METHOD FOR RADIAL REAMING OF PIPE CONNECTOR

摘要

FIELD: mining, particularly for well drilling, for instance for pipe string, namely casing pipe, reaming. ^ SUBSTANCE: method involves expanding pipe connector adapted to connect two pipes in radial direction. Pipe connector comprises nipple member having end part located at opened end thereof and clutch member. Nipple and clutch members have cooperating support means. Nipple member is fixed to prevent inward end part displacement in radial direction during and after connector reaming. ^ EFFECT: elimination of pipe connector deformation during reamer passage through the pipes. ^ 10 cl, 3 dwg
