Claims (1)
鋼の基材表面にクローム、アルミニウム、モリブ
デン等の金属粉末をアンダコートとして溶射によ
り被膜を形成し、該被膜表面にスポツト溶接によ
り上記基材表面と溶射層の合金層を形成後更に上
記被膜表面に良耐食性の金属粉末からなる被膜を
形成したことを特徴とする被覆伝熱管。 A coating is formed by thermal spraying as an undercoat with metal powder such as chromium, aluminum, or molybdenum on the surface of the base material of carbon steel or low alloy steel that constitutes the heat exchanger tube for a boiler, and the surface of the base material is bonded to the surface of the base material by spot welding. A coated heat exchanger tube characterized in that, after forming the alloy layer of the sprayed layer, a coating made of metal powder having good corrosion resistance is further formed on the surface of the coating.
