"In order to seize the opportunity of the reform of state-owned enterprises, the reform of the public service sector can be tried first, relying on employees to realize the vision of development." In December 2014, the chairman of Xu Lejiang Company, Secretary of the Party Committee, put forward requirements and expectations for the branch of steel pipe and strip, and pointed out the direction of "winter training" for the branch. Steel pipe workers are moving. From 2015 onwards, the Ministry of Railways has been exploring and practicing on deepening reform by changing its concept and overcoming bottlenecks. In reform, 山东大鼎钢管厂、山东大鼎金属材料有限公司精密无缝钢管是采用冷拔或冷轧工艺生产的高精度、高亮度的无缝钢管。内外径可细化1～0.1mm，弯曲强度和扭转强度相同时，重量轻。精密无缝钢管用于精密机械结构、轴承液压、机械加工、液压设备、钢套管。广泛用于汽车、摩托车、电动汽车、石化、电力、船舶、航天、轴承、气动元件、中低压锅炉无缝钢管。

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。

Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司
