How should the design temperature above the support be selected?
Thread Content
I’ve seen the new standard for supports, NBT47065, which includes a specified design temperature; these temperatures are all within the range of 200 to 300 degrees. But my equipment operates at a temperature of 500 degrees – how should I choose in such a case? For example: I use 15CrMoR material, which is capable of withstanding temperatures up to 500 degrees. Yet the specifications for the lugs state that this material can be used for applications with temperatures up to 300 degrees only. How can this contradiction be resolved?
Standard supports are not used; a custom design is adopted.
Can I use the same standard as that for the supports?
The dimensions can be used as a reference; calculations are done for non-standard cases
Refer to the standard writing as a guide, and then actually check the strength and such?
