Plugs for heat exchangers and condenser tubes

If a tube should be found extremely damaged during inspection, it must either be replaced or sealed off: “plugged”. 

Conventional sealing options usually include welding up of affected tubes as well as driving or screwing in plugs. DELTA TEST offers its customers a plug system up to max. 140° C operating temperature, with which the plugs can be inserted quickly and easily, and later be removed again without further damage of the tubes or the heat exchanger.

Inserting the plugs for secure sealing of the pipes is fast and straightforward, special tools or personnel is not required. Upon customer request, we seal damaged tubes directly after testing.
