35499Re: [MILL_DRILL] Acetal pressure rating
- Feb 26, 2014You could always build one and perform a hydrostatic test on it of 150% or so. Of course having a set of calibrated dead weights makes this an easier chore, then you would be able to know by the pound what pressure you are really testing to.
But from the sound of everything, you probably have a large safety factor already in your planned design!

That would be with NO safety factor.The various places I worked, we generally used a Safety Factor of 4, when calculating hydraulic tubing.So….more like 1188 PSI. Still plenty of overkill….but knowing always give a guy a warm fuzzy feeling……JHmmm, 1/2" OD, 0.125" wall, breaking pressure of 4750psi. Seems a "little" high. I think I'll be ok with any wall at 50psi!On 02/26/2014 10:24 AM, Bill wrote:Leave any cell blank, and it’ll calc it for you.For some safety factor, multiply the OD by the safety factor, and enter that number as the OD, rather than the actual OD.Bill
