METHOD AND SYSTEM FOR TREATING A STEEL TUBING WITH A COATING TO RESIST CORROSION

摘要

A method of treating a steel tubing with a coating to resist corrosion includes passing a steel tubing through a trough of molten zinc-aluminum alloy. The method additionally includes establishing a magnetic field with an electrical current and adjusting the electric current to adjust a thickness of zinc-aluminum alloy coating on the steel tubing. The method further includes passing the steel tubing through the magnetic field. A steel tubing treated with the method may include a zinc-aluminum coating having a thickness of at least approximately 10pm and preferably at least approximately 15µm.
