Semi-tube welded joint
Thread Content
Looking at the previous drawings, the half-pipe joint had an internal groove – should an external groove be used instead?
I don’t understand why an internal groove is used...
The drawing is incorrect; it must be an external groove
Which standard includes this half-tube welding structure?
This should be common sense; standards do not provide detailed regulations on it.
Hmm, I feel this structure is quite special. I thought it would be available on 20583, but it wasn’t, which is why I asked. I guess I’ll have to modify it myself then, haha
A better structure, usable both inside and outside; the inner slope is better!
How to weld an internal crack in a DN50 half-pipe?
As a supplementary note, I’m welding five and a half turns of pipe on a DN1600 container; it’s not possible to weld at the inner groove, right?
This is a pipe cap; where is the half-pipe welding joint? Check GB/T12459-2005 for it
Or it could be a spherical head; from the diagram, it doesn’t appear to be a pipe cap, so it should be a hemispherical head
