What is the criterion for deciding the hydro test pressure in relation to the design pressure of a pressure vessel?
It depends on which Directive the vessel has to be compliant with. For instance, to comply with CE/PED, the test pressure shoud be 1.43 times the maximum operating pressure.
What is meaning rating of pressure vessel?
A pressure vessel is built to withstand more pressure than it will ever be subjected to in practice. Such a vessel, after its construction, will be tested to see that it can safely bear far more pressure than it needs to bear while doing its normal job. I used to play hockey with a chap who tested such vessels. We called him the "Boiler Buster".
What is the difference between ASME U and U1 stamps?
The ASME U stamp designates an unfired pressure vessel of more than 35 gallons (4.68 cu. ft.) has been built to ASME Code specifications, under ASME Code section 8. A U-1 form must be filed and signed by the authorized inspector for each and every pressure vessel built. The ASME U2 stamp is for unfired pressure vessels not built to ASME section 8 div. 1 standards, but under the alternative rules, has been inspected and found to comply with acceptable construction methods. A U-1 form signed by an authorized inspector must be filed for each such vessel, along with a description of the methods of construction used. The ASME U3 stamp is for high pressure (over 600 psi?) unfired pressure vessels. The ASME UM stamp is for pressure vessels less than 35 gallons capacity.
Name 11 factors that should be considered when selecting a material for a product?
The temperature in a vessel is 36 degree C and the proportion by mass of air to dry saturated steam is 0.1. What is the pressure in the vessel in bar and in mm of mercury vacuum? The barometric pressure is 760mm Hg
How you can find the thickness of pressure vessel diameter is 4.6m and length is about 19.2 meter and working pressure is about 16.5 bar?
Measure external diameter. (A) Measure internal diameter. (B) Subtract B from A
What is difference Between Vessel Column?
Pressure vessel is designed to withstand circumferential load,known as Hoope Stess, but column takes the axial load.
What is the difference between steam boiler and pressure vessel?
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
What is the difference between vessel and drum in chemical engineering or petroleum industry?
I think a vessel is containing a fluid under high pressure whereas a drum contain a fluid with no or low pressure.
In the body where does the driving pressure for fluid flow come from?
The pressure difference between the two ends of a blood vessel is the driving force behind blood flow.
What is difference between pneumatic test and air test in pressure vessels?
Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
What is the difference between motor ship and motor vessel?
There is no difference between the term "motor ship" and the term "motor vessel." The two are commonly used interchangeably.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.

What causes the transfer of materials between capillaries and tissue fluid?
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
What is the difference between the terms burst pressure and working pressure?
Working pressure refers to the maximum safe *operating* pressure. Burst pressure refers to the actual point at which the vessel containing said pressure will fail. Operating pressures normally have a "buffer zone" between itself and burst pressure, to insure no sudden spikes or variations cause failure leading to injury.
Why two psv installed on column or vessel?
PSV stands for Pressure Safety Valve Both of them are set at slightly different pressure settings. If the pressure in the vessel is too high it will trigger the PSV with the lower setting first. If this is not sufficient, than the second one will open. Just like a failsafe.
What is the surface area of a pressure vessel?
The answer depends on the pressure vessel.
