The innovation relates to a pipe coating in the form of a hose made of insulating material or a sleeve, which is used to protect pipes against Temperature influences of the environment is bestismat »

The previously known made of insulating material, over the pipe to be protected su sohiebenden hoses or sleeves have the disadvantage that aie are completely closed on the circumference and therefore not subsequently without dismantling at least one of the au insulating tube can be pushed over this. However, such disassembly is common in many cases not possible or very time-consuming and cumbersome. In addition, the insulating effect of the laoli hoses or Iaolierßuffen often unsatisfactory lat.

The firing avoids the existing Kaoh parts. It differs from ά & χι previously known directions above all in that it is one on one side

Hoses on that too. insulating pipe are underneath. Nothing stands in the way of the innovation, including taking place two, three or more such foam tubes or -Slide the cuffs in or on top of each other.

The acidification is also particularly suitable for subsequent Reinforcing an insulation of the same or that has already been applied to the pipe or pipes from the start of a different kind, since one has ea in hand, one or other foam tubes subsequently over this insulation or foam sleeves by adding the slotted foam tubes or sleeves spreads and pushes from the side over the existing insulation.

Details of the innovation result from the following description of the one shown in the drawing Working examples.

mainly by means of a glowing wire lengthways slotted, over the pipe to be insulated to be pushed foam hose or a foam sleeve "preferably based on polyester resins and isocyanates. In that the hose is slit at one point in the longitudinal direction iat, it can be easily spread over $ of the tube be pushed, so also afterwards over such pipes, which are already connected with their ends feet without that one end or the other needs to be solved. The one made of foam © insulating tube or the Isoliermuffe has a very good insulating effect and is also largely elastic, so that it can easily adapt to unevenness and curvatures.

The one in the foam tube or the foam sleeve The longitudinal slot located is renewed according to the application of the hose to the to be protected Tube glued.

In a further embodiment of the invention, several foam tubes or sleeves can be placed inside or on top of each other be pushed. One of the foam tubes is then applied and the other over it pushed by spreading it apart. Both hoses are then rotated to each other so that their longitudinal slots are offset from one another. In this case, there is no need to glue the slits through the each full area of the preceding or following hose are covered, so that at these points. Temperature influences of the environment on the or the

S ¹ Ig. 5 shows a cross section through Fig * 4 in the direction BC.

When executing according to Pig. 1 is the foam tube provided with a radial longitudinal slot 2. It can thereby be spread in the radial direction and over that in each case insulating pipe to be pushed. In the pig. 3 are several such tubes 4 shown, the two heat sinks 3 connect with each other. Above these pipes are exposed fabric hoses or sleeves 1 pushed, for example in the direction of arrow a. The slot 2 becomes advantageous glued after sliding it on.

Instead of one, several foam tubes can be used or sleeves are pushed over a pipe 4. For example, two foam tubes or sleeves 5, 6 according to Fig. 2 can be pushed over or into one another. It will first the foam tube 5 spread and then over the tube 4 in question is pressed. Then the foam tube 6 is spread and over the foam tube pressed. The two foam tubes 5 »6 so arranged to one another that their radial longitudinal slots 2 are offset from one another. You can both - like shown in Fig. 2 - in the same as - as not shown - lie in different radial planes.

If the insulation is to be attached to a location where there is a valve or a pipe branch » then the foam tube or the foam Provide a cut-out at this point.
