采购精密管必看-欢迎选购

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。

3月份以来，国内无缝钢管的产量一直在放缓。中国2012年10月无缝钢管产量为248万#，比去年同期增长8.6%；1-10月无缝钢管累计产量达到22859万#，比去年同期增长6.9%。它也可以快速升级。中国无缝钢管产量在2018年11月为25.72亿，比去年同期增长299000，同比增长13.2%，同比增长3.71%，一月至十一月累计生产256.35亿。8.2%的蔗糖。公司主要生产产品：大口径厚壁直缝埋弧焊钢管、方管、矩形管、锥形管、非标钢管、复合钢管、无缝钢管、水电管、热膨胀钢管、热膨胀无缝钢管、拉杆。GE直径钢管、不锈钢管、低合金、合金钢管等，可根据用户要求制造。钢管材质为：Q23 5B、Q345 B、Q345 C、Q345 D、Q345 QD（桥梁专用钢管）、15CrMo、30CrMo、耐磨钢管、X46、X60、X70系列等非标特种钢管。
