INTER-TUBE INSPECTION TOOL AT CONTROLLABLE SPEED OF MOTION

摘要

FIELD: inter-tube tools for inspection of pipe lines at high stabilization of speed of motion. ^ SUBSTANCE: proposed tool has cylindrical body with front and rear supports in form of circular collars mounted between body and pipe line, tool speed sensor, control unit and drive for adjustment of gas bypass. Tool is provided with bypass system including six double-loop gas bypass sections with central passage provided with nozzle and passage of second loop having nozzle in form of deflector and throttle valve secured in one module in tool body. ^ EFFECT: enhanced stabilization within preset limits flaw detector speed due to outflow of gas in nozzles. ^ 3 dwg
