CONTROL OVER PIPELINE CLEANING AND DEVICE TO THIS END Russian patent published in 2014 - IPC B08B9/04 

FIELD: process engineering.

SUBSTANCE: invention relates to pipeline cleaning at in-pipe diagnostics and can be used for detection of pipeline clogging and pipeline availability for in-pipe ultrasound fault finder passage. Proposed device comprises casing composed by the bar with several flanges attached thereto. Note here that weights and bumper are secured to front two flanges while polyurethane conical skids assembled with cylindrical skids are secured to third flange. Said polyurethane conical skids and cylindrical skids support ultrasound transducer simulators while said polyurethane conical skids are composed by resilient bearing elements with polyurethane cylindrical skids jointed together by leaf springs and bolts with washers. Proposed method consists in pushing the cleaning check device through the pipeline. Note that said device is driven via collars by the flow of transferred product. At device passage over pipeline section, wax solid fractions and soil particles entrapped by oil get settled on ultrasound transducer simulator surface. Said device withdrawn from pipeline intake chamber, total quantity of ultrasound transducer simulators and that of three and more adjacent simulators coated with wax are calculated.

EFFECT: higher reliability and validity of flaw detection, ruled out damage of ultrasound diagnostics hardware.
