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。


山东大鼎钢管厂There are several special bearing steel grades in the production of bearing steel pipes (G for "rolls"): chromium bearing steel such as chromium-free bearing steel such as G20CrMo carburized bearing steel G20Cr2Mn2Mo9Cr18 and other high carbon chromium stainless steel bearings.

The ability of metal materials to resist indentation of hard objects has a small circumference/area ratio on all geometric sections, i.e., large internal sections can be obtained with the same number of materials. Because of its low cost and high strength, steel pipe has been widely used in modern fluid transportation. According to the different production process, the steel pipe is divided into seamless steel pipe and welded steel pipe, they are divided into high frequency longitudinal welded pipe (ERW), spiral welded pipe (SSAW), submerged arc welded pipe (UOE) and so on. In the past, traditional seamless pipes were used for fluid pipelines.山东大鼎钢管厂
精密钢管是冷拔或热轧后的一种高精度钢管材料。精密钢管主要用于生产气动或液压元件,如气缸或气缸的产品,它们可以是无缝的或焊接的,但大多数是精密无缝钢。管。精密钢管具有尺寸精度高、表面光洁度高、热处理后管内外表面无氧化膜、管材无压扁裂纹、冷弯变形、耐高压、能进行各种复杂变形和机械加工等优点。深加工。主要生产钢管牌号:10, 20, 35、45、40Cr、42CRMO等。精密钢管;GB/T699—2008;GB/T3639-2008。


山东大鼎金属材料有限公司Welded steel pipe is welded by butt weld or spiral weld. In the manufacturing method, it can be divided into low-pressure fluid conveying welded steel pipe, spiral welded steel pipe, direct rolling welded steel pipe, electric welded pipe and other precision steel pipe itself, metal deformation is more uniform, which makes precision steel pipe, part of which, in the process of hardening. For example, when the deformation part is hardened, the deformation will not spread to other non deformed parts. This ensures that the deformation of the pipeline during use will not cause damage or loss.山东大鼎钢管厂27siMn精密钢管的力学性能;抗拉强度屈服强度伸长率截面收缩率冲击吸收能冲击值力学性能试验方法;所有精密钢管都应满足要求。测试机械性能。测试力学性能的方法主要有两种,一种是拉伸试验,另一种是硬度试验。拉伸试验是将精密钢管制成试样,然后在拉伸试验机上拉断试样,然后测量一个或多个力学性能,通常只测量拉伸强度、屈服强度、断裂后伸长率和截面收缩率无缝钢管由优质碳素钢或合金钢制成,分为热轧和冷轧(拉拔)。
