摘　　要：为了防止套管早期断裂及螺纹不耐磨,通过分析套管服役条件,从结构设计,材料选择及加工工艺上,提出改进措施,达到套管耐磨损和抗冲击性能得以提高的目的。to prevent the pre-mature brakeage of the easing pipe and improve tire poor wear-resistance of its threads, the paper analyzed the usage conditions of the easing pipe and proposed some improvements in terms of the structural design, material selection and machining process. As a result, the wear-resistance and impact-resistance of tire casing pipe are enhanced.
