Rohr aus KunststoffPlastic tube

Die Erfindung betrifft ein Rohr, insbesondere ein Rohr aus Kunststoff für die Versorgung von HausanschlUssen oder anderen Rohrleitungen in Gebäuden und in der Industrie. Rohre aus Kunststoff sind leichter zu verlegen als Rohre aus Metall, sind korrosionsfest und neigen wegen ihrer glatten Oberflächen zum Ansammeln von geringeren Mengen von Schmutz und anderen Stoffen als ihre Gegenstücke aus Metall und erleiden aufgrund der nachgiebigen Natur des Kunststoffs selbst wahrscheinlich eine geringere dauernde Beschädigung.The invention relates to a pipe, in particular a pipe made of plastic for the supply of house connections or others Pipelines in buildings and in industry. Plastic pipes are easier to lay than metal pipes, are corrosion-resistant and, because of their smooth surfaces, tend to collect small amounts of dirt and others Fabrics than their metal counterparts and are likely to suffer due to the compliant nature of the plastic itself less permanent damage.

Das Verbinden von Rohren aus Kunststoff erfolgt für gewöhnlich durch Klebstoff oder herkömmliche Gewindeanschlüsse.The joining of plastic pipes is usually done with glue or conventional threaded connections.

Unglücklicherweise ergibt die glatte äußere Oberfläche von Rohren aus Kunststoff im allgemeinen einige Schwierigkeiten bei der Verlegung, da sie den Monteuren das Ergreifen des Rohrs in der Weise erschwert, die zum Festziehen einer Rohrverschraubung unter Verwendung eines Rohr- oder Drehmomentschlüssels erforderlich ist. Insbesondere verformt die Ausübung von Druck auf das Rohr dieses wahrscheinlich. Jedoch ergibt die biegsame Natur vereinigt mit der glatten Oberfläche lediglich ein Drehen des Rohrs unt«.r dem auf die Schraubverbindung ausgeübten Drehmoment.Unfortunately, the smooth outer surface of plastic pipes generally creates some difficulties in installation, since it makes it difficult for installers to grasp the pipe in the manner required to tighten a pipe fitting using a pipe wrench or torque wrench is required. In particular, the exertion of pressure on the pipe deforms it probably. However, the flexible nature combined with the smooth surface only results in a turning of the tube underneath torque exerted on the screw connection.

Die Verwendung von Handschuhen, ein Aufrauhen oder andere ähnliche Verfahren zum überwinden und Erhöhen der Reibung zwischen einem Greifer und dem Rohr kann unterstützend wirken, überwindet jedoch das Problem nicht völlig.The use of gloves, a buffing or other similar Method of overcoming and increasing the friction between a gripper and the pipe can have a supportive effect, overcomes however, the problem is not entirely.

Der Erfindung liegt daher die Aufgabe zugrunde, bei Rohren aus Kunststoff die Übertragung eines Drehmoments zu ermöglichen.The invention is therefore based on the object of enabling the transmission of a torque in pipes made of plastic.

Dies wird erfindungsgemäß erreicht durch einen oder mehrere längsverlaufende Streifen auf der äußeren Oberfläche des Rohrs zur Vergrößerung von dessen Oberfläche, wodurch ein leichteres Ergreifen des Rohrs ermöglicht wird.According to the invention, this is achieved by one or more longitudinal stripes on the outer surface of the pipe to increase its surface area, making it lighter Gripping the tube is made possible.

Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung ist jeder längsverlaufende Streifen getrennt vom Rohr hergestellt und nach der Herstellung des Ronrs mit diesem vereinigt.According to a further advantageous development of the invention, each longitudinal strip is produced separately from the pipe and united with it after the production of the ronr.

Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung besteht jeder Streifen aus einem Kunststoff, der sich vom Kunststoff des Rohrs unterscheidet. Dabei kann jeder Streifen selbst mehrere längsgerichtete Oberflächenvorsprünge aufweisen.According to a further advantageous development of the invention there is any strip of plastic that is different from the plastic of the pipe. Each strip can itself have several have longitudinal surface projections.

Das Rohr kann aus vernetztem Polyolefin-Material oder wahlweise aus Polyvinylchlorid, Polybutylen, Polypropylen oder Polyäthylen bestehen»The tube can be made of crosslinked polyolefin material or optionally consist of polyvinyl chloride, polybutylene, polypropylene or polyethylene »

Die Streifen können auch aus thermoplastischem Material, in typischer Weise Polyäthylen oder Propylen, bestehen.The strips can also be made of thermoplastic material, more typically Polyethylene or propylene.

Die Streifen können mit unterschiedlichen Pigmenten oder Farbstoffen gefärbt werden, um ein Mittel für das Identifizieren der Art der Rohre und/oder Größe oder Qualität vorzusehen.The strips can be made with different pigments or dyes colored to provide a means of identifying the type of pipe and / or size or quality.

Gemäß der vorliegenden Erfindung können zwei oder drei längsgerichtete Streifen auf der Oberfläche eines Rohrs vorgesehen werden. Die praktische Erprobung hat gezeigt, daß das Vorsehen dieser Streifen ein Mittel ergibt ζar Schaffung eines verbesserten Griffs am Rohr für die Anwendung von Verbindungsanschlüssen und dergleichen.According to the present invention, two or three longitudinal Strips can be provided on the surface of a pipe. Practical testing has shown that the provision this strip gives a means of creating an improved one Handle on the pipe for the use of connection connections and the like.

