Honed tube is the steel tube that with inner diameter have been honed or polished to achieve a smooth surface finish and tight dimensional tolerances. As honed tube is mostly used a hydraulic cylinder tube, so the high quality honed tube is critical to the quality of the hydraulic cylinders, but what honed tubes are with high quality?
High-quality honed tube has several characteristics, including:
- High smoothness surface finish: High-quality honed tube should have a smooth and uniform surface finish, free from any roughness, scratches, or other defects that could affect their performance. The surface roughness should be better than Ra 0.4μm.
- High precision accuracy of dimensions: The inside diameter, outside diameter, and wall thickness of honed tube must be precise and consistent to ensure proper fit and function.
- Straightness: Honed tube should have excellent straightness to prevent any deformation or bending during use.
- Hardness: The hardness of honed tube should be appropriate for their intended use. Tubes used for high-pressure applications, for example, require greater hardness to withstand the stress.
- Material quality: The material used to make honed tubes should have high strength, durability, and resistance to corrosion and wear. Common materials include stainless steel, carbon steel, and alloy steel.
- Surface hardness depth: The surface hardness depth of honed tube should be uniform and consistent.
- Microstructure: High-quality honed tubes have a fine and uniform microstructure, with no defects such as porosity, cracks, or inclusions.
Overall, high-quality honed tube should have excellent surface finish, dimensional accuracy, material quality, straightness, hardness, surface hardness depth, and microstructure. Honed tube is the critical material for hydraulic cylinder manufacturing and repairing, it is widely used as hydraulic cylinder barrel. So to ensure the quality of hydraulic cylinder, it is very important to use high quality honed tubes.
