Hello all,
which part of ASME is talking about longitudinal crack on a boiler tube. We got a 4-5 inches crack on down comers side and I need to follow ASME code to repair that. Your advice is highly appreciated.
Thanks

RE: Hello all, which part of ASME is
For in-service repairs of boilers you need to folow the National Board Inspection Code (NB-23 publication).
If this is a waterwall tube and yuo have an axial crack, I would replace the tube section with a dutchman (new tube) butt welded on each end to the existing tube away from the damage.
Use a qualified welding procedure based on material, and perform a post repair non-destructive test (x-ray) or other surface NDT.
