Description

Rohr aus Faserstoffen und hydraulischen Bindemitteln, insbesondere Asbest und Zement Die Erfindung bezieht sich auf Rohre aus Faserstoffen und hydraulischen Bindemitteln, insbesondere aus Asbest und Zement. Derartige Rohre sind leicht und bequem zu-verlegen und besitzen eine große Widerstandsfähigkeit gegen hohe Drücke. Ihre Verwendungsmöglichkeit ist dagegen beschränkt durch chemische und mechanische Eigenschaften des Rohrmaterials. Starke Säuren vermögen die Rohrwandung anzufresser@, und wenn die Rohre nicht zur Förderung von Flüssigkeiten allein, sondern auch von festen Körpern, wie Sand, kleinen Steinen u. dgl., dienen, werden. ihre Wandungen durch diese Körper leicht beschädigt.Pipe made from fibrous materials and hydraulic binders, in particular Asbestos and cement The invention relates to fibrous and hydraulic pipes Binders, in particular made of asbestos and cement. Such pipes are light and easy to lay and have a high resistance to high pressures. Their possible uses, however, are limited by chemical and mechanical factors Properties of the pipe material. Strong acids can corrode the pipe wall @, and when the pipes are not used to convey liquids alone, but also of solid bodies such as sand, small stones and the like. their walls easily damaged by these bodies.

Der Zweck der Erfindung ist, diese Nachteile zu beseitigen und. ein Asbestzementrohr vorzusehen, das sowohl zur Förderung von säurehaltigen Flüssigkeiten oder Gasen als auch von festen Körpern Verwendung finden kann. Dies wird dadurch erreicht, daß das Rohr mit einem. Gummiüberzug versehen wird. Versuche haben gezeigt, daß sich Gummi,wider Erwarten gut und innig mit dem ihm völlig wesensfremden Asbestzement verbindet. Die Anbringung des Gummiüberzuges braucht nur auf der Innenseite des Rohres zu erfolgen, jedoch kann es, z. B. bei Verlegung der Rohre in stark säurehaltigen Boden, von Vorteil sein, auch außen auf dem Rohr einen Gummiüberzug anzubringen. Durch die Anbringung des Gummiüberzuges werden die günstigen Eigenschaften des Asbestzementrohres nicht verändert, wohl aber werden die Nachteile aufgehoben, die gewöhnlichen Asbestzementrohren anhaften.The purpose of the invention is to eliminate these drawbacks and. a Asbestos-cement pipe to be provided, both for the conveyance of acidic liquids or gases as well as solid bodies can be used. This is because of this achieved that the pipe with a. Rubber coating is provided. Tests have shown that rubber, contrary to expectations, blends well and intimately with the asbestos cement, which is completely alien to it connects. The rubber cover only needs to be attached to the inside of the Rohres to be done, however, it can, for. B. when laying the pipes in highly acidic On the ground, it may be advantageous to apply a rubber cover to the outside of the pipe. By attaching the rubber coating, the favorable properties of the asbestos-cement pipe are achieved not changed, but the disadvantages are eliminated, the ordinary asbestos-cement pipes cling.

Das Aufbringen des Gummiüberzuges kann in beliebiger Weise, z. B. durch Aufvulkanisieren, erfolgen. Um eine besonders große Säurebeständigkeit des Rohres zu erzielen, ist es vorteilhaft, den Überzug aus Hartgummi herzustellen, während sich zur Erhöhung der Verschleißfestigkeit das Aufbringen einer weicheren Gummiqualität empfiehlt. Bei mit Hartgummiüberzügen versehenen säurefesten Rohren hat sich ein Gummiüberzug von einigen Millimetern, etwa bis zu 6 mm, als ausreichend .erwiesen. Bei mit Weichgummi`ausgekleideten verschleißfesten Rohren empfiehlt es sich dagegen, für den Überzug eine größere Dicke, bis etwa i cm, zu wählen.The application of the rubber coating can be done in any way, e.g. B. by vulcanization. To ensure that the To achieve pipe, it is advantageous to make the coating of hard rubber, while to increase the wear resistance the application of a softer one Recommended rubber quality. For acid-proof pipes with hard rubber covers a rubber coating of a few millimeters, up to about 6 mm, has proven to be sufficient .proven. It is recommended for wear-resistant pipes lined with soft rubber opposed to choosing a greater thickness for the coating, up to about 1 cm.

Durch die Anbringung eines Gummiüberzuges ist es erstmalig möglich geworden, Asbestzementrohre mit Erfolg als Spülversatzrohre und in chemischen Fabriken als Förderrohre für unter Druck stehende Säuren zu benutzen.It is possible for the first time by attaching a rubber cover Asbestos-cement pipes have become successful as flushing pipes and in chemical factories to be used as delivery pipes for pressurized acids.
