length of steel pipe is 3-12.5 m for hot-rolled pipe and 1.5-9 m for cold-drawn (rolled) pipe.
