Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting equipment, in particular to a shot blasting device for the inner wall of a petroleum pipeline. Background Art

[0002] Oil pipelines are used to transport crude oil or refined products. They usually include pipes, connecting equipment, valves and control systems. Oil pipelines are usually made of steel pipes or other special alloys to withstand high pressure and have a certain degree of corrosion resistance. Oil pipelines play an important role in the oil industry. They are a key part of the energy production, processing and distribution system, ensuring that oil products are efficiently and safely delivered to where they are needed.

[0003] The medium transported in the oil pipeline is corrosive to a certain extent, so the requirements for the oil pipeline are relatively strict, and the requirements for the inner wall of the pipe are of utmost importance. Due to the large diameter of the pipe, traditional shot blasting equipment cannot meet the needs, and even manual entry into the pipeline is required for sandblasting. The sandblasting speed inside the pipeline is slow and the blasting is uneven, the force is relatively small, and the hardness requirements of the inner surface of the pipe cannot be met.

[0004] Therefore, the present application proposes a shot blasting machine with high blasting efficiency and uniform blasting force, which is suitable for blasting the inner wall of an oil pipeline to solve the above problems. Utility Model Content
