A pipe is arranged as elongated shell (10), has connected to each other inner wear-proof layer (11) made of rubber, and outer protective layer (12) placed between those (11, 12) flexible cords (14) and end connection elements (15) for connection to neighboring pipes or pipeline fittings. According to the invention the shell (10) additionally has at least one side branch pipe (20) that is hermetically joined and connected to the shell (10) that has inner wear-proof layer (21) made of rubber, outer protective layer (22) and placed between those (21, 22) flexible cords (24). Near the shell (10) flexible cords (14) are arranged as cross and long layers (14a, 14b) of cords (14), end connection elements (15) have circular frames (15b) connected to long layers (14b) of cords (14) in such way that long layers (14b) of cords (14) with loops (14c) surround those circular frames (15a) of end connection elements (15) at whole length, at that cross and long layers (14a, 14b) of cords (14) are placed with crossing, and the outer protective layer (12) is made of rubber and covers outer surfaces of the shell (10) of pipe and its end connection elements (15). In each branch pipe (20) flexible cords (24) are arranged as cross and long layers (24a, 24b) of cords (24), at that cross and long layers (24a, 24b) of cords (24) are placed with crossing and the outer protective layer (22) is made of rubber. Improved design of pipe has additional outlet channels, long yielding and transverse flexibility, and elastic fixation of end connection elements, this increases functional possibilities at increase of operation reliability and term of operation of multi-layer elastomer pipe. |
