How to calculate minimum bend radius?
(OP)
I have an issue with foam pigs being torn up in an 8" line. I have sourced a solid multiple cup poly pig to use as a temporary solution. It is an 8" pig, length = 16". It has a minimum bend radius of 12". I am concerned whether this pig will traverse a 45degree bend with internal diameter of 190.5mm. The manufacturer recommendation is a minimum ID of 194mm but I have told this is a very conservative number. The pig is fairly flexible but I just want to make sure it won't get stuck. Advice please?





RE: How to calculate minimum bend radius?
Put another way... Buy it and try it. If it gets stuck, increase the driving pressure by 2.075327% and see what happens. If the lost profit opportunity is so high that you are unwilling to take a chance on this, build a mock up and test the pig on that first.
