Precision Inner Recess Groove Round Hollow Steel Tube

Precision inner groove circular tube   Our factory specializes in the research and production of precision inner groove circular hollow steel pipes, which are high-end cold drawn shaped pipes commonly used in industrial machinery, hydraulic systems, and precision transmission equipment. The product adopts an integrated cold drawing forming process, with a regular and round outer circumference, high concentricity, standard inner wall groove forming, uniform and symmetrical groove shape, and consistent depth. The overall pipe wall is dense and uniform, with strong structural rigidity and precise dimensional tolerances, effectively solving common problems such as large clearance between ordinary circular pipe shaft sleeves, easy transmission slippage, easy positioning deviation, and easy assembly loosening. Unlike external groove pipes, the internal groove structure has stronger concealment and better overall appearance, without affecting the conventional installation adaptability of ext…
