looking for some existing fixturing or ideas on how to hold a very tight tolerance on butt welding a 4" fitting to 4" o.d. tubing with a perpendicular tolerance of .015"
we are tig welding and our current tolerance is .032" on this dimension, thank you in advance
Folks
for ASME-BPE Certification it is required for tack welds to be certified, similar to full GTAW welds.
the welders are to be certified Section IX as full welds are.
not an issue, however does any one know how to qualify the welds? you obviously cannot bend test
thank you
Forum Folks
see attached...i have a bracket w/1500 psi of pressure hitting the point shown
it is held in place with the static pin also as shown
we need this bracket to deform slightly yet not "bend" out of shape.
the bracket is .730" thick...everything is in inches
as of right now this thing...
hey folks

tubing is talked about, but is tubing covered under...

I have the following: 3.834 tube i.d., with 280 gpm (assuming water).
I need to know the psi running thru this system, nothing seems cut and dried, pressure drop is miniscule
things are off the charts in Crane's
any direction would be nice...
as always thank you
Guys
I have a sanitary ball valve where the Teflon seats are failing. product is propylene glycol running at 250 f and 100 psi
other products run at these temps and pressure with no issues
we are new to propylene glycol, but what I can find Teflon should be fine with this chemical
are there any...
Folks
I have been tasked to find the latest publication of multiple ASTM and ASME specs. for example:
ASTM not a problem easy to find ASTM A182 - 2016a...as the latest
what about ASME SA182? I know ASME will say ASTM A182 is fine for ASME SA182...however I cannot find what the most current...
Running into people asking for fittings with male/female perlick threads
can anyone point me to some detailed information on this thread??
i believe its a UNC type thread but can't say for sure
thank you
