I know of one standard that addresses this - API Spec 16C. During equipment tests, it requires that measurements be made in the range of 25% to 75% of the gauge full scale deflection.

Thank you for the help.
unclesyd: I am referring to a thermal spray/metallizing process. I do not know any more details about the process - yet. The diameter is approximately 3 inches.
Thanks again.
I have a shaft made from cast 316 SS which has been machined undersize approximately .035 inch. The undersize surface is used to support a roller bearing. It has been recommended to buildup this surface by "spray welding" and then re-machine to the correct diameter.
Is spray welding the...

You might look at Armstrong A-2 and A-706 epoxies. They are both basically the same, but A-706 has a 400 degree F temperature limit and it is a bit harder to work with. A-2 is very simple to use. Good luck.
Hello:
I frequently see the terms “macro” and/or “micro” on material certification reports. What do these terms mean?
Are these terms related to a UT inspection?
Thanks in advance for the help,

Getting back to tc7's concern, how about using the NPT thread dimensions that correspond to the hand tight plane (or even the wrench tight plane) to calculate external tensile stress area, external shear area and internal shear area? From this, the applicable stresses (and thus strength) could...
Why then, are the Parker and SwageLok books full of items with NPT threads that have a static operating pressure greater than 3,000 psi? Numerous fittings with NPT threads shown in these books have ratings in the 8,000 to 10,000 psi range. Based on these NPT thread ratings from fitting...
Hi:
Could someone please give an equation or cite a reference that discusses open channel flow where the liquid in the channel is not water.
I need to determine the flow capacity of a channel that conveys fluid with SG > 1 and maximum solids content of about 20% with the maximum solid size...

The dead and live weight (approx. 1000 klbf max.) of a piece of equipment will load the top flange of the beam. The load is distributed over a beam length of about 15 feet. My beam (W24x55) is being used as a support for this equipment. The footing of this equipment is such that the...
Hi:
I’ve got a W beam with the top flange subjected to a compressive load that’s distributed over the length of the beam, and I am checking to see if web stiffeners are needed. The ends of the beam are restrained from rotating. I’ve checked for web yielding and web crippling per 9th edition of...
