The honing/skived and roller burnished seamless steel pipe is cold draw both inside and out, then is given tempering treatment with a tensile strength of up to 520N / mm2 or more. Our factory improves upon the work with our own precision honing/skived roller burnished, using the diameter tolerance of H5~H10. It helps to extend the life of the cylinder, and reduces the wear of the seal.
