▎ 摘  要

NOVELTY - The pipe has an outer wall anti-corrosion coating whose inner wall is provided with an inner layer anti-corrosion coating and an outer layer anti-static anti-corrosion coating. The inner layer anti-corrosion coating is located between a steel pipe and the outer layer anti-static anti-corrosion coating, where thickness of the outer wall anti-corrosion coating is measured about 2-4.2 mm, and thickness of the inner layer anti-corrosion coating layer is measured about 0.2-0.5 mm. USE - Anti-static anti-corrosion natural gas conveying steel pipe. ADVANTAGE - The pipe realizes better corrosion resistance of an inner wall of a natural gas conveying pipeline so as to reduce roughness of the inner wall of the natural gas conveying pipeline, thus improving conveying efficiency of the natural gas, hence reducing energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an anti-static anti-corrosion natural gas conveying steel pipe manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of an anti-static anti-corrosion natural gas conveying steel pipe.
