沸腾炉换热管的试压工装

Equirpment of Pressure Testing of Heat Transfer Pipe of Boiling Boiler

在对沸腾炉换热管弯制完毕后进行试压时发现，按常规试压把弯制成形的换热管放在两台龙门虎钳上，用钳口压住管子外壁，管子一端堵住，另一端连接试压泵进行水压试验。结果发现由于管子空间成形角度不同，难以装夹。另外管子外壁压得太紧，管口成椭圆，管子外壁容易出现压...

Abstract In the paper,a new equirpment of internal-expanded type pressure testing for solving previous problems in pressure testing is introduced.
