There are many reasons why, the tube plate sealing surface accuracy, installation problems, sealing problems, and so on, it is best to tear down, row by row

Leakage of pipe plate sealing surface can be investigated from four aspects:
1, the tube plate sealing surface is damaged?
2 、 does the tube plate have larger welding deformation?
3, gasket installation position is accurate?
4, whether the press process according to the process?
