Abstract

A multiple-walled tube or chamber (50) made from cylindrical tubes (11,12,13), having rather thin walls (11,12,13) which are mounted concentrically and welded or fixed on both ends (42), forming a single thick multiple-walled tube which contains round blind slots within the wall, where there are two secured round simple front and back covers (21, 22) and pressure is regulated inside the walls through electric valves (31,32) if necessary. The use thereof is similar to that of HIP - CIP chamber systems but with more pressure.

Description

CHAMBER OR MULTI-WALL TUBE

The isostatic pressure in suitable dimensions, in its maximum levels that is reached by the HIP-CIP method (Hot or Coid Isostatic Pressure); it is still low when compared to other ways of applying pressure, for example; the pressure of compacting between solids that is not possible to apply simultaneously high temperature or the Diamond Anvil Cell that is made only in almost microscopic dimensions.

Nothing is removed by making a duct or a chamber to withstand ultra high isostatic pressure, if we do not have fluid at the necessary pressure to store. Fortunately, a new way of doing ultra high isostatic pressure and simultaneously high temperature if necessary has just been discovered; in appropriate dimensions.

Encased tubes or chambers

A tube with flanged walls, which have an overlap in their diameters in the sense that the internal diameter of the larger tube is smaller than the external diameter of the smaller tube, so that to assemble them the larger tube has to be heated so that it has momentarily greater internal diameter and can be mounted to the smaller tube that is cold and therefore temporarily decreased the diameter.

When they do not have a fluid under pressure, they are subjected to compression in the part of smaller diameter and to traction in the part of greater diameter; but with fluid under pressure, the part with the smallest or largest diameter is subjected to more or less equal traction; in a situation of withstanding more pressure compared to a tube of the same material and the same dimensions of a non-hooped tube.

The negative aspects of the tie-wrap is that the tie-wrap “walls” have no regulation, you cannot change the tension of the walls. In addition, it has a higher cost and a limitation in the dimension of a tube, because if it is too long it is more expensive. Chambers or tubes with multiple walls

The new invention is a simple way that allows increasing the pressure that a tube or chamber supports: A thick, multiple-walled tube is built with concentric thin-walled tubes, welded at the ends so that a tube with cylindrical grooves remains. , blind, inside the multiple wall.

A fluid under pressure can be poured into each slot, into the wall through small perforations that are made and then closed. We have to put more pressure on the smaller diameter inner grooves than on the outer ones; so that when the multi-wall tube has a higher pressure.

Thus we have a multiple-walled tube, equivalent to strapping, but this time the pressure inside the walls can be regulated as the pressure inside the tube varies. If the pressure between the walls of the tube or chamber is not removed, after it has been loaded, it can be excessive and it could break, so it is necessary to have check valves up to a certain value. It should also have inlet valves to the wall grooves.

It can have electric valves so that it is loaded or unloaded at the pressure that is desired; that can be opened or closed according to the relative instantaneous pressure that the particular slot has, connected to a computer; it is possible to have adequate pressure control in the different grooves of the wall.

The incorporation of electric valves introduces a variation in the pressure inside the walls, which can be uniform or as it is regulated; on the other hand, the pressure inside the wall with non-electric valves cannot be regulated. More than that, the tubes will always be at maximum pressure so the chamber or multiple wall tube is emptied if it does not have electric valves.

The assembly of a multi-walled tube or chamber can be of any diameter and length; 1.0 meters in diameter, 100 meters or more long if desired and the grooves that it has can easily pour fluid under the pressure of your choice. On the other hand, a chamber or tube with holed cylinders is difficult to be of such a diameter and so long, due to the difficulties in construction. FIGURE 1 PARTS

Claims

1. Chamber necessary to compress usually at high temperature, used mainly in the metallurgical industry to make metal or food parts; made with tubes of equal length and different diameters (11, 12, etc.), so that one tube fits inside another; that can form a chamber (50) with lids and counter lids (21, 22); computer controlled valves and solenoid valves (31, 32, etc.); a small flexible container (41) having fluid under pressure, normally other than fluid contained in the chamber, outside or inside the tubes; CHARACTERIZED because; a chamber or a multi-wall tube (50) is formed, formed with concentric, thin-walled tubes (11, 12, and more), glued or welded (42) at both ends that can be capped and counter caps (21, 22), leaving blind cylindrical grooves between each pair of tubes, which have an inlet and outlet for fluid under pressure through valves that can be electric (31, 32, and more), which are connected to the container ( 41) in case you have another fluid;

2. Chamber necessary to compress used mainly in the metallurgical industry according to claim 1; pressure is increased with an external pump or compressor, that as fluid under pressure enters or leaves the chamber (50), the electric supply valves are operated inside the wall (31, 32, etc.), that at the end of compression heat can be applied to a solid or sintered part or to a fluid enclosed in a plastic element; with a heater.

3. Chamber necessary to compress used mainly in the metallurgical industry according to claim 1; It is necessary for fluid to enter all the grooves of the wall as the pressure in the chamber (50) increases, because as the internal pressure of the wall increases; increases the ability to withstand more pressure inside the chamber.

4. Chamber necessary to compress used mainly in the metallurgical industry according to claim 1; that can count on another fluid used inside the walls, by electric valves (31, 32, etc.) that join it with a flexible container that contains fluid.

5. Chamber necessary to compress used mainly in the metallurgical industry according to claim 1; that by having electric valves it is possible to instantly regulate the pressure inside the walls, which is not possible with non-electric valves.
