Field of the Invention

The present invention relates to an insulating module according to the preamble of claim 1, and in particular to the interconnection of such modules.

Background of the Invention

A variety of custom-built pipelines or pipelines are used in the prior art, either for process purposes or for use of the plant itself or for transferring the end product to customers or other actors in the logistics chain. For example, heating plant 10 uses pipelines to transport fuel to a heat generating plant and to remove waste, such as exhaust fumes. Further, the heating plant has special pipelines, for example for cooling and lubrication, and for transferring the heat generated to the final customer to customers, for example, via district heating pipelines. The oil and gas refineries also have pipelines for the transfer of raw materials and for storage of products from industrial processes, as well as various cooling or heating pipelines, all of which require at least partial containment.

All sites are subject to similar needs, as well as the specific characteristics of the sector, to technically isolate some areas of the pipeline from their environment. Such needs include, for example, fire protection. thermal insulation of pipelines, cold insulation and other special insulation required for process operation. Occasionally, there is a so-called need for PP insulation, or Personal Protection • *; the need for safety insulation to ensure occupational safety.

'· ·' 25 The isolation of the pipelines naturally also necessitates the periodic access to the piping underneath the surrounding insulation to carry out the necessary monitoring, maintenance and repair work. On the other hand, there are many objects where the insulation of the pipelines has to be repeatedly removed. -,: temporarily so that, for example, weld seams and pipe clips are in good condition

30 reviews could be carried out periodically. Similarly for piping and piping. any special coatings and actuators installed on them, such as valves and pumps, require frequent inspection and maintenance.

1: '': In addition, for various reasons, it must often be possible to use manholes and inspection hatches in piping and under insulation, and to have access to 110814 and inspection of tanks associated with piping. Especially in the industry, various process equipment related to piping has to be replaced, which also requires working space, ie removal of insulation around the piping. Removal of insulation will also require inspection of filters in the piping and 5 replacements or even installation of completely new equipment in the piping. In addition, various authorities and classification societies impose their own requirements for pipelines and related equipment to be inspected as necessary or even periodically.

Conventional piping insulators thus comprise 10 different insulators made of insulating material which are substantially fixed to the surface of the piping or insulating pieces secured to the surface of the piping by means of various bandages or other means. Also known are moldings used as insulation which, when mounted around the piping, are locked together by various locking means 15 and protruding from the outside of the body. Such are disclosed, for example, in GB 1 369 283, US 4 225 307 or US 4 312 385.

However, these known solutions have had the problem that the removal or dismantling of the insulators made with the materials and techniques in use often leads to breakage or damage to the insulators, which significantly shortens the life of the insulators and thus increases the cost of insulating the piping. Conventionally, the insulation provided on the surface of the piping is to a large extent removed, which is laborious and thus expensive. This type of insulation will be damaged when it is removed, which will further increase the cost of installing new insulation at the end of maintenance or repair work. The handling, transfer and storage of insulators are also problematic for current solutions, which are usually of considerable size. Insulators which are fastened to the pipelines with banding belts often also break when removed,. . but belt belts are particularly prone to breakage and even loss, and all of them usually have to be replaced every time. Known locking means for molded plastic pieces 30 are also susceptible to breakage, in particular when the insulating pieces are removed. The greatest problem, however, is that such locking means of the molded parts ... - cause the locking means to open during use. This opening of the locking device causes the entire insulating shape! song detachment.

Because of the need to keep maintenance or revision operations in various industries as short as possible in order to minimize damage to the production itself, the removal and securing or re-insulating of known insulators has proven to be very cumbersome and expensive.

Brief Description of the Invention

It is therefore an object of the present invention to substantially improve the insulation of pipelines and, in particular, to facilitate the temporary removal of insulation, for example during maintenance work.

This object is achieved in that the insulating body according to the present invention has the features defined in the claims. More specifically, the device according to the invention is essentially characterized by what is stated in the characterizing part of claim 1.

In the context of the present invention, the term "piping" 15 generally refers to various pipelines or pipelines for conducting both gases and liquids. Although this specification mainly describes the utilization of the invention in connection with such piping systems, this does not exclude, for example, the cladding of various machine parts or complete devices with the insulating modules according to the invention.

Preferred embodiments of the invention are claimed in the dependent claims.

A variety of insulation modules are achieved with the piping according to the invention. . : Benefits. When the insulation provided by the insulation modules according to the invention is no, it is necessary to both assemble and disassemble the maintenance operations carried out, for example, in various industries, in the shortest possible time, thereby causing minimal damage to the production itself. At the same time, both accelerated construction work and accelerated maintenance work bring significant economic benefits to the customer using the insulation.

An insulating module such as the present one forms an easy-to-handle, · 30, assembly from which no essential parts required in the assembly step are lost. Because the insulation can also be divided into the most suitable insulation modules for the particular application, it is easy to handle the insulation pieces, which substantially reduces damage to the insulation pieces.

Due to their simple locking arrangement, the insulation modules 35 according to the invention can be easily and firmly connected to each other. Because the locking system can be opened and closed with a simple hand-operated tool, power tools are avoided. This greatly simplifies the handling of insulators, particularly in flammable areas where tools must otherwise be protected against sparking.

