I manufacture ceramic parts from fiber, silicon carbride and cement. Once parts have been processed I need a good reliable hardness tester. has anyone used a hardness tester(vicker unit) for testing ceramic materials. I would like to know what unit you have had success with. This is going to be...
I am trying to find a supplier to manufacturer 2 identical eccentric cones. Material is SS316L and customer will allow one piece rolled/welded eccentric cone or machined. My problem is that I need 6.35mm wall thickness due to temp and creep rate. The small ID is 5.1" and large ID is 9.5". Piece...
I am working on creep rate of ss316L pipe and I need to find mtr material thinning rate for this material. Does anyone know where to find this for temperature approximately 600C. I saw this in a chart several years ago but did not save like normally would. Now that I need it, I can not find it...
I am going to make a SSseamless pipe at 1.5" sch40 into a flow meter and I need to change the cross section shape. I intend to flatten pipe to about 1/2" height for fluid to pass through. When I do this, I think I am going to have a bit of a problem. I think the rating of the pipe for pressure...
I ahev a test loop that I am trying to determine accurate flow rate of liquid sodium in loop. I made the magmeter and it outputs millivolt signal. I have purchase GE ultrasonic flow meter to calibrate my magmeter. I need to calibrate 200, 325 and 450C flow curves. I am done with 200C but to do...
I am using a GE ultrasonic flow meter that measures flow through 2 ultrasonic transducers. I have never used one like this before and it works good until the flow rate gets toward top end of scale. It is suppose to measure 650gal/min and I can not get above 425gal/min. It is showing signal...
I have a large piping test loop, 4" sch.40 SS304 that holds 20 gallon of fluid. I am using a very dangerous fluid and can not afford a leak. I first pressure test and have no leaks. Then heat piping to 200C and then vacuum test. I can pull a 1950 microns and when I disconnect vacuum I do not...
I am working on heat removal utilizing forced air. My goal is to find cfm volume necessary. I will push air via cent fan through a pump and do not know how much heat the coils give off as it is just being designed. We have calulated coil mass and current draw. I need a good formula for heat...
