This research aims at comparing two different methods for the construction of pressure vessel nozzles, designed with the same safety coefficient, according to ASME and VSR 1995 standards. It defines numerical and experimental analysis of behaviour under low-cycle fatigue for pulsating pressure. In par...

"Water distribution" refers to the water distribution in the working area according to certain rules, the most common is the uniform distribution of water in the working face. The method by which this is accomplished is called a water distributo...
Presently the only vessel in the yards was an old atomic freighter, getting an overhaul and a face lift—a new reactor core, new main engine nozzles, refurbished life-support systems, new paint inside and out. When all the work was done the ship was to be recommissioned and given a ...
Am I right in thinking that the only penalty incurred by the vessel designer/fabricator is a reduced joint efficiency for the nozzle to shell weld, since no RT/UT has taken place? There really is no penalty as the efficiency of the nozzle to shell weld is not used in any calculation ...
Jettison the cargo Should a problem occur of such severity that it is required to jettison the cargo then a special nozzle arrangement is fitted to the manifold and the main cargo pumps started. The liquid is ejected down wind of the vessel forming a large gaseous ball. By carefull design ...
Gravity fed- Toilets operating on a gravity fed flush are the most common. To put it simply, this style relies on the amount of water in the tank and the volume let through the flush valve via gravity to clean the bowl. The way it achieves this is not fixed, but jet nozzles and ri...
Fig.1: Example of a typical Strainer Application of Piping Strainers To ensure against the untimely shutdown of equipment, strainers should be installed ahead of pumps, loading valves,control valves,meters,steam traps,turbines, compressors,solenoid valves, nozzles,pressure regulators, burners, unit ...
Because they do not require electricity, eductors can be used in hazardous environments. Features Eductors use the kinetic energy from a stream of compressed gas or liquid. The movement of this stream through a tapered tube and Venturi nozzle increases the pressure of the flow. The subsequent ...
Upon exiting the nozzle, the melt undergoes a sudden pressure drop, triggering cell nucleation and growth as it fills the mold cavities. The foam expands to fit the mold, remains in place for a specified time, and is then removed when the mold halves are opened. Any excess material around...
