X65 pipe
X65 pipe
(OP)
Starting a new weld test on X65 pipe, but don't have API 5L specification. What is the elongation requirement? Is the elongation of X65 20% or greater so that 3/8" thick bends are required?
Thanks
Thanks

That's what I need to know!

Chem is as follows: .067C, .239Si, 1.59Mn, .044Nb, .001V, .028Al, .015Cu, .018Ni, .184Cr, .002Mo, .022Ti, 66ppm N, .019P, and .003S.
Current mech properties are: 630 MPA tensile, 515 MPA yield, 38% elongation.

Sounds like the obvious, but do you have enough X-65 pipe material to run a coupon with and without PWHT? That would be your best bet. Hot rolled condition does not necessarily imply a normalized condition, other than the pipe was hot worked at some temperature above the lower critical transformation temperature and cooled in air. It might well be that PWHT may have minimal effect on the X-65 tensile properties.
