摘要
主要介绍了直径较大的螺栓实现预紧的一种新方法———螺栓加载拉伸技术。讨论了螺栓加载拉伸技术的原理，拉伸量计算方法，螺栓拉伸实现的步骤及校验的方法。这种技术对设备损伤小，密封组件受力均匀，从而使容器密封的可靠性大大提高。
This paper principally describes a new way to pretension studs of large diameters——stud loading tension technology,and discusses the rationale of the technology,the calculating method of tensioning amount,the step and the calibrating method to tension studs.The technology makes little damage on equipment,has seal assemblies uniformly forced and greatly increases the reliability of container seals.
