Definitions
- Pressure fitting for material flows Method for operating pressure fittings and use
- the invention relates to a pressure fitting for material flows, a method for operating pressure fittings and a use.
- piping systems are used, for example in chemical plants, refineries and power plants, where pumps, apparatus and pressure fittings are used in large quantities. These systems are regulated or controlled, with very different material flows flowing through them, and this under very different operating conditions from, for example, -273 degrees Celsius to +640 degrees Celsius and operating pressures from 0 bar to 800 bar.
- the material streams can be viscous to vaporous and strongly basic to strongly acidic. Very different materials also have to be used for the very different material flows
- pressure fittings for material flows are known from the prior art. As discussed above, these consist of a variety of materials, whereby the pressure fittings have to be tested for material safety in a very complex manner before they are used. In particular, cracks, voids and foreign inclusions have a significant impact on the quality of the material.
- Such pressure fittings are tested using ultrasound, magnetic flux determinations, X-rays and dye-UV fluorescence measurements as well as dye penetration tests, although these tests are complex and therefore cost-intensive due to the often demanding geometry of the components of such pressure fittings.
- the object of the present invention is therefore to provide a pressure fitting that avoids the above-mentioned disadvantages at least to a large extent, so that the time-consuming and therefore cost-intensive material tests can be significantly reduced.
- the pressure fitting according to the invention for material flows (in the sense of the invention the terms "material flow” and “material flow” are identical) has a base body with a pressure-reducing unit, characterized in that a.) between the base body, for example and in particular a pipeline, and the pressure-reducing Unit, for example and in particular a type of sleeve, one Material interruption is realized, and / or b.) between a wall body, for example in particular a pipeline, and the base body arranged inside the wall body, for example and in particular a pipeline, a material interruption is realized.
- the term “material interruption” is to be understood as an interruption of the material flow between the parts listed above, i.e. pressure-reducing unit, base body and wall body.
- these parts touch each other in the context of the invention, either purely mechanically or, for example, and in particular also about welding, but these are always separate parts and not a single part to which the above parts can be assigned in their respective sections and areas.
- these parts do not flow smoothly - as sections and areas of a single part - into one another, but in this sense are separated from one another in a material-technical sense, so that relevant material interruptions are realized, which, for example and in particular, can appear like cracks or gaps when the parts merely touch one another, although these are of course not real cracks which would obviously have negative effects on the material of the respective part, but rather these material interruptions between the individual parts (i.e. pressure-reducing units, base bodies and wall bodies), which look like cracks or gaps.
- the necessary material examinations are generally easier to carry out, since the individual parts can be examined separately before they are later assembled into a pressure fitting, so that complex structures are avoided, which are generally relatively difficult to examine. are to be checked.
- the base body is a molded part and/or b.) the wall body is a molded part, since in this way costs can be saved when constructing a pressure fitting according to the invention.
- the base body is designed to be free of castings and/or forgings, for example as a pressed part
- the wall body is designed to be free of castings and/or forgings, for example and in particular as a pressed part, since such parts are in As a rule, it is easier to examine for material defects, for example and in particular by means of ultrasound measurements.
- the base body When designing the base body as a molded part, many material tests are no longer necessary, since such molded parts are usually pre-tested for certain material qualities. When designed as a casting-free and/or forging-free Although the necessary material tests are not eliminated per se, these are relatively easy since castings and/or forgings are often only insufficiently tested; This particularly applies to ultrasound tests. However, in individual cases it may be advisable for the base body to be cast, forged, pressed or drawn.
- molded parts means components that often correspond to simple geometric configurations such as, for example, and in particular pipes, T-pieces, cross-pieces, bends and Y-pieces and are often also pre-tested for material, although the last criterion is not is mandatory.
- Such molded parts are manufactured in very large quantities, and these are usually - but not necessarily - free of castings and/or forgings. Castings and forgings are generally very difficult to test, and this particularly applies to ultrasound measurements .
- the base body molding and/or the wall body molding is/is a pipeline, T-piece, Y-piece, cross piece, curved piece or a spherical piece. These shapes represent the most common and common shapes of molded parts.

- the pressure-reducing unit can advantageously be made of a tough material, for example Cr-Ni steel, martensitic chrome steel, which is more resistant to cavitation.

- the wall body 8 encloses the base body 1.
- the wall body 8 is generally connected to an external line. There is a cavity between the base body 1 and the wall body 8, for example the inner pipe RLi and the outer pipe RLä.
- FIG. 6 shows a double-walled valve installed in a double-walled system. Firstly, the double line must be routed through the valve and must also include (insulate or monitor) the valve space. Figure 6 shows the outer pipe RLä and the inner pipe RLi.
- the throttling point is changed from the outside using the seat S/cone K and stroke (by positioning the cone K in the seat S; so-called throttling).
- the main position is changed by moving the valve position.
- a valve In a double-walled system, a valve must seal the stroke adjustment (movement of the spindle) very well (for example, tested using a helium leak test).
- Such high tightness values can only be achieved using Meta II bellows, for example 13.1 and 15.1.
- the T-steels used for example (parts 8 and 1), are preferably compression-molded materials - for example, the austenitic CrNi material 1.4580 can be used. This achieves high temperature, pressure and chemical resistance to hydrogen embrittlement.
- the sealing part and sealing element in the pressure fitting As an alternative to the sealing part and sealing element in the pressure fitting according to the invention, it is provided and also advantageous, due to a high degree of sealing between the pressure-reducing unit 2 and the base body 1, that the pressure-reducing unit 2 is held in the base body 1 by means of a press fit, in particular since proven when the pressure-reducing Unit 2 and/or the base body 1 are designed as conical or cylindrical surfaces with respect to their interacting surfaces FW1 and FW2.
