Abstract

A corrosion fuse is a device connected with a compressed air tank in order to provide a predictive indication of corrosive activity occurring within the compressed air tank. The corrosion fuse includes a corrosion detector established as a thin-walled metal tube closed on one end and open to an environment outside the compressed air tank on the other end. The joining of the corrosion fuse with the compressed air tank is enabled by the connection of a plug with a fitting (i.e., flange). The plug connects to the open end of the corrosion detector and with the flange. The flange is connected to the compressed air tank about a tank receiver disposed on the compressed air tank. The tank receiver allows the corrosion detector, connected with the plug, to at least partially extend inside the compressed air tank, when the plug is connected with the flange.

Claims (27)

1. A corrosion fuse for use in a compressed air tank formed of a corrodible material, the corrosion fuse comprising:

a corrosion detector formed of substantially the same corrodible material as that of the compressed air tank, the corrosion detector mounted through a wall of the compressed air tank for storing air at an elevated pressure and extending substantially into an interior of the compressed air tank,

wherein the corrosion detector provides a predictive indication of a pre-determined amount of corrosion occurring generally at a waterline.

2. The corrosion fuse of claim 1 , wherein the predictive indication is correlated to a pre-determined amount of corrosion having occurred to the compressed air tank.

3. The corrosion fuse of claim 1 , wherein the corrosion detector defines a recess which is configured to be exposed to an environment outside the compressed air tank.

4. The corrosion fuse of claim 1 , further comprising a plug which connects with the corrosion detector.

5. The corrosion fuse of claim 4 , further comprising a flange which connects with the compressed air tank and the plug.

6. The corrosion fuse of claim 1 , further comprising an indication system which is at least one of a visual indication system and an audible indication system.

7. The corrosion fuse of claim 1 , further comprising at least one tamper resistant feature.

8. A corrosion fuse for use in a compressed air tank formed of a corrodible material, the corrosion fuse comprising:

a plug;

a corrosion detector formed of substantially the same corrodible material as that of the compressed air tank, and connected to the plug, the corrosion detector extending substantially into an interior of the compressed air tank for storing air at an elevated pressure;

wherein the corrosion detector provides a predictive indication of a pre-determined amount of corrosion occurring generally at a waterline.

9. The corrosion fuse of claim 8 , wherein the predictive indication is correlated to a pre-determined amount of corrosion having occurred to the compressed air tank.

10. The corrosion fuse of claim 8 , wherein the corrosion detector defines a recess which is configured to be exposed to an environment outside the compressed air tank.

11. The corrosion fuse of claim 8 , further comprising a flange which connects with the compressed air tank and the plug.

12. The corrosion fuse of claim 8 , further comprising an indication system which is at least one of a visual indication system and an audible indication system.

13. The corrosion fuse of claim 8 , further comprising at least one tamper resistant feature.

14. A corrosion fuse for use in a compressed air tank, comprising:

a compressed air tank formed of a corrodible material, the compressed air tank for storing air at an elevated pressure; and

a corrosion detector formed of substantially the same corrodible material as that of the compressed air tank, the corrosion detector mounted through a wall of the compressed air tank and extending substantially into an interior of the compressed air tank;

wherein the corrosion detector provides a predictive indication of a pre-determined amount of corrosion having occurred generally at a waterline inside the compressed air tank.

15. The corrosion fuse of claim 14 , wherein the position of the corrosion detector in the compressed air tank corresponds to a lowest gravitational point in the compressed air tank.

16. The corrosion fuse of claim 14 , further comprising a plug connected to the corrosion detector.

17. The corrosion fuse of claim 16 , further comprising a flange connected to the compressed air tank, the flange being connected with the plug connected to the corrosion detector.

18. The corrosion fuse of claim 14 , further comprising an indication system including at least one of a visual indication system and an audible indication system.

19. The corrosion fuse of claim 14 , further comprising at least one tamper resistant feature.
