Some people always said, "Just do it, don't ask!!!"

It is really a very high temperature, can you tell me the real application in such high temperature?

Thanks for all suggestions for the high torque required for triple offset valve. On the other hand, my client found out and complain to me that the screws in the ring (seat retainer) are not strong enough to hold the seal. What can I do? Any formula to calculate the sizes or number of cap screws...

I suggest the magazine "Machine Design".

Jim, Your explaination is so detailed. I learned much from you on valves. In fact, I work as distributor, one of my clients complain the triple offset valve need to have a larger torque to have a bubble-tight, compared with double-offset. Do you have any idea how to reduce the torque? Thanks a lot

Please use the notepad in windows.

I just got my result. Luckily, I passed with 87. Thank you for all people here.

If your degree is not on the list of the Washington Accord, you need thew double time to obtain your license. In my state, TX, eight years working experience are required to obtain the license, while the ABET one is four years only.

Anyone knows the costing of living, house price of the Austin, Dallas and Houston in TX?

Dear all, My company also consider to do some CFD model on the gate valve? Do anyone know the price for the CFD package, such as fluent or CFX? James, How much for CFD package produced by Harvard Thermal Inc.?

u use abaqus or ansys?

Thanks Bruce, It seems the graphite is strong for the high pressure case. How about in the cryogenic condition? The graphite in triple offset valve is still working? My client find his valve is leaking for the liquid nitrogen condition, extremem low temperature.

I would like to know where can I find the college which provide provide such part-time courses. Thanks.

Anyone know the graphite in body seat can survive in the high pressure class (such as ANSI 900)and the high temperatue cases.

So, why many people said we don't have enough engineers in the future compared with other countries, such as China or India. How can we persude someone to be engineer if we don't have a job for them after graduate. Oh My god!!!
