Copper Piping (Steam Rocket)

[cannon freak]

Does anyone know what kind of pressures 3/4" Type L Copper can take?

I'm making a small steam rocket, from some research Ive found that steam rockets are not all that wimpy, so I have basically all of the parts but the pipe, I have Type L copper but don't know what kind of pressure it can hold.

I can't tell you what it will hold, but will it cool to fast to be effective?

If it's drawn tubing (rigid), it's pressure rated to 875 psi.
...and I couldn't find the temperature derating factor.

Do you own domn homework.

I plan on heating the pipe externally and having a burst disc triggered by a pneumatic ramrod puncturing it.