Die vorliegende Erfindung beinhaltet auch ein Verfahren zur Herstellung eines Rohrs mit einem oder mehreren längsgerichteten Streifen auf dessen Oberfläche, das gekennzeichnet ist durch Strangpressen des Rohrs, durch Berühren einer im wesentlichen fortlaufenden Länge eines Streifens aus thermoplastischem Material mit der Oberfläche des Rohrs nach dem Strangpressen bei einer Temperatur, bei der sich das Rohr und/oder der Streifen über ihrem Erweichungspunkt befinden, durch Zusammenpressen des Streifens und des Rohrs und durch darauffolgendes Abkühlen, um ein Verschmelzen des Rohrs mit dem Streifen zu erzeugen.The present invention also includes a method of manufacture a tube with one or more longitudinal stripes on the surface thereof, which is characterized by Extruding the tube by contacting a substantially continuous length of strip of thermoplastic material with the surface of the tube after extrusion at a temperature at which the tube and / or the strip will be are above their softening point by compressing the strip and tube and then cooling to to create a fusion of the tube with the strip.

Eine weitere vorteilhafte Weiterbildung der Erfindung zeichnet sich dadurch aus, daß sich der Streifen auf Raumtemperatur und das Rohr auf einer Temperatur in der Größenordnung von 200 0C befinden, so daß eine Berührung des Streifens mit dem Rohr ein Schmelzen des Streifens ergibt, um ein Verschmelzen des Streifens mit dem Rohr zu erzeugen.Another advantageous development of the invention is characterized in that the strip is at room temperature and the tube is at a temperature of the order of magnitude of 200 ° C., so that contact of the strip with the tube results in a melting of the strip of the strip with the pipe.

Die Erfindung wird anhand der Zeichnung beschrieben. Darin zeigt:The invention is described with reference to the drawing. It shows:

Fig. 1 eine Schrägansicht des Rohrs gemäß der vorliegenden
Erfindung;Fig. 1 is an oblique view of the tube according to the present
Invention;

Fig. 2 eine schematische Ansicht der Vorrichtung für die Herstellung von Rohren gemäß der vorliegenden Erfindung.Fig. 2 is a schematic view of the manufacturing apparatus of pipes according to the present invention.

In Fig. 1 weist ein Rohr 10 aus vernetztem Polyäthylen eine
äußere Oberfläche 11 und auf dieser drei sich in Längsrichtung erstreckende Streifen 12 auf, von denen jeder aus thermoplastischem Polyäthylen hergestellt und mit dem vernetzten Polyäthylen des Rohrs 10 verschmolzen ist. Jeder Streifen hat eine unterschiedliche Farbe zur Identifizierung der Art und Qualität des Rohrs. Jeder Streifen ist aus einem halbkreisförmigen Streifen mit einer im wesentlichen halbkreisförmigen äußeren Oberfläche 13 geformt.In Fig. 1, a tube 10 made of crosslinked polyethylene has a
outer surface 11 and on this three longitudinally extending strips 12, each of which is made of thermoplastic polyethylene and fused with the crosslinked polyethylene of the tube 10. Each strip has a different color to identify the type and quality of the pipe. Each strip is formed from a semicircular strip with a substantially semicircular outer surface 13.

Das Rohr 10 aus vernetztem Polyäthylen wird für gewöhnlich durch Strangpressen hergestellt. Bei Verlässen einer Strangpresse 20 wird das eine Temperatur in eier Caröbenurünuiiy von 200 C aufweisende Rohr 21 über einen Tisch 22 mit einer darüberliegenden Platte 23 geführt. Von einer Rolle 24 wird Streifenmaterial 25 aus thermoplastischeKt Polyäthylen auf die Oberfläche des Rohrs zugeführt und für das Drücken des Streifens auf die Oberfläche unter der Platte 23 hindurchgeführt. Die Wirkung des in Berührung mit der heißen Wand des Rohrs 21 gedrückten Streifens 25
besteht in der Erweichung des dem Rohr zugewandten Teils des
Streifens und in der Ermöglichung einer dazwischen erfolgenden Verschmelzung. Nach dem Verlassen des Tischs 22 und der Platte 23 wird das Rohr 21 mit den auf der Oberfläche befindlichen
Streifen zum Abkühlen der Rohrwand durch ein Kühlbad 26 hindurchgeführt. Dann bewegt sich das Rohr mit dem oder den längsgerichteten Streifen auf seiner Oberfläche vom Kühlbad weiter
zum Aufwickeln auf eine Spule oder Trommel.The crosslinked polyethylene tube 10 is usually made by extrusion molding. When it leaves an extruder 20, the tube 21, which has a temperature in a carbene of 200 ° C., is passed over a table 22 with a plate 23 above it. Strip material 25 of thermoplastic Kt polyethylene is fed from a roll 24 onto the surface of the pipe and passed under the plate 23 for pressing the strip onto the surface. The effect of the strip 25 pressed into contact with the hot wall of the tube 21
consists in the softening of the part facing the pipe
In the strip and in the ability to merge in between. After leaving the table 22 and the plate 23, the tube 21 with the ones on the surface
Strip passed through a cooling bath 26 to cool the pipe wall. Then the tube moves on with the longitudinal strip or strips on its surface from the cooling bath
for winding on a spool or drum.
