Dear all,
A very good day to you. I have a confusion regarding heat treatment of welded WPB wrought fittings manufactured to BPV section II Part A: 2017.
When welded wrought fittings of Grade WPB of nominal thickness > 19mm, are manufactured by welding of cold rolled two half plates/shells; is...
Is Welding of A217 c12A cast to A335 Grade P91 possible? What consumbales shall be used? What other critical factors shall be kept in mind while developing WPS?

Table PW-11 as per ASME Sec I: 2017, states that all longitudinal welds are to be volumetrically examined throughout their entire length.
Now. Considering the case of ASME SA 312 welded pipes (welded without addition of filler metal), ASME sec II part A: 2017 does not mandate volumetric...

Why is ASTM A 860 specified as low alloy steel butt weld fittings, even when the chemical composition is similar to A 234 Gr WPB carbon steel fittings and categorised as P number 1 by ASME sec IX QW 422?
Hi all, I have a query regarding thickness tolerance on SA-312 and SA-358 welded pipes.
For SA-312 welded pipes, the under tolerance on thickness is 12.5% of nominal wall thickness and for SA-358 welded pipes the under tolerance thickness is 0.3mm.
Now, as I understand the raw material is the...
Can a raw material certified to an ASTM edition not included in ASME sec II B mandatory appendix II be used to certify finished product to ASME specification.
For e.g Can ASTM SB 425 2010 edition be used to prepare ASME SB 564 2015 edition?
As per ASME B31.1 2014 edition, where is the thickness specified above which PWHT is mandatory for P1 material. In the older versions, 19mm was mandatory. In the 2014 version if I do not meet the exempt requirements , is PWHT compulsory for all P1 material ?
I work in a pure fabriocation company which does not have design of any kind within its scope. CLient is asking for stress intesification factor of Lateral Tee . How do I provide them with SIF data? Material is A234 Gr WPB. Please advise.
I have prepared a TDC for ASTM A105 forged bar. Vendor has supplied material in hot rolled condition. My questions are:
1. Are forging and rolling the same operations?
2. Should the material be accepted in rolled condition?
Nars will be machined into forged fittings. Code of construction is...
Does ASME Construction codes specially B31.1 and section I limit or provide reference to maximum number of PWHT cycles that can be carried out on circumferential welds of A106GrB?
