Method for forming a layer of synthetic corrosion products on tubing surfaces

A method for forming a layer of synthetic corrosion products on tubing surfaces, said method comprising the steps of:

• selecting an object tube and a sacrificial tube, said sacrificial tube having a thermal expansion coefficient which is greater than said object tube;
• placing said object tube and said sacrificial tube so as to be disposed circumjacent, one about the other, and thereby creating an annular region between said object tube and said sacrificial tube, said object tube enclosing said sacrificial tube, thereby having said annular region within said object tube and in communication with an inner surface of said object tube;
• filling said annular region with a sludge slurry;
• and
• heating at least said sacrificial tube so as to expand said sacrificial tube, said sacrificial tube thereby exerting pressure on said sludge slurry and thereby adhering a synthetic corrosion product from said sludge slurry onto said object tube.

• placing said object tube and said sacrificial tube so as to be disposed circumjacent, one about the other, and thereby creating an annular region between said object tube and said sacrificial tube, said sacrificial tube enclosing said object tube, thereby having said annular region outside of said object tube and in communication with an outer surface of said object tube;
• filling said annular region with a sludge slurry;
• and
• heating at least said object tube so as to expand said object tube, said object tube thereby exerting pressure on said sludge slurry and thereby adhering a synthetic corrosion product from said sludge slurry on said object tube.
