摘　　要：分析了用计算式计算空拔管增减壁厚精度差的原因，指出了同管壁厚差、同架壁厚差、带芯棒拔制时管壁上浮是影响精度不可忽视的重要因素。The author analyzes the elements responsible for the deviation of the W.T.increase/decrease values of non-mandrel drawn pipe derived from relative formula,emphasizing that the major ele ments which can not be ignored are the W.T.deviation of the same length, the W.T.deviation of the same housing and the W.T.plus deviation occurring in the course of drawing with mandrel.

关 键 词：空拔管 壁厚精度 管材拉制
