You will probably have to adjust your heat and speed to compensate for the thickness, plus your going to have ALOT of grinding to do!!

Is it Casing???

@ Tritium
I p/u this 4' x 5.5" x 5/16 wall pipe from a local metal yard this past week..... where they got it from.. who knows?

@ OxideOO

I figured there would be a lot of grinding... & I'm prepared for such.... My question however is, In pipe welding is there generally a higher quality steel used for whatever reason?

[Legacyartist247]

I notice a general softness when grinding on regular mild steel, & can recognize the difference between stainless easily. But this metal you really have to fight with. I imagine that's why the salesman put an emphasis on how it could only be cut with oxygen & acetylene.

[Oxide00]

For that I'm pretty sure there is a use for high quality steel depending on what is flowing through. Some may need the ability to resist chemical attack etc would be my guess.
I'm sure higher quality steel would have a place in nuclear power generation sector (though it would probably be stainless as carbon steel and high temperature fluids don't mix very well).

It looks like old oil field casing at that diameter.

Same guess that I had. Do you find those often in scrapyards in Texas??

[Legacyartist247]

I see them all the time, however this time I actually purchased some.

[Legacyartist247]

I guess I'll have to invest in an oxygen acetylene setup soon... That would help remove a lot more metal faster...

Two words: Plasma Cutter.

Get one. Fast and no gas bottles to deal with.

At my school we had oxy/prop bevelers, 5 for plate, and 4 for pipe. Unfortunately they rarley ever let us use the the pipe beveler saying that they might not have those out in the field. Instead they made us grind them (After beveling my first set of pipe with a grinder my hands felt like jello). Having an automatic beveler make things so much easier.

@ tritium

My pm256 has a plasma system.... However my compressor is acting up...

@ OxideOO

Could you tell if it was regular mild steel, or something different?

[Oxide00]

I'm sorry but I don't have an exact answer, however after some quick research it seems like the chemical composition of casings vary to suit its environment. Does anyone else want pitch in on this???

[martinnman]

You'll probably need to change the temperature and rate of thickness change, the more you have to be a lot of grinding to do.
