Can somebody advice me about the use of A234 WPB fittings in the
place of A420 Gr.WPL6 for the LPG line.
I hope,A234 WPB is for medium and elevated temperatures,whereas A420
is for lower operating temperatures. and moreover A420 is having
impact test properties.
So i hope we cant use the A234 WPB in place of A420,even though
tensile properties are same.
In my project,Design Temperature of LPG line is -45 deg to +85 deg.
Is my statement is correct?
Regards,
Thiru.
