Mantel aus Wellpappe für gegen Wärme- und Kälteverluste isolierte RohreNorth German Isolierwerke Kreuser & Klostermann in Hanover-Linden
Corrugated cardboard jacket for pipes insulated against heat and cold losses

Patentiert im Deutschen Reiche vom 17. Juli 1937 ab
Patenterteilung bekanntgemacht am 11. Januar 1940Patented in the German Empire on July 17, 1937
Patent issued January 11, 1940

Die Wellen von Mänteln für gegen Wärme- und Kälteverluste isolierte Rohre wurden bisher gegen mechanische Beschädigungen und gegen Formänderungen dadurch gesichert, daß eine flüssige Masse in die durch die Wellen und ihre Unterlage gebildeten Hohlräume eingespritzt oder durch Eintauchen der Wellpappe eingeführt wurde. Diese Art der Einführung war unzuverlässig, weil die Masse bei der Einspritzung die Wellen sprengen konnte und beim Eintauchen nicht gleichmäßig über die ganze Wellenlänge verteilt wurde.The waves of jackets for pipes insulated against heat and cold losses have been used up to now secured against mechanical damage and changes in shape in that a liquid mass is injected into the cavities formed by the shafts and their base or by dipping the corrugated cardboard. That kind of introduction was unreliable because the mass could burst the waves during the injection and during the Immersion was not evenly distributed over the entire wavelength.

Nach der Erfindung sollen die Ubelstände dadurch behoben werden, daß als versteifende und formerhaltende Masse Stäbchen oder Röhrchen aus Holz ο. dgl. in die durch die Wellen und ihre Unterlage gebildeten Hohlräume hineingeschoben werden.According to the invention, the Ubelstands are to be eliminated in that as a stiffening and shape-retaining material sticks or tubes made of wood ο. like. in by the waves and their base formed cavities are pushed into it.

In der Zeichnung ist ein gegen Wärmeao und Kälteverluste isoliertes Rohr mit einem Mantel aus Wellpappe nach der Erfindung in einem Querschnitt dargestellt.In the drawing is a against heat ao and cold losses insulated pipe with a jacket made of corrugated cardboard according to the invention in FIG shown in a cross section.

Um das Rohr α wird der gegen Wärme- und Kälteverluste isolierende Stoff b durch einenTo the tube α is the insulating against heat and cold loss substance b by a

Mantel c, d aus Wellpappe in an sich bekannter 25 Weise zusammengehalten. Die Hohlräume, welche die Wellen,c mit ihrer Unterlage^ bilden, erhalten eine versteifende Füllung; diese besteht gemäß der Erfindung aus einem Stäbchen oder Röhrchen e aus Holz o. dgl., das in die Hohlräume 30 hineingeschoben wird. Besteht die Füllung aus einem Röhrchen, so erhöht es die isolierende Rohrumhüllung durch die in ihm enthaltene Luft.Sheath c, d made of corrugated cardboard held together in a known manner. The cavities which the corrugations, c form with their base, receive a stiffening filling; According to the invention, this consists of a rod or tube e made of wood or the like, which is pushed into the cavities 30. If the filling consists of a tube, it increases the insulating tube envelope through the air it contains.

Die Wellpappe wird vorteilhaft in bekannter 35 Weise mit wasserdicht machenden Stoffen getränkt. The corrugated cardboard is advantageously impregnated with waterproofing substances in a known manner.
