Hydraulic Pipe Welding

by Steve


Can you tell me what welding certification is required for welding 3000 psi sch 80 hydraulic piping?

Thank you,



ASME section IX is often used for pressure piping and vessels.

But it depends on a lot of other things like what industry. There are codes for welding earthmoving equipment and we know heavy equipment has high pressure hydraulic lines.

AWS D14.3 is often used for heavy equipment but welding codes like this can reference other welding codes like ASME section IX for specific needs like hydraulic pressure lines.
