tube bend design criteria
tube bend design criteria
(OP)
i have several questons...
1) what is the standard for a tube bend radius?...is it three times the tube OD?
2) if you were to deviate from a standard bend radius, does it affect the tube wall thickness and how?...will there be an affect on pressure or temperature if it is a fuel line for a liquid propellant?
3) besides routing concerns, what should i be aware of for a good tube design?

RE: tube bend design criteria
D stands for the nominal size in inches (not the outside diameter).
Example 10" pipe, then bend radius 1.5*10=15"
3) The larger the bend radius, the more flexibilty is put into the system. This is important when you design systems for high temperature en large diameters (<4").
