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。
Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管（GB/T8162-2008）是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管（GB/T8163-2008）是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度，尺寸精度高，越来越受到客户的青睐。
Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
山东大鼎钢管厂公式计算钢管的理论重量：W=(D-S)＊S＊0.02466，其中W=钢管每米的重量；S=钢管的公称壁厚；D=钢管的公称外径，光亮管的表面质量i清洁、无氧化层、无裂纹、折叠、轧制、结疤、分离层和条纹。
