山东大鼎金属材料有限公司Bearing steel pipe is a common rolling bearing ring made of hot rolled or cold drawn seamless steel pipe. The outer diameter of the steel pipe is 25-180 3.5-20mm, and it is divided into two Bearing steel is required to have high hardness and wear resistance, as well as high performance limit, because bearing bearings bear a lot of pressure and friction at work. The uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides in bearing steel are strictly required. It is one of the most stringent steel grades in all steel production.
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。
