SnTMan, Thank you for responding with suggestions of where to look in Code Book. The requester finally comprehended that spending my time performing calc's for a part that may not even be available at a reasonable price was not the best use of anyone's time. GD2, Yes, I was given a task to...

Vessel Material is Carbon Steel, the Design Code is ASME Section VIII, Div.1, and yes the Swage is to be welded. I was throwing this out there to see if anyone has ever come across a Swage Nozzle of this size. We can not use a 30 x 36 conc. reducer due to process flow requirements. The...

Several questions below, Has anyone ever designed or fabricated a 30" Swage/Transition Nozzle? I've been directed to determine the minimum Vessel ID needed to attached a 30" 600# flange using a Swage/Transition Nozzle. I can narrow that down to 38" ID min., because that's needed to meet other...

My original post included an attachment showing the Swingbolt design. This design requires a washer to provide a surface for the Nut to seat against. Very Similar to a Tube Turns T-Bolt Closure. I've been questioned why we aren't providing washers made from materials listed in tables UCS-23 or...

What is the best way to determine what specification/s a washer needs to adhere to on an ASME Section VIII, Div.1 pressure vessel? Is there anywhere in Section VIII, Div.1 stating carbon steel washers SHALL be made from material listed in Table UCS-23 or Section II materials? The washer isn't...

I have a question regarding whether or not a Flanges made from 3/4" Plate rolled into a Ring, used in a design rated for 500 PSI @ 200°F can be designed as a LOOSE Flange. Years ago we were directed to design all flanges used on designs with pressures greater than 300 PSI as an Optional...

I agree, but several other co-workers believe that when using an O-Ring seal "G" is equal to "Go". Please note my original post incorrectly stated 2-5(c)(2), it should have read, 2-5(c)(3) To support their belief they reference the information in our PV Elite Software printouts that state that...

When designing a flange with an O-Ring seal, which is 31" OD x 30.45" ID with a 0.275" C/S, should the "G" value be determined as stated in 2-3, or, should the "G" value = the OD of the O-Ring as noted in 2-5(c)(2). Example: If using the 2-3 definition of G, and assuming that "N" from table...

Thank you for replies. After further review the customer has agreed to another nozzle layout that suits their needs for less cost.

I'm looking for help with finding the proper way to calculate reinforcement for (2) 12" tangential nozzles that are going thru the knuckle of a 48" Ellip Head, into the shell & thru the head to shell seam, and are parallel to each other. One of the nozzles is set on and the other will project...

FYI..... I've found out that the plugs are coming from Bonney Forge. When I insisted we needed to see their documentation I received a memo form a Bonney Forge Product Engineering Manager dated March 17, 2017 which stated..."Bonney Forge 1" hex head plugs and bushings have been redesigned for...

I agree, they're most likely not B16.11 plugs. Our description clearly states we want Solid plugs supplied in accordance with B16.11, but the purchasing person who's in touch with the supplier appears to not comprehend this part of the requirement. I explained to the purchasing person, it's...

We have a vendor asking if we'll accept pipe plugs that are solid up until the threads but hollow where the threads are. I looked at ASME B16.11 and it appears hollow plugs are not addressed. Has anyone accepted these types of plugs and if so what justification was used to qualify them to...

Thank you for the replies. The pressure vessel is on a ship and they want us to perform the hydro test. I was hoping to avoid this by drilling & tapping the vent connection directly into the cover flange, but the lift lugs have to be welded so there's no escaping the hydro requirement. We will...

Our Customer has requested a replacement cover for an ASME Section VIII Div.1 U-Stamped pressure vessel., supplied by our company. The cover is a blind flange designed in accordance with App.2. Welded to the cover are 2 lift lugs and a vent coupling. I believe the cover assembly needs to be...
