山东大鼎钢管厂The large stress and force at the upper yield point decrease firstly before yielding, and the lower yield point (_sl): the small stress at the yield stage is independent of the initial instantaneous stress. The yield point formula is: formula: FS yield strength (constant) in tensile test, N (Newton) SO original cross-section area, MM2. Fracture elongation (Sigma) In tensile tests, the percentage increase in the standard distance 山东大鼎金属材料有限公司between the specimens and the original standard distance is called elongation. The average daily capacity of copper in a year is expressed in sigma, with a unit of%. The formula is: Type: gauge length of L1 - after fracture, mm, L0 - original gauge length, mm. Section shrinkage山东大鼎钢管厂冷拔无缝钢管具有内外壁无氧化层、高压无泄漏、精度高、光洁度高、冷弯不变形、平整无裂纹、表面防锈处理等特点。主要用于汽车、摩托车的机械结构、液压设备和气动或液压元件。冷拔无缝钢管生产的工业控制包括模具设计、退火、酸洗、润滑等条件。同时，要搞好毛管质量检查和维修工作。

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.

山东大鼎金属材料有限公司Precision seamless steel pipe (cold-drawn and cold-rolled) has high precision, no oxidation coating inside and outside the pipe, smooth and smooth surface, uniform wall thickness, high precision, small diameter of thin-walled tube to ensure that the error of the outside diameter of the tube in the inner and outer surface of the pipe presents varying degrees and quantities of corrugated ring marks, some are continuous, some are intermittent, may be the entire circle, there are. Not the whole circle. poor quality of pickling and lubrication, increase and change of friction during drawing, mechanical properties of steel pipe in length direction after heat treatment are not consistent, mandrel length and fineness are too large, and the position of mandrel before.

山东大鼎钢管厂拥有台大中型冷拔机、两台辊底热处理炉、台大中型穿孔机和台热轧钢管机组三套先进的生产设备和成熟的生产工艺。公司拥有现代化的科研中心，拥有强大的性能测试、工艺性能测试、涡流测试、超声波测试、水力测试、金相测试、高精度碳硫分析等一整套测试方法，并拥有一批高素质的技术人员和检查员。硬度试验是根据规定的条件将硬质压头缓慢压入试样表面，然后测试压痕深度或尺寸，从而确定材料的硬度。
