摘　　要：介绍了Φ１０２ｍ ｍ Ｃ Ｐ Ｅ 机组采用定心与不定心管坯轧制， 其钢管成品壁厚的对比测量情况。实践证明， 采用定心管坯， 产品的壁厚精度得到明显的改善。The co authors introduce the comparison of measurements of wall thickness of the finished tubes made of centered blooms and non centered blooms with the Φ102mm CPE pipe mill.Relevant operational practice shows that the centered bloom can contribute to significant improvement of W.T.accuracy of the finished product.

关 键 词：CPE机组 管坯定心 钢管 壁厚精度
