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）。
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。
Some distributors seize this point and work with downstream end users to inform seamless steel mills of their respective requirements for precision steel pipes and then send the products directly to end users for use. This method is helpful for dealers to firmly grasp the needs of the downstream end-users. It can not only transport precision steel pipes from the precision steel pipe mill to the downstream end-users, but also ensure that the end-users can use seamless steel pipe products more quickly. In this way, the efficiency of the precision steel pipe is improved,of pure trade has become increasingly limited, to expand the precision steel pipe processing business, so that they can not be replaced in order to survive.液压和气动缸筒用精密内径无缝钢管（GB8713-88）是制造液压和气动缸筒用的具有精密内径尺寸的冷拔或冷轧精密无缝钢管。供暖采用聚氨酯保温管那是一种趋势 直埋式外压波纹补偿外壳及导向套筒保护下实现自由伸缩补偿冷拔或冷轧精密无缝钢管（GB3639-83）是用于机械结构、液压设备的尺寸精度高和表面光洁度好的冷拔或冷轧精密无缝钢管。选用精密无缝钢管制造机械结构或液压设备等，可以大大节约机械加工工时，提高材料利用率，同时有利于提高产品质量。精密钢管的种类很多。许多精密钢管需要在下游用户使用之前进行加工。
