<p>The invention relates to shaped sections for crossing pipes such as T-pipes or cross-pipes which are used for internal sewer system of various buildings. In the first variant, the shaped section of a polymeric sewer pipeline comprises a socket (1) provided with a collar (2) which has cylindrical (3) and end (4) sealing parts. A sealing ring (5) fixed by a locking ring (6) is arranged in the cylindrical sealing section (3). The inner part of the locking ring is provided with fixing grooves (7), an end sealing section (8) and a guide body (9), a fixing boss (10) being embodied on the surface of the collar (2). In the second variant, the shaped section of a polymeric sewer pipeline comprises a socket (1) provided with a collar (2) which is embodied such that it is composite in the form of an open cylindrical section provided with fixing grooves (11) arranged thereon. The sealing ring (5) is accommodated inside the collar (2) and fixed by the locking ring (6) which is provided with a fixing cone (9) arranged on the inner surface thereof. The outer surface of the locking ring (6) is provided, for example with two fixing bosses (12) which are embodied in such a way that they are can enter into the fixing grooves (11) of the cylindrical section of the collar (2). The end surfaces (13, 14) of the sealing ring (5), the end surface of the collar (2) and the locking ring (6) are embodied in such a way that they repeat the shape of the sealing ring (5).</p> |
