Product Feature

The honing/skiving and roller burnishing seamless steel hydraulic tubing, hydraulic cylinder pipe, hydraulic cylinder tube, honed cylinder tubing and honed tubes for hydraulic cylinders are cold draw both inside and out, then are given tempering treatment with a tensile strength of up to 520N / mm2 or more. Then Golden Asia improves upon the work with our own precision honing/skiving and roller burnishing, using the diameter tolerance of H7, H8. It helps to extend the life of the cylinder, and reduces the wear of the seal. The steel grade of The honing/skiving and roller burnishing seamless steel hydraulic tubing, hydraulic cylinder pipe, hydraulic cylinder tube, honed cylinder tubing and honed tubes for hydraulic cylinders include EN 1.0580, E355, STKM13C, STKM13A, STKM11A and DIN ST52.

Formula of Pipe Wall Thickness Pressure Resistant Gauge
  • t = P. D. / 200 S
  • t = Wall Thickness (mm)
  • P = The Largest Pressure (Kg/cm²)
  • D = Steel Pipe Inside Diameter (mm)
  • S = σ / 5 Kg / mm²
  • σ = The Lowest Numerical Value of Tensile (Kg/mm²)
