Thermosiphon(alt. thermosyphon) refers to a method of passive heat exchange based on natural convection, which circulates liquid without the necessity of a mechanical pump. This circulation can either be open-loop, as when liquid in a holding tank is passed in one direction via a heated transfer tube mounted at the bottom of the tank to a distribution point - even one mounted above the originating tank - or it can be a vertical closed-loop circuit with return to the original vessel. Its intended purpose is to simplify the pumping of liquid and/or heat transfer, by avoiding the cost and complexity of a conventional liquid pump.

You can see this assembly mounted on chemical agitated reactors, they provide cooling to agitators.
Basically principle is density difference... cold fluid has more density than cold one.. this is reason for motion of fluid. eg. solar heaters

An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
A stent is used when blood vessels are clogged (for example, because of a plaque that has grown on the vessel wall. This obstructs the flow of blood, which can have negative consequences for the tissues that are supplied with nutrients by the blood vessel in question. To improve the flow of blood, a stent can be deployed in the blood vessel at the place of obstruction. A stent will basically push the blood vessel open from inside.
Pressure vessel is designed to withstand circumferential load,known as Hoope Stess, but column takes the axial load.
No. There is a specified standard for vessel plates due to safety reasons.

Place a vessel loop twice around a vessel so that if you put tension on the vessel loop, it will occlude the vessel.
The vessel being "overtaken" is the stand-on vessel. The vessel "overtaking" is the give-way vessel.
When a sailing vessel and a pwc are meeting head on the sailing vessel is the stand on vessel.
When the motorized vessel is a commercial vessel or when the motorized vessel has another vessel or person in tow.
The vessel overtaking another vessel
the vessel being overtaken
The vessel that is overtaking another vessel is the vessel that should give way. This means that the vessel that is being overtaken can remain on course.
Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.Dilation of a blood vessel means widening of the vessel.
