Designing pressure vessel

AI Thread Summary
Designing a horizontal pressure vessel with twin saddles that is not symmetric poses challenges under the PD 5500 code, particularly since Annex G primarily addresses symmetric vessels. Participants in the discussion seek alternative methods or insights for adapting the design principles to accommodate asymmetric shapes. The ANSI B31.1 code is mentioned as a potential reference for additional guidance. The conversation emphasizes the need for innovative approaches to ensure compliance with safety and structural integrity standards. Effective design solutions for asymmetric pressure vessels are crucial for engineering applications.

Hi

I was wondering how to design the horizontal pressure vessel on twin saddle that is not a symmetric shape using PD 5500 code.

For example, Annex G of the code shows how to design with twin saddle, but it is only approach with the symmetric pressure vessel.

Anyone has an idea or any approach on this ?

Thanks.

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
