Hello my name's Justin an I'm new to the group an new to all this I'm a welder an have been fascinated by forge welding an just recently bought a forge set up that just needs insulated I'm using a 10 in diameter pipe an was told to use kaowool with satinnite to finish insulating but was told satinnite can be brittle an if it gets a hole punch led in you need to redo the process I'm seeing welding temperature being around the 2300 degrees an i found this stuff called inswool thats moldable an is supposedly little more resilient to normal wear an won't have to worry about puncturing it an exposing the kaowool an release fibers in air that can harm you but the problem is it's maximum range is 2300 degrees so I'm wondering if anyone has used this how it holds up how often you need to change it ect. I contacted the company an they said I believe it will withstand the temperature but I'd like to get your guys feedback before I spent 80 bucks on a gallon of the stuff thanks in advance I apologize in advance if this is hard to read I'm typing fast 

Jmoon00, the question you're asking has been discussed at length in the Gas Forges section of the forum. Read over that info, and if you don't find the answer you need, ask again. 

Ok thanks since I'm new it's hard for me to navigate so I searched inswool moldable an it brought up one thing that didn't answer my question but thanks for giving me a more narrow place to looks appreciate the feedback

 

Knowing how to ask the right question is halfway down the path to knowledge. 

Jmoon,

I know nothing about gas forges but I did a search of the gas forges section.  I looked for topics about lining forges that had a lot of responses (more chatter = more information).  Try out this one and, if it doesn't tell you what you need to know check another!

Also check out Wayne Coe's sight (he's an IFI member who deals in forging equipment).  He can sell you the good versions of what you may need and provides plans you can work from.  http://www.waynecoeartistblacksmith.com/Forge_Supplies.html

Good luck and don't be afraid to spend a lot of hours reading until you really understand not just what to do but why you should do it.

Thanks for the info I really appreciate it

 

why not read a bit about gas forges, I will move this post  because it does not belong in tips and tricks

Let me know if I can help you.  You can call or send me an e mail.
