Hi all, does anyone know how can I do to obtain a firetube thickness by API 12 K? thank you, JJG

Hi, I’m looking for a material to my Reboiler. One option is an IRAM F24 or F30. My question is if anyone can tell me the tensile stress of these materials. Thank you, JJG

In API 510 7.2.10.- said: “Substituting nondestructive examination procedures for a pressure test after an alteration may be done only after a pressure vessel engineer experienced in pressure vessel design and the authorized pressure vessel inspector have been consulted.” How can I contact an...

Yes, but I am looking for another alternative, my intention is obtain the acceptation for API 510 of this welding.

The alteration is not a reinforcement, in fact, the nozzle doesn’t need a reinforcement. I am talking about a replace of the original welding. The problem is that the new weld procedure isn’t exist.

the vessel was designed by ASME VIII Div.1 1998 to 2000

Helo, I have to rerating a pressure vessel which was alterated by welding in one of its nozzle. API 510 section 7 show the details to doing the reparation and rerating. Can I do the rerating if the welding was done without following the instructions of this section? In 7.2.7 (Design) mention a...

Hi, Does anyone know which is the standard for calculate the minimum wall thickness of a boiler (glicol regenerator)? And which standard I have to use for evaluate a weld defect in it´s fire tube? Sorry about my English and thank you.

Hi, I have one more question, does anyone know if ASME VIII has some recommended practice which says that the required area of the nozzle would be obtained using the MAWP of the selected flange instead of the design pressure? Thank you.

I was looking for some information in ASME B16.5 and I found a reference of a “Pressure-Temperature Rating Table” (in table 1A). The material of my flange is an A105, so, when I go to the reference table (2-1.1) I obtain the working pressure at the working temperature. I was wrong when I said...

Hi, I am doing a Rerating of a pressure vessel; my problem is that I don’t know the grade of a flange (Class 600). Does anyone know how can I do to obtain this information (consider that I haven’t got documentation of this flange), perhaps some geometric characteristic of the flange? Thank you...
