Seamless Honed Tube<\/strong> (also known as honed seamless pipe, hydraulic cylinder honed tube, precision honed pipe<\/em>) is a high-precision steel tube manufactured from high-quality seamless steel pipe through cold drawing \/ cold rolling and precision honing processes. With high dimensional accuracy, mirror-bright inner surface, high pressure resistance, and zero leakage<\/strong>, it is widely used in hydraulic & pneumatic systems, construction machinery, automotive, petroleum, chemical, aerospace and other industries. It is the core material for hydraulic cylinders, pneumatic cylinders, and precision transmission components.<\/div>\n

Key Advantages of Our Seamless Honed Tube<\/h2>\n
<\/div>\n
    \n
  1. \n
    \n

    Ultra-High Precision<\/strong><\/p>\n

    <\/div>\n

    Inner diameter tolerance H7\/H8<\/strong>, ovality \u2264 0.01mm<\/strong>, straightness up to 1\u20131.2mm\/1000mm<\/strong>, ensuring perfect fit for high-speed reciprocating and high-pressure working conditions.<\/p>\n<\/div>\n

    <\/div>\n<\/li>\n
  2. \n
    \n

    Mirror Inner Surface<\/strong><\/p>\n

    <\/div>\n

    Inner roughness Ra 0.08\u20130.4\u03bcm<\/strong>, with uniform cross-hatch pattern, reducing fluid resistance and seal wear, improving system efficiency by 5%\u201315%<\/strong>, and preventing oil or air leakage.<\/p>\n<\/div>\n

    <\/div>\n<\/li>\n
  3. \n
    \n

    High Pressure & Wear Resistance<\/strong><\/p>\n

    <\/div>\n

    No oxide layer, no cracks on inner\/outer walls. Honing creates a work-hardened layer and compressive stress, improving fatigue strength by about 30%<\/strong> and extending service life.<\/p>\n<\/div>\n

    <\/div>\n<\/li>\n
  4. \n
    \n

    Excellent Mechanical Properties<\/strong><\/p>\n

    <\/div>\n

    Available in 20#, 45#, 40Cr, 16Mn, 27SiMn, ST52\/E355, 304\/316 stainless steel<\/strong>. Supports bending, flaring, flattening without deformation, suitable for harsh environments.<\/p>\n<\/div>\n

    <\/div>\n<\/li>\n
  5. \n
    \n

    Ready for Assembly<\/strong><\/p>\n

    <\/div>\n

    Finished inner hole quality eliminates secondary machining, saving production time and cost.<\/p>\n<\/div>\n
