FORGINGS A105 OR A36 -WHICH IS SUPERIOR? - Eng-Tips
2001年9月25日 · A collar is similar to a flange except that there are no bolt holes. The collars are connected by "quick release couplings" The material specified for the collar is A36.Most of the forging vendors do forging with A105. My question is-which is a superior material for this work A105 or A36.?
ASTM A105 vs ASTM A181/1 Flange 1 - Eng-Tips
2017年1月1日 · 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.
A105 and A216 GR WCB , PLease help !!! 7 - Eng-Tips
2001年11月27日 · ASTM A105 and A216-WCB (or their ASME SA equivalents) are two different product forms. A/SA105 is a forged material specification while A/SA216-WCB is a cast material specification. The chemical composition for each material is essentially the same (low carbon steel) but there may be some very minor differences in exact ranges of minor elements.
A105 vs. A216 WCB valve material - ANSI (standards) Code Issues
2010年7月13日 · SVI answered this one pretty well. The only thing i would add is that, in my experience, A105 is generally used for small bore valves. A216 is for larger bore valves (> 2"). Service fluid, conditions and customer preferences should all be taken into account, here.
A105 Flanges used in place of A694 5 - Eng-Tips
2014年5月8日 · Bottom line, a A105 flange with 42ksi SMYS can be used with a X52 SMYS pipe. The ideal situation would have been to use the A694 with matching SMYS and therefore, same weld end thickness. Had A694 used, the other job would have been to find the P-T rating of the flange at design temp when it came to testing as A694 is not listed in B16.5 tables.
ASTM A105 what does it mean? - ASME (mechanical) Code Issues
2002年8月7日 · A105 is a forged carbon steel, it's like C22.8 except some slight difference in chemical composition especially with Carbon. In absence of an european equivalent grade, I assimilite it to C22.8. According to our experience C22.8 can be equivalent to LF2 also (contrary to A105; A105 can work down to -20°F(-29°C) and LF2 to -50°F(-46°C)).
Is Impact testing required for ASTM A105 special forging?
2008年5月16日 · I'm working on a carbon steel vessel with MDMT of -24degree C, the shell material is ASTM A516 Gr70 and the forgings/flanges are A105. I understand ASME B16.5 flanges are excepted from impact testing up to -29degree C. I've got a heavy neck forging of 152.4mm thk welded into the 35mm thk plate.
a105 instead of a694 - ASTM (testing materials) Code Issues
2015年7月3日 · A105 & A694 are both forging material. A105 is CS forgings, A694 is carbon and alloy steel forgings. A106 is for seamless CS pipe. Either way, you'll have to check the code to see what is allowed. Is this question just out of curiosity or is there a reason you're trying to replace A694 with A105? "Tell me and I forget. Teach me and I remember.
ASTM A105N vs A105 for Globe Valve Body - Eng-Tips
2010年2月23日 · API RP14E: Para. 4.1 (b) specifies that A105 material should be normalized for service temperatures below 30 F (-1 C). ASTM A105: The ASTM specification itself requires all flanges for service greater than ASME Class 300 be normalized as well as all piping components other than flanges, which are NPS 4 or greater, and intended for service in ...
Charpy Test for grade A105 - Metal and Metallurgy engineering
2008年7月16日 · There was a technical paper I came across with the subject of brittle fracture in A105 flanges. I have a copy of the paper in my files; "Susceptibility to Brittle Fracture of Flanges in ASTM A105"by A. Dhooge and E. Deleu from the Belgium Welding Institute (BWI). This is a decent paper on the problems with A105 and not having a N or Q&T hea ...
