As I was searching through the different treads of this forum, I found some good info regarding the bake-out, but there was not much discussion on the practices. I would like your opinion and advice on the bake-out temperature and time. So far the mnost common are the temperatures between 200°C...
Hi guys,
I found some conflicting information in the thread #177-44286.
Can anyone, who is in posession of pre 1962 ASME check for me the allowable stress value for SA-212 B in room temperature?
Thank you kindly.
Putting Human Factor Back in Engineering
Dear Engineering Friends.
I am currently reviewing a vessel manufactured in 1960. The markings on the nameplate below the ASME "U" symbol read: W; PXR; SR.
As you very well know only the W (for arc or flame welded) meets current Code.
The remaining two acronyms stand probably for X-ray level...
Hi Guys,
We have a couple of vessels manufactured. One of the requirements is low stress stamping of the plates. All the welds are ground flush because of cyclic service and it does not make sense to have those solid stamps punched in the plate surface while we remove all the traces of...
The reactor vessel has been manufactured from 1.25%Cr 0.5%Mo weld overlayed with type 347 stainless.
I don't have information about the process conditions other than design temperature 420°C.
I am in favour of pickling and passivation after PWHT.
What is you advise?

Could any of my esteemed colleagues guide me to Code interpretations for ASME VIII Div. 1 UCL-34? Just the number, please I will find it than.
I would also like to know your interpretation.
1. Does the paragraph deal with PWHT to relieve the stress after corrosion resistant weld overlay...
1. Is ASTM A519 Gr 4130 an acceptable material to fabricate the fittings in accordance with ASME B16.9? To my knowledge it is mechanical tubing and should not be used for pressure applications. Is this correct?
2. What are the requirements for that wrough material to comply with ASME B16.9?

I have seen a note in one of the forums (fora?) about an error in UCS-56 of 2004 edition of ASME VIII Div.1. Unfortunately I could not trace that information so I place this note for all my coleagues.
The PWHT for P1 material shall be 1100°F not 1200°F as specified. ASME is apparently intending...
Hi all.
One of my client specifies that the PWHT temperature for 1 1/4 Cr 1/2 Mo shall be 50°F lower than the tempering temperature.
That spec was not available initially to the fabricator and they worked out their material and fabrication heat treatments: PWHT was set on 1275°F and the...
Hi
Can anybody advise me on possible applications for the F43 filler on ASME boiler and B31.1/B31.3 applications;
- SA-213-TP304H to SA 213-T22
- SA-213-TP347H to SA 213-T22
- SA-213-TP321 to SA 213-T11
- SA-213-TP321-H to SA 213-T22
- Tube to Tubesheet weld. SA-213-T22 (tube) to...
Hello.
I have been requested by my client to perform the hardness survey of carbon steel piping weldments intended for sour oil service.
The test shall comprise of parent metal, weld metal and HAZ measurements.
My old trusty, portable telebrineller is not acceptable to my client due to the...
