I am trying to establish pressure temperature chart for P92 / F92 material. This material has been in use for more than a decate but not listed under ASME Section II Part D, ASME B31.1 or ASME B31.3.
Please let me know if there is any publication for P92/F92 material which lists the yield...
Which piping code specifies the high temeperature limt of the following most common used bolting materials? (For valves to be used in ASME B31.3)
ASTM A193 B7, B7M, B8, B8M, B16 ..
ASTM A194 Grade 4, 7, 8, 8M, ..
Thanks
I have received a valve casting per ASTM A351-2003 grade CD4MCu. I performed Positive Identfication Inspection (PMI) and found all the elements meets the ASTM specification with exception of Mn%. Instead of max 1% Mn material that I received has Mn 1.5 % - 2%. Manganise should improve the...
I wondering why ASTM A182 F6 or A276/A479 Grade 410 material is not included in ASME B16.34 material list.
410 grade material has been used as stem material (Stem is also pressire retaining part)
Thanks
I have been performing mechanical test on speciments from the actual product to verify mechanical properties of WCB cast parts. About 50% percent of the test results were lower than ASTM A216 WCB requirements. (within 10%)
I tested the foundry samples for the same heats and found all of them...
I was wondering why there is 1000 F temperature limit on ASME B16.34 for flanged end-connections, but ASME B16.5 does not have 1000F temperature limitation. (Please see foot note on the material tables. Example material group 1.16)
Thanks
Per ANSI/FCI70-2-1991 Class IV shut-off described as 0.01% of rated valve capacity. Test procedure A.
Valve capacity described as “the quantity of test fluid (air or water) that would pass through the valve at rated travel under the stated pressure conditions as determined by the appropriate...
API 10000 16" & 20" Valve
What would be best seal design? (Oring, Oring with backupring, metal seal)
and what is used in the industry for that kind of large and high pressure sealing?
thanks
