Abstract

A wrapping bandage for use in sealing leaking spots in piping and for pipe insulation consists of a thermoplastic material which is automatically restored after it has been stretched. Suitable materials are PVC contg. a plasticizer or rigid PVC. The former need not be wrapped very tightly nor does it require the applicn. of heat. Rigid PVC is suitable for higher internal and external pressures but requires the applicn. of heat above the stretch temp.

Description

Verfahren zur Abdichtung von Rohr-Process for sealing pipe

Leckstellen sowie zur Rohr-Isolierung mittels Wickelbinde.Leakage points as well as pipe insulation using a wrap.

Beschreibung: Die bekannten Wickelbinden zum Abdichten von Rohr-Leckstellen sowie zur Rohr-Isolierung weisen den großen Nachteil auf, daß sie ebenso unhandlich bei der Anbringung wie teuer vom Produkt her sind und sich damit kostenungünstig stellen. Ein weiterer Nachteil ist darin zu sehen, daß sie auftretende Innendrücke nur bedingt abzufangen vermögen.Description: The well-known bandages for sealing pipe leaks as well as pipe insulation have the major disadvantage that they are just as unwieldy how expensive the product is when it comes to attaching it, and thus how inexpensive it is place. Another disadvantage is that there are internal pressures are only able to intercept them to a limited extent.

Die Erfindung hat es sich nun zur Aufgabe gemacht, diese Nachteile zu beseitigen und sieht folgende Lösungen vor: Die erfinderisch neue Wickelbinde besteht aus einem thermopla stischen Material, das sich nach Reckung wieder zurückstellt.The invention has now set itself the task of addressing these disadvantages to eliminate and provides the following solutions: The inventive new wrap-around bandage consists of a thermoplastic material that resets itself after stretching.

Als besonders geeignet erweist sich das PVC, welches in weichmacherhaltiger Form wie auch als Hart-PVC zum Ansatz kommen kann.PVC, which contains plasticizers, has proven to be particularly suitable Form as well as hard PVC can be used.

Eine Wickelbinde aus weichmacherhaltigem PVC kann kalt gereckt und als Rolle gewickelt - zum Schutz gegen vorzeitigen Rückschrumpf - eingesetzt werden. Die Rückstellgeschwindigkeit eines solchen kaltgereckten PVC-Streifens ist direkt von der Menge des seines Weichmachers abhängig, die Rückstellung selbst erfolgt dabei ohne jede Wärmezufuhr. Von der Rückstellgeschwindigkeit abhängig ist die "offene ickelzeit, das ist die Zeit, die alsdann beim Ansatz der Binde zur Umwicklung des Rohres vorgegeben ist: Je größer der prozentuale Anteil an Weichmacher ist, umso schneller vollzieht sich die Rückstellung und umso kleiner stellt sich die offene Wickelzeit.A wrap made from plasticized PVC can be cold-stretched and wound as a roll - to protect against premature shrinkage - can be used. The recovery speed of such a cold stretched PVC strip is straightforward Depending on the amount of its plasticizer, the provision itself takes place without any heat supply. The "open" depends on the reset speed ickelzeit, that is the time it takes when the bandage is set to wrap around the Rohres is predefined: the greater the percentage of plasticizer, the greater The reset takes place faster and the smaller the open one Wrapping time.

Der große Vorteil dieser Art von Wickelbinden ist darin zu sehen, daß ein sonst übliches festes Anziehen oder gar Recken der Binde beim umwickeln des Rohres entfällt, ebenso bedarf es keiner Aufwärmung der wicklung, Eine lose Umwicklung genügt, da der gleichmäßige Rückschrumpf auf ganzer Länge erfolgt und ein absolut festes und dichtes Aufsitzen der Binde garantiert.The great advantage of this type of bandage can be seen in the fact that that an otherwise usual tightening or even stretching of the bandage when wrapping of the tube is omitted, there is also no need to warm up the winding, one loose Wrapping is sufficient, since the even shrinkback takes place over the entire length and an absolutely firm and tight fit of the bandage is guaranteed.

In Sonderfällen kann es zweckmäßig sein, ein warm gerecktes, weichmacherhaltiges PVC-Band einzusetzen. Je nach Ansatz kann das PVC-Band dabei unter- oder über dem Plastifizierungspunkt gereckt sein.In special cases it can be useful to use a warm stretched, plasticizer-containing Use PVC tape. Depending on the approach, the PVC tape can be above or below the Be stretched plasticization point.

Eine extrem hohe Druckfestigkeit gegen Innen- und Aussendrücke wird dadurch erreicht, daß ein gerecktes Hart-P\JC-Band, eingesetzt wird. Dessen Rückschrumpf kann nach der Umwicklung nur durch Erwärmung über die Recktemperatur ausgelöst werden.Extremely high compressive strength against internal and external pressures achieved in that a stretched Hart-P \ JC tape is used. Its shrinkage can only be triggered by heating above the stretching temperature after wrapping.

Als sehr vorteilhaft erweist sich zudem die Kombination einer weichmacherhaltigen mit einer Hartbinde, da die erstere eine vorzügliche Abdichtung und die zweite eine große Druckfestig keit erbringt.The combination of a plasticizer-containing one also proves to be very advantageous with a hard bandage, since the former is an excellent seal and the latter is an excellent seal provides great compressive strength.

Diese Kombination kann zweierlei Gesicht haben: Zum einen wird das Rohr zunächst mit einer Weich-Binde und danach mit der aus Hart-PVC umwickelt, zum anderen kann die Binde selbst aus einer Kaschierung beider #yp#n-bestehen. Auslösung des Riickschsumpfes erfolgt auch hierdurch Erwärmung Die Breite und Materialstärke aller Wickelbinden ist auf ihren Ansatz zugeschnitten, ebenso wird deren Farbgebung vom Einsatz bestimmt. This combination can have two faces: On the one hand, it will Pipe wrapped first with a soft bandage and then with the rigid PVC, for For others, the bandage itself can consist of a lamination of both # yp # n -s. Tripping the back sump is also heated as a result of this. The width and material thickness all wraps are tailored to your neckline, as is their color determined by the use.

Von den Material- wie Arbeitskosten her zeigen sich die aufgezeigten Verfahren als sehr günstig und sichern bei Ansatz des jeweils -zweckdienlichen roduktes eine sichere Abdichtung des Rohres. In terms of material and labor costs, the ones shown are evident Process as very cheap and secure when using the appropriate product a secure sealing of the pipe.
