Hello all,
I hope someone can help.
a) According to NF A 36-205 (Edition 1982) Plates A 48 exist in three variants AP, CP and FP .
If a certification after heat treatment is necessary, a guarantee can be given and the three variants are followed by an "R"
(ex. A 48 APR, A 48 CPR and A 48 FPR) ...
Hello metengr, thanks for your answer

Sorry but I have read once more section 3 of SA-325 (Metric Edition 2010 Addenda 2011 - Page 510) without finding something about my question...

Hello everybody,
Point A
According to ASME 2 Part D, SA-325 Type 1 can be used up to 343 °C .
Is this temperature valid for both Plain (noncoated) and Zinc coated finish types ?
Point B
ASTM A-490 has no ASME equivalent (SA-490 does not exist).
What is the maximum temperature to be applied ...
Thanks a lot for your answers.

In order to avoid any wrong interpretation how can I write inch values in a table ?
General Example (particularly Excel use)
1 1/4"
1 2/5"
1/2"
3 1/2"

Answer for XL83NL
Your approach is correct and corresponds to the requirements of EN 287-1 (Edition 2011) :
a) Confirmation of the validity > see paragraph 9.2
b) Prolongation of qualification (every 2 years) > see paragraph 9.3
Answer for XL83NL.
With your NoBo you have taken a good approach to fulfill a lack of precision from EN 1418 .
In my opinion a better solution would be to fusion both documents EN 287-1 with EN 1418...
Hello Aburafdi,
1) In my opinion, EN 1418 is not precise enough and lend to confusion. As mentioned in my previous intervention 23rd January [b] = EN 287-1 paragraph 4.2 process 121 is defined as "PARTLY MECHANIZED" that means 121 process should not be mentioned at all in EN 1418...

Reply for MM Praktiker and SJones:
In my opinion, we should only qualify our operator according to EN 287-1 for the following reason :
Referring to EN 287-1 (2011 Edition):
a)Paragraph 1 Scope last paragraph :
"Fully mechanized and automated welding processes" are to be qualified according to...
In my opinion, your Procedure Qualification Record in a but joint qualifies all Filet welds as stated by Table QW-451.4 .
See in QW-451.4 "Type and Number of Tests Required" .
Particularly read paragraph QW-202.2 > (c) .
Sincerely,
Hi all,
According to EN 1090-2 "...Technical Requirements for Steel structures", we have to qualify an operator in an automatic process (SAW - Submerged Arc Welding = 121 ).
Both Operator-qualification documents EN 287-1 and EN 1418 are referenced in EN 1090-2.
In our opinion, the Operator...
Hello SnTMan,
1) In my opinion it would be a mistake to accept pipes SA-789 # S31803 without Heat Treatment and a Non-conformity to ASME 2 Part A Table 1 requiring a Heat Treatment of 1020-1100 °C .
The required Heat Treatment can not be done after welding...
2) Remark : After Welding neither...
Hello sjl228,
As you can see :
1) in ASME section 1, PG-5 to PG-10, SA-358 specification is absent;
2) in ASME Section 2 Part A Table ED-1, SA-358 is not allowed for ASME 1 .
3)In ASME section 2 Part D Table 1A, SA-358 is not allowed for ASME 1 .
4)In ASME section 2 Part D Table 1A, SA-358 is...
Hello hacksaw,
Do not forget what the requirements are :
a) Governing Code = ASME B-31.1
b) Environment = Wet environment (see attachment)
c) Choice of the Base Material + Is Stainless steel material (A182-F316H) acceptable ?
Remark : 1) I have PTC 19.3 TW (2010 Edition) which is not giving...
Thermowell Stainless steel material in wet environment according to ASME B-31.1 (up to 2010 Edition) .
Question 1 : Is Stainless steel material (A182-F316H) acceptable for use on Boiler External Piping at Temperatures of 316 °C max. ?
Remarks :
In my opinion, ASME B-31.1 does not mention this...
