old steel pipe
 
I have old steel pipe in my house it was build in the 50s dont have any trouble with it right now but its not insul and is it something i can do changing it out to pvc or should i just leave it alone i live in alabama

It will start failing eventually. My pipe is the same age and I have no issues. It really depends on your water quality.
A few people here will tell you to rip it out immediately :laughing:
Whatever you decide, don't use PVC as it is not approved for indoor use, nor is it allowed for HW use. I suggest PEX.
Do you have problems now?

Just for some clarification -
Are you talking "steel pipe" for your drains or your water supply lines?

once they go they go and my crystal ball is not working to let you know when:jester:

on a serious note if you are talking supply lines i would change them to pex easy to run and very cost effective as a person in the field i have a lot of good things to say about pex and one bad and that is it is to easy to install so i lose some work occasionally due to that and when you do switch the odds are it will increase your water pressure/volume

if you are talking about drain i would switch to pvc all at once is best option but at least each branch as it leaks or constantly clogs

Where do you live? If it doesn't get cold not as critical but typically water lines are on the inside of heating envelope of the house so they don't need to be insulated. Pex is likely more forgiving than your steel pipe when it comes to freezing I'd think so if the steel isn't insulated now, the pex likely would not need to be; your mileage may vary.

What is PVC for? Is it for potable water?

Yes, it's for potable water but most plumbing codes don't allow it inside a house. It's fine for distribution piping outside though
