Pipe insulator

The invention relates to a pipe insulating body made of strip-shaped ^ synthetic, felt-like material covered with thin plastic material.

Such material is usually wrapped around conduit pipes with the plastic film facing outwards, around them to insulate with respect to heat, sound and / or corrosion. The plastic film located on the outside serves to protect against dangerous Corrosion influences such as condensation water, cement additives, Plaster of paris, chemical influences and electrolytic reactions to ensure effective protection · The plastic coating also acts as a vapor barrier.

However, wrapping the pipes to be insulated is a laborious precaution, especially with longer pipelines. It is particularly difficult to wrap pipes laid very close to the wall, as the strip-shaped material has to be constantly forced between the thin gap between the pipe and the wall. Another disadvantage of the wound insulating strips is that despite the plastic film coating there is a risk of moisture entering the numerous seam surfaces, especially because careful wrapping by a skilled person cannot always be expected.

The aim of the invention is now to create a pipe insulating body of the type mentioned, which can be applied quickly and easily to the pipes to be insulated with simple and economical production can and still guarantees an excellent seal against corrosive influences.

To solve this problem, the invention provides that the plastic material is a flexurally elastic sheet material, which has essentially the shape of a cylinder having a longitudinally extending cutout. The cutout is preferably so wide that it can be pushed over the pipe at least after elastic expansion is.

The sheet material is expediently on the outside and the felt-like Material inside.

While the sheet material is preferably about 0.5 mi thick, the felt-like material can be, for example, 3 to 6 mm thick.

The basic idea of the invention is thus to be seen in the fact that the strip, which consists of flexible sheet material and, for example, felt-like material glued to it, is given a shape from the outset which largely approximates the pipe orsa suiiuü, but still allows the entire structure to be easily applied to the Pipes are guaranteed even if they are already welded at their ends, so that application from the end face of the pipes is no longer possible. A suitable choice of the sheet material is particularly important here, which must be so resiliently elastic that it admittedly assumes the desired shape if no external stresses are effective, but that by applying a slight external stress it easily becomes a closed tube is malleable. In addition, it should be able to be pushed easily over the pipes by expanding.

The sheet material should therefore be chosen so that the longer ones Overlap the side edges under the outer lining. Due to the tension, the sheet material and the felt-like material in the overlap area are so close together that that e.g. when applying cement or plaster of paris, these substances are prevented from penetrating the interior of the insulation will. This is achieved wildly, although only an external tension is applied and no gluing is provided.

A good tightness is achieved if the overlap area is 10 to 20 % of the circumference of the tubular insulating body.

On the sheet material brackets are preferably arranged at predetermined intervals, which the sheet material in the Press the overlap area together. This embodiment is particularly economical to use because in the case of longer insulation only at certain distances

Plastic applied clamps that can be manufactured very cheaply that ensure good insulation and tightness.

The pipe insulating body according to the invention is particularly suitable for longer pipelines without major curvatures. Greater curvatures are expediently bridged using the conventional winding method.

The invention is described below, for example, with reference to the drawing; in this shows:

1 shows a cross section of a pipe insulating body according to the invention in the de-energized state and

2 shows the same body after applying an external tension by means of a clamp.

According to the drawing, there is a felt-like one about 3 "to 6 mm thick Material 14 is surrounded by a sheet of material "Ι which is glued, for example can be. According to the invention, the sheet material 11 has such an elastic flexural rigidity that without the If external forces are present, the shape shown in FIG. 1 is maintained. The sheet material 11 thus supports the felt-like Material 14 and gives it the shape shown in FIG. 1.

The sheet material 11 has a substantially cylindrical shape, but with a lengthwise direction of the cylinder extending cutout 12 is left. The purpose of this cutout is to slide the insulation onto a pipe possibly to be applied with widening.

After the pipe insulating body has been applied to the pipe 13, the side edges 15 »16 according to Fig. 2 are pushed over one another by applying an external tension, e.g. by hand, so that an overlap area 17 is formed. This final

The shape of the ßohrisolierkörpers is created by putting on a only schematically shown clamp 18 fixed, which the two material layers in the overlap area 17 η presses differently. This not only provides good thermal insulation also achieved at the seam, but also excellent tightness.

In all cases , the seam ″ at 15 in FIG. 2 can also be completely sealed off from the outside by an adhesive strip, although this is generally not necessary.
