Honing seamless steel pipes (hydraulic cylinder Steel Tube, pneumatic cylinder tube) produced by undergo cold forcing and annealing for a cured tensile strength reaching over 52kg/cm², before the pipes are milled by precision machinery, regulating the tolerance in inner diameter at an H8-H9 level, with surface roughness at between Ra 0.2μm, which helps to extend the life cycle of the cylinder, and reduces the wear and tear of the seal.
