    coupling calc

    Sorry. The rod will travel 22 inches in 30 sec. The max pressure in the cylinder where the piston is will be 7500 psi. It is controlled by hydraulics with a relief set for 7500 psi. Won't be any acceleration.

    coupling calc

    Sorry. Yes you are correct. On the actuator side behind the thick shim there is a retainer washer, has a tab that fits in the key way on the shaft. The two couplings are held together with the fasters, SHCS's.

    coupling calc

    loads go one way when piston downs down then the other way when piston goes up.http://files.engineering.com/getfile.aspx?folder=0b3c6be5-ba91-471d-8ac5-a5e86a8a1e2e&file=Doc2.docx

    coupling calc

    I have shafts both threaded on the ends, piston and actuator, connected by a screwed on coupling bolted together with a shim in the middle. This is for ease of installation and removal. The loads are along the shafts. What is a good calc to use for proper bolt size, coupling mat'l, coupling...

    Measuring steam flow rate

    Sorry. The steam is coming from a turbine. The drain from the turbine I am interested in is supposedly 420 psig @ 470F. It passes thru a 1 inch diameter orifice where it is connected to a condenser at 29 inches of vacuum. The line after the orifice is what is to be measured. Yes there will be...

    Measuring steam flow rate

    The pipe is 4", nom OD is 4.5 CRES316L. The system is designed at 100 psig/275F. It is a steam system.

    Companion Guide to B&PVC VOL 1

    Can the subject guide, 4th Edition Editor K.R. Rao, be used as a respected reference in design papers ?

    Measuring steam flow rate

    Is there a way to measure the velocity of steam through a pipe?

    Elevated heal lot mechanical properties

    Great. Thanks Edstainless.

    Elevated heal lot mechanical properties

    In my case these were certs for flanges made to ASME A182. Wouldn't the flanges retain the elevated properties on the certification papers ?

    Elevated heal lot mechanical properties

    The material is CRES316L.

    Elevated heal lot mechanical properties

    Is there any data suggesting the higher heat lot properties at room temp. will parallel the curve of the mechanical properties of said material at temperatures ?

    BPVC VIII-1 Appendix 2

    You are so correct SnTMan. It doesn't satisfy Apx 2 after going thru that long calc. Guess that will remain a mystery forever. Thanks for every ones help.

    ASTM A182 Heat lots hope this is correct forum

    I have flanges made IAW Subject spec. What is the process to get to these flanges? Is the material cres316l come in big ingots IAW 316L mat'l specs then forged and retested before cutting down? Just want to now cradle to grave.

    SnTman it is B16.5
