Steel pipe inner wall anti-corrosion A device used for the inner wall anti-corrosion device of the welded joint of the inner coated steel pipe, which is characterized in that a sacrificial anode made of lead, magnesium, zinc, or its alloy is connected to a terminal made of conductive metal material. The terminal the outer edge is placed between the two steel pipe joints. After welding, it becomes a definite connection with the steel pipe. The device implements sacrificial anode protection on the discontinuous part of the inner wall coating of the welding part. Thereby realizing the overall steel pipelining the inner wall is anti-corrosive. Its structure is easy too, easy to install, low cost, protection degree reaches 95-100%, and the service life is 5-20 years. An anti-corrosion device for the inner wall of a steel pipe using a sacrificial anode to protect the inner wall of the welded joint of the lined steel pipe. The inner wall of the steel pipe is characterized by a sacrificial anode made of aluminum, magnesium, zinc or their alloys
(1) Connected to the terminal made of conductive metal material
(2) The outer edge of the upper terminal is placed between the two steel pipe joints and becomes a firm connection with the steel pipe after welding.
