Hi everyone!
Are the UG-29(b) exemptions of un-supported stifferner rings applicable to Internal Stiffener rings, External Stiffner Rings or both?
Thanks
Hi All,
Just wondering if there is a difference between SA 516 Gr. 60 and 70 from equipment service point of view.
Other than material strength, is there any other deciding factor when chosing these two materials?
Thanks
