山东大鼎钢管厂After the steel pipe is sizing, enter the cooling tower and spray water to cool down. After cooling, the steel tube is straightened. After straightening, the steel pipe is sent to the metal flaw detector (or water pressure test) through the conveyor belt for internal inspection. If cracks occur inside the steel tube, bubbles will be found. After quality inspection, the steel pipe should be selected strictly by hand. After the quality inspection of steel pipe, paint quantity, specification, production batch number, etc.山东大鼎钢管厂精密无缝钢管均执行标准：GB3639-2000冷轧精密无缝钢管GB/T8162-2008结构用无缝管、GB/T8163-2008流体精密无缝管、GB/T3087-2008低中压锅炉精密管、GB/T5310-2008高压锅炉无缝管、GB/T17396-1999液压支柱精密钢管、GB/T6479-2000化肥专用合金管、GB/T3088-1982汽车半轴套管用无缝钢管、GB/T3093-2002柴油机用高压油管、GB/T8713-1988液压和气动缸筒用精密无缝钢管。浆纱机将锥形钻头冲入钢胚中，形成钢管。钢管的内径由钻头直径的长短决定。

精密钢管由于具有内外壁无氧化层、高压无泄漏、精度高、精度高等优点，主要用于生产气动或液压元件，如气缸或气缸等无缝或焊接产品。SH，没有冷弯变形，平整和无裂纹。精密钢管主要生产10、20、35、45、40cr、42CrMo级钢管等精密无缝钢管也可咨询供应。Through continuous improvement of service competitiveness, won the praise of the market. In addition, the company sells a variety of seamless steel pipe, alloy pipe welded pipe Chengdu Iron and Steel Group production, smelting iron and steel group, Baotou Iron and Steel Plant, Baosteel Group,and so on. Perhaps the fluid pipes used in previous transportation are seamless steel pipes. . However, with the continuous development of science and technology, technology and innovation research and development, welded pipe is now a very good development. Compared with seamless pipe, the thickness of the steel pipe wall is more uniform, and the accuracy is much better than that of seamless pipe. Now, in the United States or some developed countries in Europe, many seamless steel tubes are replaced by welded pipes.

添加钛、铌等微合金元素形成弥散的氮化物或碳氮化物，导致冷轧精密光亮钢管的韧脆转变温度升高。(3)晶粒尺寸对韧脆转变温度有影响，随着晶粒粗化，韧脆转变温度升高。冷轧和精密光亮钢管的晶粒脆化倾向得到了广泛的应用。高春铁（0.01% C）的Tc在该温度以下的100C完全易碎。冷轧精密光亮钢管中大部分合金元素都提高了韧脆转变温度和冷脆倾向。室温以上发生韧性断裂时，冷轧精密光亮钢管的断口为韧窝断裂，低温脆性断裂时断口为解理断裂。

Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast high production capacity application rate. Up to.0%, the rate of increase was normal.
