Pipe section processing drawing
Thread Content
Party A has requested us to process pipe sections from forged billets; they provided a drawing, but no specific dimensions were given for the bulged area in the middle of the pipe section – only a few symbols were indicated. Due to limited capabilities, we are unable to understand what those symbols mean. Could someone please help by providing a clear explanation? Thank you! Appendix: Areas marked in red in the diagram.
It is not welded to the flange neck. . .
This is a welding symbol; it has nothing to do with the dimensions of the boss. Ask the client for the relevant data – there’s no information available regarding the outer diameter or height of the boss

Thank you; I think it’s also aimed at welds
Welding symbol, external groove – this is confirmed. It’s just that codes 3 and 8 seem rather strange; I’ve checked all the welding codes I’ve seen and none like these exist. I mean, with such high pressure in this pipe section and an RJ seal surface, designing such a protrusion – I find it quite challenging to figure out how to manufacture it
Yes, it’s a challenge when it comes to processing. Thank you for the help!
3 indicates gas welding; a single V denotes a single-sided groove, with a groove width of 8 mm, and the groove is located on the side of the branch pipe
Weld symbol. It indicates a single-sided V-shaped weld with the weld seam on the side of the arrow, protruding; the bevel angle is 8° (although this value should be around 30° and should be confirmed with the other party), with 3 welds of the same type. For details: GB/T 324-2008 \"Code for Representation of Weld Symbols\"
:Lol, the weld symbol doesn’t match what the weld actually looks like. . You write yours, he draws his. . . Meaning of the symbols: It indicates that the weld is on the side of the arrow; it is a single-sided V-shaped weld. There are 3 such welds in total. 8: My guess is that the groove depth is 8 mm. Or the effective weld thickness is 8 mm. . rather than a groove angle of 8°
The fitting should be a standard component – a welded branch pipe fitting, and its dimensions need not be specified
