Embodiment Construction

[0029] In Figures 1, 3, 5 and 7 a single layer embodiment of the delivery pipes 1, 2, 3, 4 is shown, in contrast to this Figures 2, 4, 6, 8 show the delivery pipes 5, 6, 7, 8 double layer implementation.

[0030] The delivery pipes 1 , 2 , 3 , 4 have a single-layer pipe body 9 made of highly wear-resistant hardened steel. In contrast, the delivery pipes 5 , 6 , 7 , 8 are designed as a double-layer pipe body 10 consisting of a highly wear-resistant hardened inner pipe 11 and a pressure-resistant outer pipe 12 .

[0031] A connecting ring 15 is fastened to each end 13, 14 of the tubular bodies 9 and 10 by a full-surface adhesive bond. The connecting ring 15 , viewed in the direction of the longitudinal tube axis LA, has a first ring section 16 on the end side and a second inner ring section 17 pointing towards the tube center M, between which a trapezoidal coupling groove 18 is formed. . It can be seen that the wall thickness s1 of the first ring segment 16 is smaller than th...

Abstract

The invention relates to a delivery pipe (1) for transporting solid materials, said delivery pipe comprising a tubular body (9) provided with a coupling shoulder (15) on each end (14). Said coupling shoulder (15) comprises a free region (21) on the inner peripheral surface (IB) thereof, on the end (20) thereof opposing the front side (19) thereof. A sealing body (22) is arranged in the free region (21). The invention also relates to a method for fixing a coupling shoulder to an end of the tubular body of a delivery pipe by adhesion. Said method is characterised in that a sealing body is arranged on an outer peripheral surface of the tubular body, and the outer peripheral surface between the sealing body and a front side is coated with an adhesive. The coupling shoulder or the tubular body is then rotated about the longitudinal axis of the pipe, and the coupling shoulder is pushed against the end of the tubular body or vice versa. The sealing body is then pushed into a free region of the coupling shoulder.

Description

technical field [0001] The invention relates to a conveying pipe for conveying solids, comprising a pipe body with a connecting ring fixed at each end by means of gluing, and to a conveying pipe for conveying solids by means of gluing. The method by which a connecting ring is secured to the body end of a delivery tube. Background technique [0002] Solids such as building materials, cement, gravel or sand are conveyed pneumatically or hydraulically in lines consisting of a plurality of conveying pipes connected to each other. To connect these delivery tubes, the delivery tubes are each provided with a connecting ring at the end. Via the connecting ring, the connection of the delivery pipe takes place either via a connecting clip or via a screw on a connecting ring provided with holes. [0003] On almost exclusively delivery pipes currently used in practice, the connecting ring is welded to the pipe body. However, thermal influences during the welding process can cause unf...
