Will this work for broken stove pipe flange on top of a cast iron box stove it was dropped in shipping and broke out the top flange the pipe attaches?

No I think not , but if it’s just laying there in place and is cracked loose from the main flange .This would seal the crack but would add little support it’s to brittle.

Once i cut the tip end and start using it, how can i store it for later use? is that even possible? how different to other silicone caulking tubes?

Once opened, you can seal the tip with plastic wrap to help extend the life for up to a couple of weeks - this is not a product that is designed to be held on to for a while after opening, it will begin to cure as soon as it is exposed to air.

What is the minimum application temperature? 30F?

Yes, the application temperature is 30 degrees F up to 100 degrees F.

Can this be used to fill a crack in a Big Green Egg and if so would it stand up to the heat of the grill?

We do not recommend using this product to repair a crack in a Big Green Egg as this is designed for metal-to-metal or metal-to-masonry applications. You can use Rutland Products Castable Refractory Cement to make repairs to the cracks, once allowed to dry for 24 hours, this Castable Refractory Cement can be exposed to temperatures up to 2,200-degrees F.

Good stuff did what we wanted

My stone-tiles surrounding my gas fireplace were falling off and needed heat resistant cement for repair. Just used this and fixed my stone-faced fireplace. Should not have any problems with loosening stone-tiles from heat anymore. It's good to 2000 F.

Excelente para sellar las uniones de las placas de cerámica de un calefactor de gas, muy importante respetar los tiempos de secado y la primer cocción de 5 min
