Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing, in particular to a polishing device for processing nickel-based alloy pipes. Background Art

[0002] Nickel-based alloy refers to a type of alloy with comprehensive properties such as high strength and certain resistance to oxidation and corrosion at high temperatures of 650-1000°C. It has replaced Ti-stabilized stainless steel and is widely used in pipe manufacturing. Nickel-based alloy pipes need to go through many processes during the processing, among which nickel-based alloy pipes need to be polished.

[0003] The existing nickel-based alloy tube polishing device often polishes the outer wall of the nickel-based alloy tube alone during polishing, which is inconvenient to polish the inner wall of the nickel-based alloy tube and has low polishing efficiency. Therefore, we propose a nickel-based alloy tube processing polishing device. Utility Model Content
