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。

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
