Elbow

The innovation concerns a, 'Rohrkrünnner * especially for cast iron pipelines "

With the well-known pipe elbows, each with a specific one .Have angles, pipelines can be determined in the planning and delivered to the construction site »Unforeseen obstacles beicfer cable laying in the form of Sehmutz rain * or Gas pipes, heating ducts, cables or the like are used with pipe elbows of a known type in connection with appropriately cut to length Bypassed pipe sections. In most cases they are when pipe bends corresponding to such or similar obstacles • Not at hand or several elbows have to be put together with additional sealing points - which are the cause for leaks.

According to the innovation, these disadvantages are eliminated by the fact that a pipe bend consists of several straight pipe sections delimited at right angles to their axis, preferably of equal length, and of short intermediate pieces delimited at an angle to their axis in such a way that the pipe sections run at an angle to one another. Advantageously, for the connection of socket pipes, the length of each individual pipe section is approximately the sum of the lengths of the socket depth, the sealing ring and the sealing elements. In a further embodiment of the improvement, the assembly is provided by cams on the outer side and ^H-old element for anchoring clamps. ,

The use of such pipe bends is intended for unforeseen circumstances Pipe laying deviating from the planning and takes place at an angle less than 45 ° by cutting off the corresponding pipe section ^ so that every pipe bend can be made on the construction site »-

In the drawings, the pipe bends are shown j, namely demonstrate

Pig. 1 a pipe bend 45 ° with a socket connection in section Flg. 2 a pipe bend 33 3/4 ° iflit a screw connection in the Cut.

In Fig.! is a pipe elbow shown whose pipe sections 1 _P 2, 3 and 4, which are limited at right angles to their axis, correspond to angles 4-5, 35 3/4 * 22 1/2 and 11 ° »The pipe sections are limited by the intermediate pieces that are obliquely to their axis 5 * 6 $ 7 "&&& 8 connected to one another» & n the intermediate piece 8 is followed by a connecting piece 9 'in the form of a socket 9 or a veraubverbinäungsstückes Io. If, for example, a pipe bend at 45 ° is required on the construction site ^ at the interface, which is denoted by 11 in FIG. 2, is-fc, separated. -Locks 12 arranged on the pipe sections serve as holding elements for anchoring clamps "
