Copper Nickel CU NI 70:30 Tapered Tube Plug

Tapered Tube Plugs

Copper Nickel CU NI 70:30 Tube Plugging seal the ends of leaking tubes, providing longer use of the heat exchanger. The one-piece design of the pin plug provides an easy solution to permanent plugging for tubes or tubesheet holes. The uniform taper and the smooth surface finish assure positive sealing with minimum installation force.

Unique Advantage of Copper Nickel CU NI 70:30 Heat Exchanger Tube Plugs

1)       Special materials and sizes can be custom manufactured

2)      Can be machined to your drawing specifications.

3)      Good thermal conductivities and ductility down to cryogenic temperatures are Important features of Copper Nickel Plugs

4)     Copper Nickel Plugs make it somewhat more resistant to corrosion and erosion


Tapered Tube Plugs are used for permanent plugging of condenser and heat exchanger tubes and tubesheet holes. Tube Plugging can be used in some high temperature/pressure heat exchangers. Tube plugs driven into leaking tubes just before heat exchanger goes back into operation.
