Abstract

The invention comes in the field of industrial piping and Pipeline construction for hot or supercooled pipelines, who do not need to be molested, to use. The invention ha the goal in pipeline construction to a large expansion absorption reach without bending the pipe and the benchmarks far apart to install. It is an O-shaped articulated joint expansion compensator in symmetrical or asymmetrical form, with it by combining several bows and three hinges it is possible to take almost any large longitudinal movements, without that the pipe must be bent in any direction. The invention is used in pipeline construction.

a) Title of the Invention Articular Elbow Expansion Compensator

b) Field of application of the invention

The invention is used in the field of industrial piping and pipeline construction for hot or undercooled pipelines that do not require rolling.

c) Characteristic of the known technical solutions

The prior art is characterized in that there are U-bend and corrugated tube or lens - compensators, which can accommodate only relatively small dimensions with relatively large reaction forces to the fixed points.

Greater expansions at low reaction forces are associated with some known articulating / expansion arches in conjunction with pivots or in conjunction with low friction plain bearings.

The disadvantage of the joint-elongation-arc stabilizer is the necessary bending of the tube during the rotation of the articulated arch, which causes a corresponding additional reaction force and can cause the linings of the tubes to flake off. In addition, a certain free leg length is required for the bend.

d) Object of the invention

The invention has the goal of the greatest possible expansions

without having to bend the tube, thereby attaching the fixed points as far apart as possible, that is, to use as few fixed points for a particular route

e) Presentation of the essence of the invention

For industrial pipelines and pipelines as large a fixed point distance and low reaction forces to the fixed points are desirable because economic.

Large fixed point distances, however, can only be achieved with a correspondingly large expansion capacity of the compensators and slide bearings. According to the invention, the greatest possible expansion absorption is achieved by the grain combination of a plurality of bends and three swivel joints. The bows, in the working position, viewed in the direction of the tube axis, produce an oval or O-shaped view. In side view, it is a V-shape. As a trailer, the known flat and long plain bearings are used. By this combination of bow and hinges a pipe movement (stretching or contraction) is surprisingly possible without the tube must be bent in any direction. Although, compared to the known solutions, an additional hinge and more arches are required, but this is compensated by the small number of expansion compensators within a certain distance and the applicability to all types of lined piping. The invention is explained in more detail in the following embodiment and the accompanying drawings.

f) embodiment

When laying several warming or supercooled pipes over several kilometers with the largest possible fixed point distance _y compensators are with

The correspondingly large O-shaped joint expansion compensator in connection with flat and long plain bearings on the system of low-friction plain bearings is particularly suitable if the lines are not gemolcht.brauchen.

The pipeline is first deflected at the compensator with a 90 ° bend. This is followed by the first swivel joint. Then follow two 180 ° bends and two more hinges. With a 90 ° ~ and two 45 ° bend with an intermediate piece, the pipe is returned to the original axial direction in the off-center shape. This off-center construction is very advantageous for conduits to be laid on either side of a column or along walls. By incorporating the intermediate piece between the first 180 ° arc and the second pivot joint, the O-shaped articulated arc expansion compensator may also be centered, i. symmetrical, shape. Then account for the two 45 ° bend and the intermediate piece at the end. The O-shaped articulated-arc expansion compensator then needs the same amount of space on both sides, i. the pipe lies at the whole distance at a suitable distance from the supports or the wall; All consoles must be correspondingly longer.

However, the outboard compensator requires lateral support in the area of the O-shaped articulated joint expansion compensator, so that the line does not tip over from the plain bearings. For this purpose, under the joints between the first and third pivot and the outer bow low-friction plain bearings are mounted, which slide on the additional support and intercept the tilting moment.

The expansion capacity of an O-shaped articulated arc expansion compensator, and thus the impact point spacing, can be increased by using the flat and long plain bearings, which is extremely economical for industrial and remote pipeline construction.
