挤压垫片是一种在挤压筒内将挤压杆与锭坯隔开并传递挤压力用的挤压工具。
这可以对开展扁挤压筒挤压技术的研究及扁挤压筒用固定挤压垫片的设计与实际应用提供参考。
This will provide references for the design and practical use of the fixed dummy blocks for flat container.
而且，从根本上来说，ANSI法兰是壹种无效的密封，它需要把50%的螺栓负荷用于挤压垫片，而用于保持压力的负荷只剩50%。
And, essentially, is one kind of invalid ANSI flange sealed, it needs to put 50% of the bolt load for dummy blocks, and to be used for pressure load of only 50%.
ANSI法兰的密封原理极其简单：螺栓的两个密封面相互挤压法兰垫片并形成密封。
ANSI flange sealing principle is very simple: bolt two seal face mutual extruding flange gaskets and formed the seal.
