Water-filled leak test procedure for stainless steel reaction pot

- Sep 29, 2018-

The stainless steel reaction pot is a device that realizes the heating, evaporation, cooling and low-speed mixing function required by the process by designing the structure and parameters of the container. It must be inspected before use. The stainless steel reaction pot is charged. Prior to the water test, all accessories and other components welded to the stainless steel reactor body shall be completed; all welds associated with the tightness test shall not be painted.


The water filling test of stainless steel reaction pot should adopt fresh water, the water temperature should not be lower than 5 degrees Celsius. For stainless steel reaction pot, the chloride ion content in water should not exceed 25mg/L. The aluminum floating roof test water should not corrode aluminum; the reinforcing ring should be Before the water filling test, 0.1-0.2 MPa of compressed air was introduced for weld leak detection.


In the water-filling test, the foundation settlement observation should be strengthened. In the water-filling test, if the foundation is not allowed to settle, the water should be stopped and the test can be continued after the treatment. During the filling and discharging process, the breathing valve port should be opened, and the foundation should not be immersed in water. The filling height is high operating level. When the strength of the stainless steel reactor is tested, the liquid level is maintained for 48 hours, and the stainless steel reaction vessel wall is observed to have no leakage.


When testing the strength and tightness of the top of the stainless steel reaction pot, the water level in the stainless steel reaction pot should be slowly filled with water at the liquid level. When the pressure is raised to the test pressure, the filling is observed without abnormal deformation, and the weld has no leakage. Qualified, the stability test of the stainless steel reaction pot top should be filled to the designed liquid level, and the water release method is used.
