Cylinder Manifold
A cylinder manifold is system of pipes and valves for using a group of gas cylinders, or boil-off from vacuum insulated evaporators, to feed a single supply line. The advantages of the manifold In mathematics, a manifold is a topological space that locally resembles Euclidean space near each point. More precisely, an n-dimensional manifold, or ''n-manifold'' for short, is a topological space with the property that each point has a n ... system as compared with using a single cylinder are increased capacity and reliability, and also the possibility of a centralized supply for multiple users. The two main design aspects are use of a banks of cylinder connected in parallel and switch-over among different banks. By drawing from more than one cylinder simultaneously, a greater total amount of gas is available, which means the system does not need to have the cylinders replaced as often. The number of cylinders connected at a time can be varied, and a large supply can be provided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Cylinder
A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called ''bottles''. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus. The term ''cylinder'' in this context is not to be confused with ''tank'', the latter being an open-top or vented container that stores liquids under gravity, though the term scuba tank is commonly used to refer to a cylinder used for breathing gas supply to an underwater breathing apparatus. Nomenclature In the United States, "bottled gas" typically refers to liquefied petroleum gas. "Bottled gas" is sometimes used in medical supply, espe ...

Vacuum Insulated Evaporator
A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications. The purpose of the vacuum insulation is to prevent heat transfer between the inner shell, which holds the liquid, and surrounding atmosphere. Without functioning insulation, the stored liquid will rapidly warm and undergo a phase transition to gas, increasing significantly in volume and potentially causing a catastrophic failure to the vessel due to an increase in pressure. To combat such an event, VIEs are installed with a pressure safety valve. To remain a liquid, the vessel contents must be kept at or below its critical temperature. The critical temperature of oxygen is −118 °C; above this temperature, applying more pressure will not result in a liquid, but rather a supercritical fluid A supercritical fluid (SCF) is any substance at a temperature and pressure above ...

Manifold (fluid Mechanics)
A manifold is a wide and/or bigger pipe, or channel, into which smaller pipes or channels lead. A pipe fitting or similar device that connects multiple inputs or outputs. Manifolds In Engineering Types of manifolds in engineering include: ;Exhaust manifold :An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. ;Hydraulic manifold :A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps ;Inlet manifold (or "intake manifold") :An engine part that supplies the air or fuel/air mixture to the cylinders ;Scuba manifold :In a scuba set, connects two or more diving cylinders ;Vacuum gas manifold :An apparatus used in chemistry to manipulate gases Also, many dredge pipe pieces. In Biology In biology manifolds are found in: * Cardiovascular system (blood vessel manifolds, etc.) * Lymphatic system * Respiratory system In other fields Manifolds are used in ...

Gas Technologies
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listi ...
