Basis for converter design

This post was last written by wang* nnan_126 on 2014-1-1 19:41 Edit: Our company's converter often leaks, and the frequency of leakage is higher than that of ordinary ones. In addition to frequent starts and stops, I have always thought that it is a defect in the design. Our company uses a converter with a cylinder diameter of three meters and two, made of Q345R, the inner diameter of the tube is 24mm, the wall thickness is 3mm, the material is No. 20 steel, the tubes are 5454, and there is no expansion joint. If you know, please tell me, or provide the basis for the relevant design and calculation process.
How high is the frequency? 1 unit per day or 1 unit per month? Converter leakage is mainly related to the following aspects:: 1. Poor quality control of converted hot water 2. The heat exchange effect of the equipment is poor and the steam in the equipment cannot be removed in time. 3. The dehydration effect of the system is poor and acid corrodes the equipment. 4. The equipment is of poor quality.
Generally, within 3 months of a new device, the converter will leak badly. . . . . I still think there is a manufacturing issue. . It will be fine after this period. . . Best of luck to you, brother!

If the temperature rises or cools down too fast, it is a forced aging test for the converter, so frequent leakage is normal. In addition, your converter does not have an expansion joint!
Can you explain in detail the impact of 1 and 2? The number of converter leaks is about once every 3-5 days (during production)
My thoughts are the same as yours, but I have no data to support it.
