DEVICE FOR CLEANING AND INSPECTING INNER CAVITY OF PIPELINE Russian patent published in 2025 - IPC B08B9/04 

FIELD: performing operations.

SUBSTANCE: invention relates to devices for cleaning of hollow items by means of devices moving in them, removal of deposits from cavity of pipeline so that control of technical condition of in-field pipelines is provided. Device is made in the form of a chamber with flanges built into the transport pipeline for connection to the pipeline with a bypass line, shutoff valves and in-line device, wherein on the main transport pipeline to be periodically cleaned or inspected, at least two chambers are built-in, two coil units, one at the beginning of the pipeline for starting the in-line device, the other at the end of the cleaned pipeline section for receiving the in-line device, which are made in the form of a pipe section with connecting flanges, each coil unit is equipped with an additional bypass pipeline, wherein coil farthest edge to receive in-tube device is provided with inter-flange grid for catching in-tube devices with tube dead-end section arranged behind said screen to collect slime cleaned from tube cavity.

EFFECT: simplification of the design and expansion of technological capabilities by using a device with provision for collection and removal of sludge, with the possibility of conducting pipeline inspection.
