The trio finally called it a night with the likely hood of restful sleep a pipe dream.
Branches may be made from the main pipes by means of smaller pipes arranged in the same manner as the mains, the Bolter branch flow pipe being connected with the main flow pipe and returning into the main return.
One end of a pipe is finished flat, the end of the other pipe being brought to a conical edge.
The coiled pipe firebox of the high-pressure hot-water system previously described may be also classed with boilers.
The steam is employed for warming apartments by means of pipe radiators, for heating water by steam injections, and for all cooking purposes.
What is required, however, is something analogous to an organ pipe which produces a continuous sound.
Rostov, smoking his pipe and turning his head about as the water trickled down his neck, listened inattentively, with an occasional glance at Ilyin, who was pressing close to him.
A French corporal, with coat unbuttoned in a homely way, a skullcap on his head, and a short pipe in his mouth, came from behind a corner of the shed and approached Pierre with a friendly wink.
However, on this, the shaded west side, aided by the steady flow from the tapped pipe, massive icicles, bulges and clusters coated the side.
The oldest and best known is the " two pipe " system, others being the " one pipe " or " simple circuit," and the " drop " or " overhead."
The connexion of the return pipe is made with the lower part of the boiler.
The system is hermetically sealed after being pumped full of water, an expansion chamber in the shape of a pipe of larger dimensions being provided at the top of the system above the highest point of circulation.
The one-pipe system is similar in principle, the pipe rising to its greatest height above the boiler and being then carried around as a single pipe falling all the while.
With cast iron pipe this cannot be done, and no length of piping over 40 ft.
Thick, and is stretched on the extreme end of a pipe which is then forced into the next socket.
This joint is durable, secure and easily made; it allows for expansion and by its use the risk of pipe sockets being cracked is avoided.
Io) is designed to allow more freedom of expansion and at the same time to withstand considerable pressure; one loose cast iron collar is used, and another is formed as a socket on the end of the pipe itself.
One end of each pipe is plain, so that it may be cut to any desired length; pipes with shaped ends obviously must be obtained in the exact lengths required.
Radiators (really convectors) were in their primitive design coils of pipe, used to give a larger heating area than the single pipe would afford.
Direct radiators are a development of the early coil of pipe; they are made in various types and designs and are usually of cast iron.
Radiators should not be fixed directly on to the main heating pipe, but always on branches of smaller diameter leading from the flow pipe to one end of the radiator and back to the main return pipe from the other end; they may then be easily controlled by a valve placed on the branch from the flow pipe.
The flow pipe starts from the top of the boiler and is connected near the top of the cylinder, the return pipe joining the lower portions of the cylinder and boiler.
The supply from the cold water cistern enters the bottom of the cylinder, and thence travels by way of the return pipe to the boiler, where it is heated, and back through the flow pipe to the cylinder, which is thus soon filled with hot water.
A flow pipe which serves also for expansion is taken from the top of the cylinder to a point above the cold - water supply and turned down to prevent the ingress of dirt.
From this pipe at various points are taken the supply pipes to baths, lavatories, sinks and other appliances.
All draw off services are taken off from the flow pipe which connects the boiler with the tank.
Taps to baths and lavatories should be connected to the main services by a flow and return pipe so that hot water is constantly flowing past the tap, thus enabling hot water to be obtained immediately.
Frequently a single pipe is led to the tap, but the water in this branch cools and must therefore be drawn off before hot water can be obtained.
In the ordinary working of a hot-water apparatus the expansion pipe already referred to will prevent any overdue pressure occurring in the boiler; should, however, the pipes Safety become blocked in any way while the apparatus is valves.
To prevent this a safety valve should be fitted on the top of the boiler, or be connected thereto with a large pipe so as to be visible.
A water pipe of copper or wrought iron is passed through a cylinder in which gas or oil heating burners are placed.
It consists in sinking a bore-hole, after the manner of a petroleum well, and letting in four pipes centrally arranged, the outer pipe being 10 in.
It is regarded by the Turks as specially valuable, inasmuch as it is said to be incapable of transmitting infection as the pipe passes from mouth to mouth.
Their chief weapon is the blow-pipe, in the use of which they are adepts.
The whole process is exactly analogous to the operation by which a violin string or organ pipe creates an air or sound wave.
The conductors are enclosed in a lead pipe, 24 in.
But, secondly, the pneumatic utterances technically known as speaking with tongues failed to reach this level of intelligibility; for Paul compares "a tongue" to a material object which should merely make a noise, to a pipe or harp twanged or blown at random without tune or time, to a trumpet blaring idly and not according to a code of signal notes.
If the flue pipe be carried up a considerable distance inside the apartment to be warmed before being turned into the external air, practically the whole of the heat generated will be utilized.
From this point the " return " pipe drops, usually at the same rate as the flow pipe rises; and in due course the water reaches its starting point, the boiler, and is again heated and again circulated through the system.
To obtain a larger heating surface than a pipe affords, radiators are connected with the pipes where desired, and the water passing through them warms the surrounding air.
This steam condensing adds to the water in the pipe and naturally causes an overflow, which is led back to the boiler and re-used.
Branches are taken off the flow pipe, and after circulating through coils or radiators are connected with the return pipe.
