  • Corrosion resistant tube and method of manufacture
    Patent number: 12687252
    Abstract: A corrosion resistant tube includes a tubular low carbon steel body having an inside surface and an outside surface, a corrosion resistant metal coating on the inside surface, a first corrosion resistant metal coating on the outside surface, a second corrosion resistant metal coating applied to the first corrosion resistant metal coating on the outside surface, and a polymer layer applied over the second corrosion resistant metal coating. A method of manufacturing a corrosion resistant tube, includes applying a corrosion resistant metal coating both sides of a strip of low carbon steel, forming the strip into a tube and welding the edges to form a tubular body. The weld is narrower at the inside surface than at the outside surface of the tubular body. The corrosion resistant metal coating on the inside surface is heated during welding and flows across and covers the weld.
