摘要
FIELD: testing engineering.;SUBSTANCE: method comprises setting plugs into the branch pipes of the article to be tested, producing locking force by means of passing current through the winding of the electromagnet, and providing the article to be pressure-tight during the testing. The winding of the electromagnet is set into the housing of the plug that plays a role of magnetic circuit for the electromagnet. The plug comprises housing and member for producing locking force made of electromagnet having winding and magnetic circuit. The winding of the electromagnet is made of a multi-turn toroid and is set in the hollow in the housing of the plug.;EFFECT: enhanced reliability.;6 cl, 2 dwg
