Issues regarding the welding of reinforcement rings
Thread Content
Appendix D of GB150.3 deals primarily with the structure of welded joints; D.3.1.2 covers nozzles equipped with reinforcement rings, and it states that such structures are not suitable for applications with steep temperature gradients. So the question arises: what kind of welding structure should be used for the reinforcement ring in situations with steep temperature gradients? Please give me some advice. Thank you all
The problem is indeed difficult to solve, as temperature differences cause stress
I mean, I don’t know how to solve this kind of problem
Reinforcing rings cannot be used in situations with sharp temperature gradients
Reinforcing rings cannot be used in situations with sharp temperature gradients
D.3.1.2 in Appendix D of GB150.3-2011. GB150-98J3.1.2
I took a look at Appendix D.3.1.2, which states that “these structures are not suitable for situations with steep temperature gradients.” It doesn’t state that reinforcement rings cannot be used in situations with a sharp temperature gradient. Is it possible to use a different welding structure with reinforcement rings?
I understand that reinforcement rings can’t be used. Using thick-walled tubes, etc
I’ll check all the applicable scenarios for reinforcing rings; in other words, the working conditions described by the poster don’t allow the use of reinforcing ring structures, and other types of reinforcement such as reinforced pipes or overall reinforcement should be employed instead.
The 10th floor ** is correct. The reinforcement ring structure cannot be used in situations with sharp temperature gradients.
