The Norwegian Posted July 2, 2019 Share Posted July 2, 2019 Does this pipe look galvanized or untreated steel? I put the tip in vinegar over the night, but it didn't seem to react a lot (Other than remove some of the rust and dirt? The second picture). I found it in my parent's basement and will use it for my first forge (JABOD). I know that sometimes they do rust some even if galvanized. The tip I left in vinegar over the night Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted July 2, 2019 Share Posted July 2, 2019 If you try using a standard picture format maybe we could tell, as it is your format is not readable Quote Link to comment Share on other sites More sharing options...
JHCC Posted July 2, 2019 Share Posted July 2, 2019 I can see the photos just fine, and it does look to me like it might be galvanized or have some other kind of plating. Not worth the gamble: use in a non-heated setting or sell it to the scrapyard. Quote Link to comment Share on other sites More sharing options...
The Norwegian Posted July 2, 2019 Author Share Posted July 2, 2019 Ok. Here is a video for good measure Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted July 2, 2019 Share Posted July 2, 2019 That is because he changed it to JPG now, rather than the format it was in Thank you, and it looks like it is galvanized Quote Link to comment Share on other sites More sharing options...
The Norwegian Posted July 2, 2019 Author Share Posted July 2, 2019 Good to know. I just thought that since the metal colour seems the same on the tip that had been in vinegar (other than dirt and rust), and since it didn't really react much to it, that it wasn't galvanised. But I have no experience at all so thank you for spotting this. Quote Link to comment Share on other sites More sharing options...

The Norwegian Posted July 3, 2019 Author Share Posted July 3, 2019 So I went to four hardware stores today. Only one had a pipe that was not marked galvanized. I asked the workers there, and they were no experts, since it was only marked "steel pipe" and did not say galvanized they said that it shouldn't be galvanized. It had some anti rust grease on the surface. But it was very shiny/glossy, and did not look like the rough more darker steel pipe I thought it would be, and I don't trust the workers there since they had no knowledge. From the looks, does it look like non-galvanized steel? Back side. You can see the seams Quote Link to comment Share on other sites More sharing options...
Buzzkill Posted July 3, 2019 Share Posted July 3, 2019 It does not appear to be galvanized to me. Ask for black iron pipe if you must buy new. Pretty much all stores that carry plumbing parts and pipes will have it in stock from about 3/8 inch up to 1.5 or 2 inch. Quote Link to comment Share on other sites More sharing options...

Here it is difficult to get such things. Will look in a specialised plumbing store next time. When I was making some accessories for my grill and needed some expanded metal, none of the many hardware stores in my city had it, many didn't even know what it was. Eventually I found this obscure industrial steel supplier for construction companies that had some left over that I could buy. Quote Link to comment Share on other sites More sharing options...
Buzzkill Posted July 3, 2019 Share Posted July 3, 2019 My apologies. I should have looked at your location before I posted. The pictures you posted last appear to be of uncoated steel pipe. However, if you put it in the forge and notice white or yellow powder-like material forming on the steel then remove it immediately and let the pipe cool down while staying out of the fumes/vapors.

Daswulf Posted July 3, 2019 Share Posted July 3, 2019 Degrease the end of the pipe and soak it in vinegar for a while. When you take it out it should rust within hours or a day if non-coated. Quote Link to comment Share on other sites More sharing options...
BillyBones Posted July 3, 2019 Share Posted July 3, 2019 I cannot speak for Norway, but here in the states black iron is used mostly for natural gas while galvanized is for plumbing water applications. Or at least used to be, mostly PVC i see anymore. So it may be worth looking into building codes to see what kind of pipe can be used for what applications. You could also look for automobile exhaust pipes. I have seen a lot of stainless but never a galvanized one. If it is going into a JABOD, maybe lay the pipe in and put clay around it, then when the clay is dry remove the pipe. Make a hollow passage rather than a steel pipe? I am assuming it will be side blast that is. I should clarify galvanized is used in high corrosion areas, not just plumbing. Things like fence post it is used. I just used the plumbing reference as to what part of my local hardware store i would go to if i needed a piece of pipe. Quote Link to comment Share on other sites More sharing options...
