Description

Technical Field

[0001] This utility model relates to a two-end grinding device for processing stainless steel lined composite pipes, and belongs to the technical field of stainless steel lined composite pipe processing equipment. Background Technology

[0002] Stainless steel lined composite pipes typically consist of an inner wall made of stainless steel and an outer wall made of materials such as cast iron, which satisfies both corrosion resistance and certain mechanical properties.

[0003] When processing stainless steel lined composite pipes, the cross-sections at both ends need to be ground to remove burrs for subsequent processing when connecting to the outside environment. Previously, our company's processing method involved workers using a grinding machine to grind one end first, then the other, which was inefficient and the grinding quality could not be guaranteed. To solve this problem, our company's technicians have provided a grinding device for grinding both ends of stainless steel lined composite pipes. Utility Model Content
