FIELD: pipeline transportation systems. SUBSTANCE: this can be used in oil, gas, petrochemical and other branches of economy where pipeline transportation systems are employed. Device has dispatching-receiving chamber which at one end is provided with end lock which is made up of cover and tipping half-yokes tightened together by screw, and with trough for inlet and outlet of transported fluid, and other end it is made with eccentric adapter, pipe union and brunch pipe with bushed union made of spark-proof material with small end lock of up to 200 mm inner diameter for dispatching fluid medium. Aforesaid union is located on horizontal axis of chamber. Located inside it is member which is removable and fixable in preset position with external bottom conjugated with inner surface of branch pipe. Tipping half-yokes of chamber end lock are mounted on axles displaced vertically upward and down relative to horizontal axis of chamber. Branch union of chamber has straight sections at ends and is of length and curvature radius ensuring free passing of fluid flow and permitting welding with linear part of pipeline in field conditions. Chamber is inner diameter equal to 1.14 of inner diameter of pipeline. Adapter and pipe union of chamber are of up to 400 mm length. Device is manufactured in factory conditions which makes it more reliable. EFFECT: high efficiency. 4 cl, 4 dwg
