The products can be rough castings or cold parts. The company has six production lines of large and medium-sized cold-drawn precision seamless steel pipe and cold-rolled precision seamless steel pipe mill, one roller hearth heat treatment furnace and three sets of ordinary cold-drawn seamless steel pipe mills. Advanced production testing equipment is a necessary guarantee for high quality precision seamless steel pipe, so the company is very modern production equipment, to ensure the level of the industry. The seamless cold rolling equipment adopting foreign advanced technology has the characteristics of high precision, wide production specifications and models, flexible and so on. It is more advanced than the ordinary automatic cold rolling mill, and equipped with advanced automatic control and on-line detection. Ensure product reliability and reliability

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。精密钢管由于具有内外壁无氧化层、高压无泄漏、精度高、精度高等优点，主要用于生产气动或液压元件，如气缸或气缸等无缝或焊接产品没有冷弯变形，平整和无裂纹。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、管材平整无裂纹、冷弯变形、耐高压等特点，可用于各种复杂的变形和机械加工。深加工不同之处在于：无缝钢管的主要特点是无焊接接头，能承受较大的压力。

"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。
