Collateral damage from another leaking tube

External Appearance

Typically sharply cut or wasted tubing resulting from steam erosion; however some collateral damage may present itself in the form of dents or bowed tubing. 

Micrograph images of steam washing show that any surface slag is removed. The surface is eroded to a smooth finish. 

Adjacent leaks of steam or water erode slag and tube material from the OD surface. Tubes thin to a point where they could not withstand the internal steam/water pressure and rupture with plastic deformation. Typically, they exhibit overload ruptures or pinhole failures.   

Corrective action:
Replace the leaking tube and repair collateral damage as necessary.


After any leak, all tubes in the general area must be inspected for steam washing damage.

Common Locations: All tubes vulnerable
