Ball material (Ball Valve) - Valve engineering - Eng-Tips
Mar 27, 2008 · JimCasey (Mechanical) 28 Mar 08 08:45. Also it depends what is running thru the valve. A105 is a little harder than 304 as peter stated, so something noncorrosive will see better service with the steel ball. ENP has a very low coefficient of friction in addition to the hardness Peter mentioned, so it reduces the valve's torque/actuator price ...
ASTM A105 vs ASTM A181/1 Flange - Eng-Tips
May 24, 2017 · A181 was replaced with A105 in the ASME Code. Historically, there was a A181-I, A181-II, A105-I and A105-II, with the difference being the tensile strength. Grade I had a minimum tensile of 60 ksi and Grade II had a minimum tensile of 70 ksi for both specifications. My 1968 version of B16.5 has both grades of A181 and both grades of A105, but ...

Jun 8, 2023 · The 2019 BPVC VIII Div 1 changed the classification of as-forged A105 flanges from Curve B UCS-66 to Curve A UCS-66 to address brittle fracture possibility. ASM A105 Pressure Temperature Rating - ASME B16.5 and ASME BPVC VIII Div 1 - Boiler and Pressure Vessel engineering - Eng-Tips
A-105 Flange MDMT - ASME (mechanical) Code Issues - Eng-Tips
A-105 Flange MDMT. The 2019 B&PV Sect VIII code changed the UCS-66 curve for as forged A-105 flanges from the b curve to the a curve which has the result of increasing the MDMT of those flanges from -20 to +18 deg F. I have a client with C3 refrigeration vessels with MDMT of -20 deg F that have as forged A-105 nozzles.
