Torq'N Seal Plugs
Positive sealing in excess of 6500 PSI is achieved without special tooling or personnel training.
Plug can be inserted to any depth of the tube sheet in order to avoid severely corroded areas on the tube sheet face.
Design enables rapid implantation and fit into tight areas adjacent to the tube sheet/shell joint interface, baffle plates and internal dividers.
One piece design enhances sealing characteristics by eliminating second potential leak path common to design found in two piece plugs.
Wide sealing area contact zone ensures a positive seal while the gradual and symmetrical torque expansion eliminates thermal and mechanical shock to the tube sheet, commonly found with welding, impact due to hammering of tapered pins, and explosive insertion methods.
Exclusive design allows installation of plugs at the face and back side of the tube sheet in order to prevent intrusion of shellside corrosives. With single plugging techniques accomplished on the face of the tube sheet, corrosives can enter the void created in the tube sheet thereby exacerbating erosion and corrosion of the tube sheet ligaments.
Torq'N Seal Plugs are available to meet Nuclear or ISO 9002 QA specifications.
