Description
Die Erfindung richtet sich auf eine Vorrichtung zum Schutz der freien Enden von Metallrohren bei der Beschichtung mit Kunststoff, wie Polyethylen oder dergleichen. Eine Abdeckeinrichtung für Lackierarbeiten auch an Rohrenden zeigt das
Da Rohre nicht in beliebigen Längen herstellbar sind werden einzelne Rohrschüsse erzeugt, die dann im Gebrauchsfall vor Ort miteinander verbunden werden.Since pipes can not be produced in any length individual pipe sections are generated, which are then connected in use on site together.
Zum Korrosionsschutz ist es dabei bekannt, die Außen- und/oder Innenoberfläche der entsprechenden Rohrschüsse mit Kunststoff zu beschichten, z. B. mittels eines Polyethylenüberzuges, hier können auch andere Beschichtungen vorgenommen werden, beispielsweise thermoplastisch aushärtende Epoxyharzschichten oder dreilagige Polyolefinbeschichtungen oder dergleichen.For corrosion protection, it is known to coat the outer and / or inner surface of the corresponding pipe sections with plastic, z. Example by means of a polyethylene coating, other coatings can be made here, for example, thermosetting epoxy resin or three-layer polyolefin or the like.
Um die spätere Stoßkante, an der die Rohrschüsse durch Schweißtechnik miteinander verbunden werden, von derartigen Beschichtungen freizuhalten, werden die Rohrenden abgeklebt, wobei die entsprechenden Klebematerialien später wieder entfernt werden, wenn die jeweiligen Rohrenden blankgelegt werden. Ist die Schweißnaht auch vorhanden, wird dann das fehlende Stück Beschichtung auf beiden aneinanderstoßenden Rohrenden durch eine vor Ort aufzubringende Beschichtung korrosionsfest ausgerüstet.In order to keep the later abutting edge, at which the pipe sections are connected to one another by welding technology, from such coatings, the pipe ends are masked off, with the corresponding adhesive materials being removed later when the respective pipe ends are laid bare. If the weld also exists, then the missing piece of coating on both abutting pipe ends is equipped corrosion resistant by a locally applied coating.
Ein Problem beim Abkleben der Rohrenden besteht darin, dass nicht immer gewährleistet werden kann, dass sämtliche Klebstoffe, die beim Abkleben auf die Rohroberflächen aufgebracht werden, wieder vollständig entfernt werden, so dass es zu Problemen bei der Schweißnahtausbildung kommen kann.A problem with masking the pipe ends is that it can not always be guaranteed that all adhesives that are applied to the pipe surfaces during the masking process are completely removed again, which can lead to problems in the formation of welds.
Hier setzt die Erfindung ein, deren Aufgabe darin besteht, einen Rohrschutz der Metallrohrenden zu gewährleisten bei der Beschichtung mit Kunststoffmaterialien, der leicht zu entfernen ist und das Stoßende der Rohre sicher von Klebstoffpartikeln freihält.This is where the invention comes in, whose mission is to ensure pipe protection of the metal pipe ends in the coating with plastic materials, which is easy to remove and safely keeps the butt end of the pipes of adhesive particles.
Mit einer Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, dass
- – dass sie als auf die von der Kunststoffbeschichtung freizuhaltenden Rohrenden aufzubringendes Klebeband ausgebildet ist,
- – dass die Breite des Klebebandes größer ist als die Breite des von der Kunststoffbeschichtung freizuhaltendem Rohrendes und
- – dass der über das Rohrende hinausstehende Bereich etwa die halbe Breite des Klebebandes beträgt und klebstofffrei ausgebildet ist.
- That it is designed as an adhesive tape to be applied to the pipe ends to be kept free of the plastic coating,
- - That the width of the adhesive tape is greater than the width of the freizuhaltendem from the plastic coating pipe end and
- - That beyond the pipe end projecting region is about half the width of the adhesive tape and is formed adhesive-free.
Bei dieser Gestaltung ist zum Einen möglich, das Schutzband sicher auf das freizuhaltende Rohrende aufzubringen, gleichzeitig bewirkt der klebstofffreie Bereich des Schutzrandes, dass in die Stirnseiten des Rohres keine Klebstoffpartikel eingebracht werden.With this design, on the one hand, it is possible to securely apply the protective tape to the pipe end to be kept clear, at the same time the adhesive-free region of the protective edge causes no adhesive particles to be introduced into the end faces of the pipe.
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Embodiments of the invention will become apparent from the dependent claims.
Um das Applizieren des Klebstoffbandes zu erleichtern kann vorgesehen sein, dass der klebstoffbeschichtete Bandstreifen und/oder der klebstofffreie Bandstreifen optisch unterschiedlich ausgestaltet sind, etwa durch unterschiedliche Färbung des jeweiligen Trägerbandes.In order to facilitate the application of the adhesive tape, it may be provided that the adhesive-coated tape strip and / or the adhesive-free tape strip are optically configured differently, for example by different coloring of the respective carrier tape.
Nach der Erfindung kann aber auch vorgesehen sein, dass der Übergang vom klebstoffbeschichteten Bereich zum klebstofffreien Bereich auf der Bandaußenseite optisch markiert ist, etwa durch einen Streifenaufdruck oder dergleichen.According to the invention, however, it can also be provided that the transition from the adhesive-coated area to the adhesive-free area on the outside of the strip is optically marked, for example by a strip imprint or the like.
