Connection with a steel flange for a plastic pipe, in particular a seamless connection for a pressure PE gas pipe

摘要

The attachment to the plastic pipeline with a steel collar, in particular the attachment to the PE gas pipeline pressure tube, has a steel collar and a section of the plastic pipeline attached to it, which is a section of the plastic pipeline which is compressed from the inside of the tube with a circular shaft in the form of a shot at the outer surface of the metal casing, which pushes the outer surface of the section of the transmission tube to the peripheral selections on the surface of the post-axis channel in conjunction with the connecting holes on the standard partition diameter,where the surface of the end of the conveyor pipe, which is compressed from the inside of the housing, is represented by the surface of the post-suction duct in the collar, is characterised by a neck collar,on the surface of its posterior canal it has peripheral selections (30) with a triangular shape with a shorter side of the neck in parallel planes to the flange plane (2a) and on the side (21) opposite the flange (2a) gradually increasing the diameter of the canal to a greater dimension (df) than the diameter (Dz) transmission tube (4).
