为了配合西气东输管道工程内涂层质量监测的需要,根据 API 5L2的技术要求,设计研制了内涂层起泡试验设备。 内涂层起泡试验要在设定压力下维持 24h,该装置在压力回路上安装了4个压力容器,一次性可以完成多个试件实验,从而能有效地提高工作效率。同时,也可以根据测试需要,在其中的一个或几个容器中做水压试验,在另外的容器
In order to meet the need of inner coating quality monitoring of West-East Gas Pipeline Project, according to the technical requirements of API 5L2, the inner coating foaming test equipment was designed and developed. The inner coating blistering test is to be maintained at a set pressure for 24h, and the device is equipped with 4 pressure vessels on the pressure circuit, so that multiple test pieces can be completed at one time, thereby effectively improving work efficiency. At the same time, according to the test needs, in one or several of the container hydrostatic test, in another container
