Post-weld heat treatment equipment: what to do if the pre-welded parts fall?
Thread Content
The equipment for post-weld heat treatment has been installed on site. When installing the pipes, it was found that the pre-welded components of the pipe rack had fallen off. What should be done? The main material of the equipment is Q245R (normalized), with an operating pressure of 2.0 MPa and a temperature of 45°C. Seeking advice from experienced netizens, thank you!
After welding, perform local heat treatment
Can general equipment manufacturers handle this on-site?
Thank you to the two people above; I’ve never encountered such a problem and don’t know what to do
Austenitic welding electrodes can be used for welding, with no heat treatment required after welding
Weld the shims in place and heat them with a nozzle. Alternatively, doing nothing will have no effect.
Post-welding local heat treatment. If that really doesn’t work, send it back to the manufacturer for a complete heat treatment again...
It’s not important; if the client has low requirements, just bake it after welding； For important projects with high owner requirements, perform local heat treatment using electric heating.
The cost is too high, which puts a lot of pressure on us as the designers
Is it possible to modify the pipe rack structure without using a pre-welding plate...
