| description | The utility model belongs to the improvement of a plastic pipeline connecting flange structure, in particular to an improved thermoplastic plastic pipeline connecting flange. The improved thermoplastic plastic pipeline connecting flange comprises flange plates which are evenly distributed on a circular ring disc surface and provided with connecting holes. The improved thermoplastic plastic pipeline connecting flange is characterized in that sealing surfaces are arranged on basic flat surfaces of the flange plates located in the inner sides of the connecting holes, and the sealing surfaces are conical surfaces, wherein the sections of the sealing surfaces form included angles with the basic flat surfaces of the flange plates; circular convex rings are evenly distributed on the sealing surfaces, wherein the sections of the circular convex rings are sawtooth-shaped, sawtooth-shaped vertical sides of the circular convex rings are located on the outer sides of the flange plates, and sawtooth-shaped inclined sides |
