摘要
针对常见管螺纹连接在压力试验过程中的密封难题,设计2种新型的密封性、耐压性较好的压力试验工装。这2种工装具有安全、承受压力高、装拆快捷方便的特点,适用于各类压力容器、压力管道、换热器集水管等的耐压试验,且可以重复使用,制作成本低廉,具有较大的推广使用价值。
For sealing problem that common pipe with thread connection encounters during pressure test, designs two new types of pressure test fixtures with good sealing and resistance to pressure. The two fixtures have the features of safety, high pressure endur- ing, convenient assembly and disassembly, and are suitable for pressure test of various types of pressure vessels, pressure piping, catch-pipe of heat exchanger and so on, and can be re-used, low cost production, with great value of extension.
