3. Operating temperature of high alloy steel (stainless steel)
1. The lower limit of the operating temperature of ferritic stainless steel is 0℃. 2. The lower limit of the operating temperature of austenitic-ferritic stainless steel is -20℃. 3. The lower limit of the operating temperature of austenitic stainless steel is -253℃
Structural design should fully consider the factors:
1. The structure should be as simple as possible to reduce constraints.
2. Avoid excessive temperature gradient.
3. Sudden changes in the shape of the structure should be avoided as much as possible to reduce local stress.
4. The connecting part of the connecting pipe and the shell should be smooth, and the inner wall of the connecting pipe end should be rounded.
5. The support or leg of the container shall not be welded to the shell, and a backing plate shall be provided
