FIELD: testing facilities. SUBSTANCE: invention can be used for testing pipelines for tightness. Proposed sealing head consists of housing in form of hollow rod on one end of seal is mounted. Other end of rod is installed in spherical joint for axial displacement. Joint is installed in housing secured on axle whose displacement is limited by stop whose upper part is made in form of cone with angle smaller than self-braking angle. Design of proposed sealing head provides high degree of reliability of pipe sealing at testing owing to maintaining axial alignment of pipe under testing and sealing head. EFFECT: improved reliability of testing. 2 dwg
