Heat transfer though anchor bolt

Heat transfer though anchor bolt

Heat transfer though anchor bolt

(OP)
We have a slurry tank heated to 135F. The slab is 36 in. and the 2 in. diameter anchor bolt is embedded 24 in. into the slab. Underneath the slab is a pump room we are assuming is kept at 80F. We need to know at what point the anchor bolt temperature drops to 120F to start using epoxy.

Is there a simplified method to do this calculation without having to do a finite element analysis?

RE: Heat transfer though anchor bolt

I'm not sure you are going the find an answer with the degree of certainty that would make the adhesive 100% reliable. Or maybe you can find an adhesive which is still good well above 135.

Is there an opportunity to use a bolt with a mechanical type of anchorage? If in-place field adjustment is what you are looking for, I've had some luck with DECO adjustable anchors. www.decomfg.com

Unfortunately it is a retrofit and we are coring out the existing anchor bolts and replacing them with high strength bolts

RE: Heat transfer though anchor bolt

There is likely not enough heat transfer from the tank to the bolt to get it to 120 deg.
