Dear MJCronin, Thank you a lot for your interaction. That's right, "T&P Class Ratings" of the ANSI/ASME B16.5 and 16.34 standards are for specific group of materials, but appendix B in ASME B.16.34 offers the possibility to calculate the "T&P Class Ratings" for unlisted materials such as...

Does anyone have any insight into this? Thanks

Hello everyone, I have received a request from a customer to design a valve according to ASME B16.34 ,made of titanium (pressure class 300). If we look at the pressure - temperature tables of ASME B16.34 we find out that titanium has not been processed. If I look at appendix B, in which the...

Hi everyone, I have two questions: What is the difference between working pressure and ceiling pressure in asme b16.34? what is the ceiling pressure used for? Thanks for your time

Thank you very much We can calculate the The minimum wall thickness according to ASME B16.34 with Table VI-1 Basis Equations for Minimum Wall Thickness and Table 3 Valve Body Minimum Wall Thickness. But ASME B16.34 is saying nothing about the bonnet thickness. Please see attachment...

How can i calculate the minimum bonnet thickness according to a standaard? which standaard? Thanks

Hallo everyone, Wall thickness requirements for valve bodies are specified in para. 6.1. The minimum wall thickness values, tm, shown/calculated in: 1. Table 3 2. Wall thickness equation of Mandatory Appendix VI 3. Wall thickness equation (B-1) of Mandatory Appendix B ASME B16.34...

Thank you very much for your relevant information’s I learned last days that is also possible to design a monoflange according to ASMEB16.34, by using paragraph 6.7 in ASME B16.34 for wafer or flangeless valves. The monoflange valve appears to be this type of valve and if it complies with the...

I don’t know how to thank you. You helped me so much 🙏 You’re the best!

Could you please help me with this issue? Paragraph 6.7 shows that a flangeless valve shall conform to the applicable requirements for flanged valves and the requirements of Paragraph 6.7. I don't see a specific paragraph about flanged valves, only paragraph 6.2.2 Flanged Ends. The...

This is very important information for me. Thank you very much 🙏.

In the process applications is a high response speed required for the most control applications. One of the variables that affect the response time is the volume and the distance between process and pressure sensor. This why a monoflange is an interesting solution to connect the pressure sensor...

Thank you very much for your explaining!

I am confused because i see some Monoflange manufacturers saying that the monoflange has been designed according to asme b16.34 https://www.baltic-valve.com/asme-b16-34-monoflange-dbb-valve-a182-f316l-1-2in-600-lb-rf-npt.html

Hi everyone, Asme b16.34 covers valves with flanged, threaded and welded ends. Can i consider a monoflange as a flanged end valve according to asme b16.34? Thanks in advance for your time.
