Leakage at the expansion joint at the outlet of the continuous reforming regeneration fan
Thread Content
Hello, dear friends: There is a leak at the outlet expansion joint of the regeneration fan K301 in our continuous reforming unit. The details are as follows: There are **seven small leakage points** on the second wave of this expansion joint; the largest of these leaks has a diameter of 10 mm, while the smallest ones are as tiny as a needle tip! The medium is chlorine-containing regenerated flue gas, with a temperature of 440°C and a pressure of 0.25 MPa; the material of the corrugations is Incoloy 800, supplied by Jiangsu Yaxing! The expansion joint has a guide cylinder! The entire expansion joint has three waves in total!
Not quite sure; the material should be fine
Insulation defects; local low temperatures may fall within the corrosion range. It is recommended to use an infrared thermometer to check whether the insulation meets the standards!
The material itself is fine; it’s likely that there are issues with the hydraulic equipment used in the manufacturing process by the manufacturer. Small holes with large pinholes can be detected during pressure testing before the products leave the factory – this is clearly a quality issue on the part of the manufacturer
The material is fine; is there a problem with the quality?
It seems not to be a problem with the theoretical material; it’s more likely to be a quality issue
