摘　　要：在专门测试大壁厚、大口径无缝钢管耐压级别的特殊设备——THE-1200的静水压力试验机[1]上,为了满足被测钢管在规格范围内随机变化的要求,设计了一种宽幅端面密封[注:2]并成功加以应用。本文介绍了宽幅端面密封的设计和实践过程,指出了这种宽幅端面密封在使用中的优点和存在的问题,以及与其他密封方法的不同点。THE-1200 water testing machine called is successfully designed and applied for testing compression resistance grade of the pipes, especially high thickness and big diameter pipes. At the same time the machine can satisfy the requirement of the different diameter of the pipes in some range. The article introduces the design and test of the machine, and provides the strongpoint and problems in use. You can find the difference of seal solution between in our machine and in others.
