Seeking experience in ring-tube modeling for PDMS modeling

2016-09-07View Original

Thread Content

I’ve been working on modeling two catalytic cracking units recently. The pipelines are too complex, and using automatic connections or bends doesn’t yield satisfactory results. Are there any colleagues with experience in designing piping systems who can offer some suggestions?

If possible, first create a sample in CAD to determine the bending radius, and then proceed with fabricating the bent tube using PDMS. Alternatively, consider it as a square; the inscribed circle represents the bent pipe. Start from the center of the circle, create the bend for that circle, then move it to the desired position, and finally set the start and end points of the branch.

Mm-hmm, it’s indeed about calculating the radius and angle using lofting, but since the pipe fittings are straight,,,

What pipes are straight? Then it’s polygons.

The fastest method available at the moment is polygons

What kind of fitting? It’s straight, and it’s used on ring pipes too?
