How common/safe is it to braze a threaded joint?
Not looking to do it, just curious since I came across a really old piping manifold (30+ years old) that was still in use. Seemed to me like an threaded valve brazed onto a block.
I'm just wondering how common it is, or any pros and cons of doing...
I don't have experience designing plastic parts that mate together, so I'd appreciate some pointers.
Basically I ordered plastic gas diffuser that will be pressed to fit, and I have made the inner diameter of the filter too loose, causing gas to leak from the mating surfaces.
Both diameters I...
Hi All,
I've just made a simple spreadsheet for estimating pipe diameters. Since my application is for gas, lower pressures (<30 bar), short lengths of pipe (<30 metres), relatively low pressure drop, I've opted for a simple Darcy-weisbach equation, coupled with Swamee-Jain friction factor...
Hi All,
I recently came across this problem, though I am not responsible for it, but found it interesting nonetheless.
A chemical plant recently replaced a valve for a cryogenic liquid (ethylene). Previously they had been using a ball valve, but for some reason they chose to use a globe valve...
Hi,
I am in the process of designing some pipelines for gaseous oxygen, and is in need of an actuated shut off ball valve. Typically I would use a pneumatic actuator for this service. However, for this application there are no compressed air or nitrogen available for actuating the ball valve...
Are there any ways to estimate tube/pipe material strength after brazing operation?
The application I am looking may require a section of thick walled H80 copper tubing, and the joins to a brass block by brazing.
I am aware that brazing basically anneals the material, causing it to have lower...
I have used brass/bronze valves on 316L piping before, and the results have generally been good.
However, this time I'll be using it onshore, next to the sea. Anybody have experience with galvanic corrosion in this case? I'll be piping nitrogen. I'm worried about the atmospheric condition. Is...
Hi Everyone, I'm looking for a budget 3d CAD that is simple enough to learn but can do assemblies and BOM generation. I mainly design piping systems, some mechanical parts and assemblies, and also some structural stuff.
As a background: I don't have any experience in 3d CAD, since I never found...
