Description

Technical Field

[0001] The utility model relates to the technical field of metal pipes, in particular to a metal wear-resistant pipe with an inner anti-corrosion coating. Background Art

[0002] Wear-resistant pipe transportation has spread to the power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and is developing at a high speed. Wear of wear-resistant pipes is a common phenomenon. Any surface where two objects are in contact and have relative motion will wear. Pipeline wear refers to the wear phenomenon caused by the detachment or transfer of the material surface when the pipeline material is impacted by flowing water and small and loose particles.

[0003] Traditional metal wear-resistant pipes are one-piece pipes. Since the pipes are long as a whole, it is not convenient to clean the scale accumulated inside. Over time, it will cause corrosion to the inside of the pipes and cause damage to the pipes. Moreover, since the pipes are one-piece molded, if one part of the pipe is damaged, the entire pipe will be scrapped, resulting in a large loss.

[0004] Therefore, those skilled in the art provide a metal wear-resistant pipe with an internal anti-corrosion coating to solve the problems raised in the above background technology. Utility Model Content