Due to the simple construction of the insulating module according to the invention, their handling does not require any special workers either, but maintenance and other operations can be outsourced to industrial service personnel. This avoids the use of expensive specialist dealership services and can better plan maintenance work to suit your own work schedule. Since no structural members protrude from the outer surface of the insulating module according to the invention, the insulating module is not as susceptible to damage as known solutions. When the locking means are fitted to the edges of the insulation modules as an integral part of the insulation module, they remain much more intact during maintenance and similar work when the insulation of the piping has to be dismantled. The locking means forming an integral part of the insulation module also prevents their loss during such maintenance and similar work.

Since the insulating modules according to the invention can be aligned with each other by the tongue-and-groove structure provided at their edges, a completely uniform and even surface structure is also obtained. This avoids the disadvantages of * known components of the protruding components, such as sticking them to a passing worker's clothing, which may result in their opening. A flat exterior also allows for multiple: insulating module overlay if larger * *: ·; 25 pia layers of insulation. By installing successive insulating modules in a partially overlapping position, the thermal expansion of the object to be insulated can also be easily taken into account in pipelines with thermal expansion. . especially great.

; The locking module used in the insulation module of the piping according to the invention; · '30 also allows for changes in the insulation layer diameter with simple spacers.

·: In long continuous pipelines, insulation modules can be connected * at the manufacturing stage by pairs of joints, such as hinges, which are fitted to opposite side edges. In this way, the installation of insulation modules can be significantly accelerated.

110814 By arranging the locking means connecting the insulation modules to one another, for example by providing eccentric clamping means, the isolation modules are prevented from being separated from each other by, for example, vibration stressing the piping.

5 In general, similar standardized pipelines are used as pipelines in different industries, with the material varying due to different needs or circumstances. By studying these similarities, it is also possible with the present invention to find insulation solutions for insulating modules suitable for different piping systems, which can also be standardized and thus manufactured in larger series. This will allow the production of a standard product currently used on the market as technical insulation. Thus, the insulation modules can be manufactured in compatible sets of dimensions, whereby the fit of the insulation modules to the pipe dimensions can be verified. In this case, the insulating layer of the insulation module, due to its sandwich structure, also makes it possible to make exactly the right kind of application for different application areas by providing it with different types of insulation as desired.

The present piping insulation system and a preferred embodiment of the insulation module used therein are described below with reference to the above figures. Herein, the insulation system comprises reference numerals corresponding to the reference numerals used in this specification.

Thus, the insulation system preferably comprises a sandwich insulating module surrounding the piping to be protected. Such an insulating module comprises substantially parallel surface plates which form the insulating module with its outer surface 1 and inner surface 2.

The insulation module is adaptable in shape to the insulated piping 4. Accordingly, Figs. 1 and 2 show an insulating module having an inner and a float; the fronts 1 and 2 are substantially cylindrical in shape with conventional circular piping. Although the figures show only the insulation modules associated with the circular piping 30, the insulation module may equally be fitted around, for example, * ·, a rectangular or other polygonal piping or associated device or part. Thus, the curves or shapes of the inner and outer surfaces of the insulation module can be adapted to any curvature or shape of the piping. In addition to the insulating modules of longitudinal symmetry according to Figs. 1 and 2, the insulating module also comprises very diverse modules. Such may be, for example, tapered, expandable or branched modules according to Figure 5.

Such insulation modules of the invention can be interconnected by locking means. Such locking means are arranged on the connecting surfaces 5 and 6, i.e. the side and end edges, connecting the outer surface 1 and the inner surface 2 in the insulation module 5. The locking means is disposed in the insulating space 7 between the outer surface and the inner surface so that at least in its open position it is substantially arranged inside the insulating space. In order to facilitate the insertion of the insulating modules, size or half points can also be advantageously provided at the edges. Such a tongue-and-groove structure ensures precise adjoining of the adjacent insulation modules. If necessary, seals and / or overlaps of the type known per se can be further provided at the edges to confirm splash protection, dust tightness or even gas tightness of the insulation.

A preferred embodiment of the locking means connecting the insulation modules to each other comprises gripping members 8 and fastening members 9 on opposite connecting surfaces of adjacent and / or opposite insulation modules. Such a gripping member has a gripping means 11 movable with respect to the body 10 therein and protruding out of the connecting surface, the gripping means being advantageously controllable by the fastening means 20 of the opposite insulating module, whereby the gripping means protrudes into The gripping means and the clamping stop are then adapted to: · provide mechanical locking to each other.

The gripping means is then arranged ·. to rotate about a axis of rotation perpendicular to its longitudinal axis. This gripping means may be adapted to control a separate gripping member. . tool 13, for example a crank. This crank is then fitted; preferably a locking opening 14 on the outer surface 1 of the insulating module, from which it engages a crank hole 15 in the gripping means and which engages the axis of rotation. The rotational movement of the palm thereby guides the gripping means to approach or move away from it. The gripping means may also be adapted to control an eccentric pivoting wheel 16 having a palm-receiving crank hole as shown in Figure 4.

