Abstract

FIELD: mining. SUBSTANCE: method for manufacture of shaped shutoff devices includes shaping of pipe by its drawing through shape forming tool. One end of pipe is flared out, pipe is shaped on length part beginning from flared out end, and its other cylindrical end is upset to diameter of circumscribed circle of shaped part of pipe and thread is cut. EFFECT: higher efficiency of application of shaped shutoff devices in well due to exclusion of sealing heads.
