I have a flanged ring test piece that will be bolted to a pressurised item, to hydro test it in workshop at 1630psi with water, prior to return the pressurised item to service after rebuild. Less than 100 uses through life.
What are the requirements for initial test of the flanged ring test...
Not sure simple 2-D FE will take on this problem which is one of instability rather than stress level. Have Roark 7th and couldn't find square tube in the chapter 15 on instability.
Found a thread on internal pressures in rectangular tubing (thread 794-123788). The piece on vehicle frame air...
Not a true piping question but I have been asked to look at a small fabrication in 50mm square by 3mm wall structural hollow section that is to be immersed to about 1500 ft seawater ie assumed 50 bar hydrostatic pressure.
If the calcs can show the tubing will resist hydrostatic collapse with...
Does anyone know of a valve for automatically shutting off water pressure in the event of downstream line (hoses, fittings etc) failure. The application is for water for a test rig at up to 6000psi with small diameter hoses (equivalent to half-inch). I have heard of such devices on fire hydrant...
