what grade of steel pipes gives 500 MPA (72ksi) yield strength?

[HanStrulo]

I have a weird question.

We usually use G40.21/21 pipe sections with Fy=310MPA in our design (canadian). The client asked for a Fy=500MPA pipes and I am not sure under which class or grade that falls? is it a special grade? is there a pipe grade that gives this yield strength?

Thank you

What do you need it for? For structural purposes it feels like you'd be able to just increase the wall thickness to deal with most problems.

That being said, you'll probably have better luck with 70ksi. I know there is at least
API 5L X70. I'm sure there are others. You're going to have to watch your welding processes I bet.

Well it's not a standard pipeline grade.

Closest is X70/ 485 MPa.

Very odd. Dies the client know what they are talking about?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

THanks for the comments.

The client does not want to increase the pipe thickness or diameter. I think they are for micro piles with alot of space restraints.
the procurement manager asked for the specs that will have a yield strength of 500MPA since it was the strength needed to make the section work.
