直埋蒸汽管道型式试验用沙箱试验机的开发

Development of Sand Box Tester for Type Test of Directly Buried Steam Pipeline

介绍了直埋蒸汽管道沙箱试验(总体抗压强度、工作管轴向移动性能试验)的内容及试验结果判定标准。探讨了自行研制的沙箱试验机的结构及工作原理,分析了设计制造、使用、维护中应注意的问题。

The content of sand box tests of directly buried steam pipeline （ including total compressive strength test and axial sliding performance test of service pipe） and the judgment criteria of test result are introduced. The structure and working principle of independently developed sand box tester are dis- cussed, and the problems to which attention should be paid in the design, manufacturing, use and main- tenance are analyzed.
