Pipe insulation jacket made from a malleable,
elastic plastic

The innovation concerns a pipe insulation jacket made of a malleable,
elastic plastic with a web-like spring tongue and a
Groove on different sides of a longitudinal slot and with
Support webs that stand up on the pipe wall. . . \

Insulations from: Foam are already known to insulate pipes against heat emission, Ii poor on,! Activity and / or corrosion effects, in which an additional outer cover layer ■ to hold the foam and to close the insulation; coat is required. There are also ear insulation jackets in one! malleable, elastic plastic of the type mentioned: become known that in the form of a double or multiple ring jacket! are designed with numerous chambers running in the axial direction. Such a double or multiple ring coat! shows. ; Due to its multi-sided structure, a considerable rigidity \ and dimensional stability, so that it is difficult to create such a
Deforming manner, so that the same over -the Rohr.gezogen _are: Rohrisoliermantel during installation on a pipe in sufficient can. It is with one of these. Double rain-lringman-iel with axial Chamber \ chambers very expensive and therefore hardly possible in practice that: fill chambers with an insulating, which in some cases' ■■

to improve the insulation effect is desirable. In the end it is extremely expensive to produce such double and multiple ring jackets for a whole range of a series of γοη tubes "to have ready ♦

The task of the hiring is such a formation of a pipe insulation jacket, that it can be easily and effortlessly drawn over a drill hole can be and still sits dimensionally stable on the same * In addition, the chambers running in the axial direction should be a multi-shell insulation easily with the required Insulating material can be filled out.

According to the innovation, this is achieved by the fact that with their clear inside dimension is the outside diameter of a pipe in a 3} ypen row corresponding support webs sit on a shell-shaped outer jacket, which in the area of the longitudinal slot in the radial direction is reinforced to accommodate the spring-like closure, and that in each case the outer jacket outer diameter of a larger pipe same series of types.

Tube-The insulating jacket according to the innovation has only one single-shell outer jacket so that it can be easily bent during assembly and pulled over the pipe in question, After putting on the outer jacket, the Mngs slit the same without difficulty by means of the leather clasp provided to lock. The pipe insulation jackets of a row of lyps; ©., are dimensioned after firing so that the difference between Inside and outside diameter of a Rohrisoliermänteis each the Gradation of two pipe diameters of the series is the same.

As a result, every Rolaris. for the inside diameter the same pipe as the insulating jacket between the support webs to be used. "If you have a multi-layer insulation if desired, a second pipe insulation jacket of the following size can be used be pulled over the first pipe insulating jacket, wherein the desired number of pipe insulation jackets. corresponds to the required degree of insulation. With every insulating jacket Such a multi-layer insulation can be the longitudinal chambers When assembling, fill it lightly with an insulating material.

Further details of the innovation can be found in the following Description of some preferred embodiments in connection with the accompanying drawing »It represent; ;. . . Figure 1 is an end view of a .Rohrisoliermantels according to

4-6 different versions of the spring-like closure in the area of the longitudinal slit.

FIG. 1 initially shows a pipe 1 that is to be insulated. The pipe insulating jacket 2 according to the innovation consists of. a single-shell outer jacket 3, which has a longitudinal seat 4 and from which support webs 5 ~ ~ protrude radially inward. In the area of the longitudinal slot, the outer jacket 3 ... is reinforced in the radial direction, in particular the support web; 5 'is widened and has a built-in locking groove 6. A web-like spring tongue 7 is attached to the opposite edge of the longitudinal slot The inner profile of the longitudinal groove 6 is the same . ""_'--- -. . ^; ■■ - '. " ■" ■ /.

The pipe insulating jacket 2 after the inflation can be in any length can be made. As a plastic material is suitable in particular a polyamide, a polyethylene or another elastic plastic material that can be formed by extrusion. The pipe insulation jacket can each "au $ der Construction site can be viewed to the desired length. Since the outer jacket 3 is a single layer, the pipe insulating jacket can be seen After the innovation, bend it up easily and pull it over the pipe 1. Then the spring-like closure 6, 7 is pushed into one another or plugged into each other, with which the insulating jacket is finished. In order to is the pipe 1 against the effects of heat or cold, as well as against the effects of moisture and other corrosion influences protected. Palis is required, the axial longitudinal chambers 8 fill between the support webs 5 with an insulating material, each in front of the sheathing of a pipe 1 in the longitudinal chambers is inserted. These longitudinal chambers directly adjoining the pipe 1 are extraordinary for effective insulation Cheap.

Figure 2 shows a modified embodiment of the pipe insulating jacket according to the innovation, where the support webs protruding from the outer jacket 3 have a triangular profile. angular support web. Together with the pipe 1 then result; Longitudinal chambers 8 with an approximately triangular profile. Between \ respective adjacent walls 9 are also longitudinal chambers 8 'i found. Also this Rohrisoliermantel after Pigur 2 \ can be when assembling a pipe bend easily because the outer casing 3! in the respective attachment points 10 of the walls 9 of a Yerbiegungj

offers only a comparatively low resistance. In this Pall, the lock is designed as a radial lock, a spring tongue 7 'attached in the radial direction engaging in a corresponding groove 6'. It is also important that the respective groove 6 ″ or 6 ^{f is located} within a reinforced support web, so that the pressure pressure can be absorbed by this support web resting on the wall of the tube 1 without the possibility of deformation or even damage to the ■ In the embodiment according to FIG. 2, too, the longitudinal chambers can be filled with an insulating material.

Figure 5 shows a multi-layer insulation with pipe insulation jackets according to the innovation, which belong to a series. Pipes, for example water pipes or the like, are available according to a type set with graduated diameter knives. The innovation now proposes grading the pipe insulation jackets according to a corresponding row, with the inside and outside diameter of each pipe insulation jacket in this row being the same as the difference between two pipes within the row of pipes. This means that you can use any pipe insulating jacket as an insulating jacket for the associated pipe. If, however, a multilayer insulation is required to improve the insulation effect, the pipe insulation jackets, which are graded according to a series of types, can be placed around one another, as shown in FIG. 2 for the pipe insulation jackets 2, 2 ¹ , 2 ^tT . These pipe insulation jackets 2, 2 'and 2 ^I! are in each case successive sizes of a type series, which therefore fit one another exactly according to the above dimensioning. With this arrangement in particular, it is important that the longitudinal chambers of each pipe insulation

mantels "during assembly directly to insert an insulating material are accessible. In addition, support; each with the support webs the locking groove in the area of the longitudinal slot on the one below Located from the pipe insulating jacket, so that the closures can be nested without much effort., because. the "relevant support webs find a secure support.
