I have a sheet metal tube with a circular cut on one end. such as if you inserted a 3" tube into a 6" tube at an angle of 30 degrees. Off the axis of the 6" pipe. so now the 3" pipe has a cut that follows the profile of the 6" pipe. A typical y intersection. I now want to take that 3" pipe and...

I'm trying to develop a Mass spec leak rate for a high pressure valve. (3000-3200 psig) We are allowed a mass loss rate of 0.0015 grams/hr. (nitrogen) I would like to convert that to scc/sec nitrogen and then to scc/sec Helium leak rates. Once that is accomplished I need to develope a...

We are having a discussions as whether it is better to passivate before or after performing final Lap / Polish of a metal seat. Material 300 series CRES, min 8 finish. we perform the lap in house but the part is machined and passivated prior to our reciept. Is there any spec that stipulates...

Does anyone have a simple process to test compressive strength of soils in the bottom of a post hole, dug for an attached deck. Building codes are dictating a 20" minimum hole size unless comrpessive stregth of the soil is determined. Thanks Gary

I'm looking for a suggestion for a ceramic insulating plate. I'll be using the plate on a 3" x 60" aluminum plate heated internally by an element to about 500F. the plate will be about 1" thick. along the lower 1" of this plate's face I'd like to attach a 1" x 60" long strip of ceramic plate. My...

We have solenoids that we purchase from a manufacturer. They perform Insulation resistance and Dielectric testing IAW a define test procedure. We then send the assembly out into the world for use. We occasionally receive the product back from various airlines to be retested and recertified for...

I am trying to update our ball-valve ball specifications. I need to provides specifications for a 1.0" dia ball made of 316 SS. We currently called out 100v (valve grade balls) but there does not seem to be a specification for valve grade balls. We require a 3 Rma surface finish, with a...

Am I missing something? Is there an easy way to create a custom sheet format with out modifying and saving the out of the box examples provided? I'm hoping to just open an existing Acad dwg Title block, and save it after conversion as a slddrt file. Thoughts? Falcon4

I am currently looking for suggestions for a Ball-valve, ball supplier. We have current suppliers with poor quality ratings. We currently procure .50 DIA and 1.00 DIA valve balls machined to various geometries. (Leave ITC out of your suggestions) Thanks Gary

We currently have valve seats machined from extruded Nylon 6/6 rod. We are investigating the possibility of having these molded. Our concern is the change of physical properties that may occur. Does anyone have information on this subject. Thanks, Gary

Can external threads (e.g. threaded end of a shaft) be added as part of the model, like adding threaded holes?

Is it possible to insert and orient an axis or user coordinte system with angles relative to the initial x,y,z axis? I have a part machining axis that is set relative to X,Y,Z. But I cannot figure out how to specify these relations.
