    What is Honed Tube?

    A Honed Tube is a precision-engineered seamless steel pipe processed by honing to achieve ultra-smooth inner surfaces (Ra ≤ 0.4μm) and tight dimensional tolerances (±0.05mm). Widely used in hydraulic cylinders, pneumatic systems, and engineering machinery, it ensures minimal friction, leak-free sealing, and extended component lifespan under high-pressure conditions. Made from materials like ST52 or 42CrMo4, it withstands fatigue and impact loads, making it ideal for excavators, cranes, and industrial equipment. Chengxin, a leading manufacturer, offers customized honed tubes with strict quality control, serving global clients in automotive, construction, and energy sectors.
