POLYMER PIPE ASSEMBLY AND METHOD OF ITS MOLDING Russian patent published in 2019 - IPC B29C65/08 B29D23/00 

FIELD: valve industry.

SUBSTANCE: invention relates to polymer pipe assembly. Technical result is achieved by a polymer pipeline assembly which includes a base component having first and second half components having respective first and second boundary surfaces formed along the oil passage, and first and second components, having respective third and fourth boundary surfaces, formed along oil channel, and which are connected to corresponding first and second half components, so as to form corresponding first and second sections of channel for oil channel. Each of the basic component and the first and second components is formed from the polymer material, and the first and second boundary surfaces are spaced apart along the length of the oil passage and unfold in the opposite directions, respectively. Basic component further includes a cylindrical pipe connection section having a connecting portion of the channel which is part of the oil channel and which is provided for communication between the first and second sections of the channel.

EFFECT: high degrees of freedom of configuring the oil channel configuration with high strength of binding constituent components.