In its resting position, the gripping means 11 is pivoted into a cavity 17 of the gripping member 8 by guiding the gripping means with a tool 13 fitted thereto, the gripping means pivots substantially perpendicular to the connection surface 5 or 6. When the insulating modules are mounted in an opposed position 5 against the gripping member 8 and the securing member 9, during the pivoting movement, the engaging means engages in the securing member on the connecting surface of the opposing insulating module. The fastening member thus comprises a cavity opening towards the joint surface of the insulating module having a fastening stop 12 perpendicular to the direction of movement of the engaging means. When the engaging means reaches this fastening engagement, the hooked end of the engaging member engages with

In order to provide a strong connection, the gripping means 11 comprises an eccentric pivoting disc 16 fitted to the body 10 of the abovementioned gripping member 8 which, via the control movement of the tool 13, moves the gripping means substantially parallel to its aperture 17 Thus, the hooked end of the engaging means will partially encircle the retaining clip 12, preventing incorrect connection of the joint.

By co-operating with the gripping means 11 and the fastening stop 12, a strong connection is provided between the insulation modules, without any separate constructions interfering with the use of the insulation module protruding from the outer surface 2 of the module.

The locking means are provided on the connection surfaces of the insulation modules in an appropriate amount, however, at least one at each end edge 1 · 6 of the insulation module and at least one at each side edge 5 of the insulation module.

When required by the insulating module, splash protection or other structural sealing means may be provided in the locking aperture of the engaging member by means of a spinning seal 18, as shown in Figures 6 and 7. Such. the pivoting means is in continuous contact with the crank hole 15 in the engaging means 11 and which engages the rotary axis. The pivoting means then closes the locking opening 14 30, whereby the engaging means is guided by a separate tool 13,

Another embodiment of the insulating module preferably comprises two insulating modules consisting of articulated pieces. However, when such an insulating module 35 is used, locking means such as those described above are required in addition to each end edge 6 of the insulating module only on its other side edge 5.

The insulation module according to the present insulation system operates as follows. Conventionally, two structurally symmetrical insulating modules 5 are arranged opposite each other around the piping 4 with the side edges 5 facing each other with the engaging means 11 in a resting position. When the insulating modules are in position, the connecting surfaces are turned against the engaging means by a tool 13, which is fitted to the locking opening 14 on the outer surface 1 of the insulating module. The gripping means rotates by engaging the retaining means 12 of the fastening means 10 in the opposing insulating module, thereby locking the insulating modules together. The following pairs of insulation modules are similarly placed around the pipeline, after which the modules attached to each other are dissolved in a pair of insulation modules already installed in the pipeline. In this way, the locking means at the end edges 6 of the insulation modules are guided against each other and the pairs of insulation modules can also be connected to one another in the longitudinal direction of the piping. This longitudinal locking is better than usual to prevent the insulating modules from leaking too often, especially when insulating vertical piping. This is continued until the desired piping section is isolated.

Insulation modules are easy to manufacture of the desired design to encircle both piping 4 of variable diameter as well as branched piping or equipment or filters in connection with the piping. The inner diameter surrounded by the insulation modules can also be varied by fitting one or more interconnecting members 19 between pairs of insulation modules as shown in Figure 5. Such a connector is attached to the insulation modules using locking devices similar to those used to • connect the insulation modules. The connecting piece may be a piece tailored to a specific insulating object, but it may also comprise a so-called gauge replacement piece. With such a replacement piece. . insulating modules made of a series of openings are connectable; / to each other.

Such connectors may also be used to connect an insulating module such as the present one to an existing pipeline 4; · But for insulation or fixed insulation around piping.

In this case, the connecting piece 19 is joined, for example, by riveting to a dielectric of conventional construction, after which the insulating module of the present embodiment can be connected to this connecting piece by means of locking means at the end edges 10 1108146. This provides an insulator that is uniform throughout the pipeline and is substantially stationary throughout its travel.

The inner diameter enclosed by the insulation modules can also be varied by fitting the pairs of insulation modules in an overlapping position as shown in Figure 2.

Contrary to known solutions, this is possible because when using the locking device according to the invention no protrusions are formed on the outer surface 1 of the insulating module. Thus, the insulating modules in the overlapping position may also slip relative to one another, whereby such a structure can advantageously be used to compensate for large thermal expansions by installing an insulating module of larger size on the insulating module line as a sliding insulator. Most preferably, such a slip insulator is installed in connection with the flange connection shown in the figure.

The insulation surrounding the piping 4 may be divided into two or more insulation modules based on the requirements of the object to be insulated. 15 In this way, even in confined spaces, easy-to-install and dismantle insulation is achieved, minimizing the time spent on insulation work. By dividing the insulator into several smaller modules, the transport and storage of the modules is also substantially facilitated. However, the locking means used allow fast and precise connection of the insulation modules to each other.

It is to be understood that the foregoing description and the accompanying figures are ν ': only intended to illustrate the present invention. The invention is not: thus limited to the embodiment described or claimed, many will be apparent to those skilled in the art. various variations and modifications of the invention which are possible within the scope of the inventive idea defined in the appended claims.
