The length, diameter and using time of mandril are needed in the process of manufacturing the pipe.
在扩管生产中，需要实时了解每根顶杆的长度、外径、使用次数等信息。
Top effort, mandril should have sufficient strength, should head out of uniform, mandrel not served as core.
顶出力大，顶杆应有足够强度，顶出应均匀，顶杆不宜兼作型芯。
The maximum stress occurs on the surface of the mandril and small stress occurs on the other part of the mandril.
芯模的最大应力出现在芯模的浅表层，在周向表面上呈点状分布，而芯模其他部位承受的应力并不是很大。
