山东大鼎金属材料有限公司Precision steel pipe refers to high precision steel pipe whose wall thickness and inside and outside diameter can be controlled within the tolerance range of the steel wire. This kind of steel pipe is different from the outside surface of common hot-rolled seamless steel pipe and cold-drawn seamless steel pipe. Hot-rolled, precision steel tube surface and inner diameter smooth, color and stainless steel, the internal and external surface due to manufacturing reasons are with a layer of oil size precision, good surface quality seamless steel tube is called precision steel tube. Precision tube is a high density and high brightness seamless steel tube produced by cold drawing or cold rolling process. 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。精密钢管是近年来出现的一种产品。这主要是由于内孔和外壁的严格公差和粗糙度。
Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.
