The ISO diagram shows a northward orientation that does not match the layout plan – would you dare to use it?
Thread Content
I encountered a strange homeowner: the axis of the structure forms a 15-degree angle with PN on the north side of the platform, while the piping is arranged parallel to the structural axis. However, in the ISO diagram, the pipeline layout does not have this 15-degree angle; the reason given is to facilitate reading of the diagram and construction. :L
I don’t dare to use it. . It seems like the PN code on the ISO diagram is incorrect. . . Or there is simply no PN at all. . .
An N is marked in the upper left corner of the ISO diagram, and the layout diagram shows the angle between PN, N, and the wind direction.
This one. . . Are you sure it’s not a problem with the design institute but rather a problem with the wild boars? Aren’t many ISOs created using software? Could they really be drawn by hand?
I’ll give you a piece of English text; figure it out on your own. We believed it was not convenient to subcontract the spool fabrication work, so the PDMS draft attribute was adjusted to be displayed with a vertical angle.
Did the wild boar say that? Is it inconvenient to construct with axonometric drawings?
The detailed design manager said that they find it inconvenient to view the drawings.
I’d like to ask to what extent spool fabrication has been carried out. . . Our understanding is that certain pipe fittings are pre-welded together, with a section left as an adjustment section to be welded on-site. . I’m not sure how your company views SPOOL. . .
All flange connections, as well as butt welds, plug welds, and threaded joints that are not suitable for lifting. . .
Our clients are quite peculiar; for SPOOL, they only accept butt welding of pipes and reject any other welding methods. . For example, butt welding of elbows and pipes is not accepted; there must be straight sections at both ends of the elbow to ensure that butt welding of the pipes takes place. . .
He is worried that the quality of the pipe fittings might not be up to standard during welding, resulting in additional rework, right?
